The formidable career of Dr. Lusike Wasilwa was built upon an academic foundation that was both distinguished and strategically significant. Her educational trajectory, which seamlessly combined a deep grounding in the local agricultural context of Kenya with elite scientific training in the United States, established the intellectual and professional bedrock for her subsequent decades of leadership and innovation. This dual perspective was not an incidental detail of her biography but a central, recurring theme that enabled her to function as a highly effective bridge between global scientific advancements and the specific, on-the-ground needs of African agriculture.

Early Promise and Local Grounding

Dr. Wasilwa’s journey in agricultural science began at the University of Eastern Africa, Baraton, in Kenya, where she pursued a Bachelor of Science (BSc) degree in Agriculture.¹ This initial phase of her higher education was crucial, as it immersed her in the core principles of agriculture within the specific agro-ecological and socio-economic context of East Africa. An undergraduate education in Kenya provides an essential, practical understanding of the region’s unique soil types, climatic variabilities, endemic pests and diseases, and the complex realities faced by the smallholder farmers who form the backbone of the nation’s food system. It was during this period that her exceptional intellectual capacity became evident. Her academic performance was recognized with a placement on the Dean’s List of Excellence, an early indicator of the rigor, discipline, and drive that would come to define her professional life.¹ This early distinction signaled a scholar of significant promise, one already excelling within her home country’s academic system before seeking further specialization abroad.

Advanced Scientific Training in the United States

Building on her strong undergraduate foundation, Dr. Wasilwa pursued advanced postgraduate studies in the United States, a move that would profoundly shape her technical expertise and expand her professional networks. She enrolled at the University of Arkansas in Fayetteville, where she earned both a Master of Science (MSc) in Horticulture and a doctorate (Ph.D.) in Plant Science.¹ This period of intensive study allowed her to specialize and develop deep expertise in crop science. Her academic journey in the U.S. culminated in a post-doctoral fellowship at Rutgers University in New Jersey.¹ This post-doctoral position was particularly formative, as it would have exposed her to the forefront of research in fields such as molecular plant pathology. This level of training provided her with mastery over sophisticated, lab-based diagnostic techniques, genetic analysis, and other cutting-edge scientific methodologies that were globally recognized as the state of the art.

This combination of a Kenyan undergraduate degree followed by advanced postgraduate and post-doctoral training in the United States was a critical component of her professional identity. It created a powerful synergy, equipping her with a rare and valuable dual perspective. She possessed not only the contextual intelligence born from her Kenyan education—an innate understanding of what solutions are practical, adoptable, and relevant to a Kenyan farmer—but also the high-level technical expertise from her U.S. training to develop and validate those solutions with world-class scientific rigor. This fusion of local knowledge and global science was a primary driver of her career’s effectiveness, allowing her to accurately diagnose local problems and apply globally recognized best practices to solve them. She was, in effect, a conduit through which global scientific innovation is translated and tailored to address the specific challenges of African food systems. This unique background explains the consistent success and impact that characterized her entire career arc, from her earliest research papers to her final leadership role.

II. A Career in Public Service: Leadership at KARI and KALRO

Dr. Lusike Wasilwa’s professional career was a compelling narrative of ascent through the ranks of Kenya’s national agricultural research system. Her trajectory was marked by a deliberate and significant evolution, not merely in title but in the scope and nature of her responsibilities. This progression from a technical specialist focused on a specific sub-sector to a high-level strategic manager overseeing the nation’s entire crop research agenda reflected both her personal intellectual growth and the broader maturation of agricultural science itself, which has increasingly moved toward holistic, systems-based approaches.

Early Leadership at KARI

Dr. Wasilwa’s leadership journey began at the Kenya Agricultural Research Institute (KARI), the precursor to the modern-day KALRO. At KARI, she served as the Assistant Director in charge of Horticulture and Industrial Crops Research.² This was a position of considerable responsibility, placing her at the center of research for a vital component of Kenya’s agricultural economy. Horticulture is a key source of income, employment, and export revenue for the country, and her role involved guiding the research priorities for a wide array of fruits, vegetables, and other high-value crops. During this period, her experience was further enriched by work with the Institut National des Recherches Agricoles du Bénin (INRAB) in Benin.⁶ This engagement provided her with a valuable, broader perspective on the agricultural challenges of West Africa, complementing her deep expertise in the East African context and fostering a more continental understanding of food production systems.

Strategic Leadership at KALRO

The establishment of the Kenya Agricultural & Livestock Research Organization (KALRO) marked a significant restructuring of the national research system, and Dr. Wasilwa ascended to a new, pivotal role within the organization. She was appointed Director of Crop Systems, based at the KALRO headquarters secretariat in Nairobi.¹ This appointment represented far more than a simple promotion; it signified a fundamental shift in scale and conceptual approach. The transition from “Assistant Director, Horticulture and Industrial Crops” to “Director, Crop Systems” was emblematic of a move from a commodity-centric focus to a holistic, systems-level perspective.

In modern agricultural science, the term “crop systems” encompasses the entire ecosystem of crop production. It extends beyond the plant itself to include soil health, genetic resource management, water use, pest and disease ecology, post-harvest handling, value chain integration, market linkages, and the overarching policy environment. As Director of Crop Systems, Dr. Wasilwa was responsible for providing leadership and coordination across this entire integrated spectrum for all food, horticulture, and industrial crops. Her role was to ensure that KALRO’s research was not conducted in silos but was instead demand-driven, innovative, and aligned with the national goal of creating a more productive, resilient, and competitive agricultural sector.⁹

This evolution in her professional role mirrored the development of her own research interests, which had broadened from specific investigations in plant pathology to systemic issues like “mainstreaming biodiversity” and promoting “precision agriculture”.¹ Her position as Director provided the institutional platform to translate this personal vision into national strategy. This was confirmed by her active participation as a member of the Steering Committee involved in developing KALRO’s Strategic Plan.¹² This placed her at the very heart of defining the organization’s future direction, ensuring that her systems-based, resilience-focused approach was embedded in the institutional DNA of Kenya’s premier agricultural research body. Her career path was thus a clear demonstration of a leader who had grown from a specialist into a true systems thinker, capable of architecting a comprehensive research agenda for an entire nation.

III. Scientific Contributions and Research Portfolio

Over a research career spanning more than 35 years, Dr. Lusike Wasilwa authored and co-authored a substantial body of scientific work that has significantly advanced the understanding and management of agricultural systems in Africa.¹ Her publication record, which includes numerous scientific articles and technical papers, demonstrated both deep specialization and a broadening strategic vision over time.¹ An analysis of her research portfolio reveals a sophisticated intellectual journey that began with the precise diagnosis of specific problems at the plant and pathogen level and logically progressed to the ambitious goal of redesigning entire agricultural systems for greater resilience and productivity. This progression showcased a rare ability to operate effectively at both the microscopic scale of molecular biology and the macroscopic scale of national food policy.

3.1: Foundational Work in Molecular Plant Pathology

The bedrock of Dr. Wasilwa’s scientific expertise lay in the field of horticulture and, more specifically, molecular plant pathology.¹ Her early and ongoing work in this area was crucial for identifying and characterizing the diseases that threatened Kenya’s most important crops. A key contribution in this domain was her involvement in “first report” publications. In plant pathology, a first report is a scientifically significant event, as it officially documents the presence of a pathogen in a new geographical area or on a new host plant, which is the critical first step for developing effective quarantine measures, disease management strategies, and breeding programs for resistance.

Her recent work exemplified this. In 2021, she was a co-author on two such landmark papers published in New Disease Reports. The first was the First report of Potato spindle tuber viroid infecting tree tomato in Kenya in mixed infection with Potato virus Y.⁶ The second was the

First report of Ethiopian tobacco bushy top virus and its associated satellite RNA in mixed infection with Potato virus Y infecting Solanum betacea in Kenya.⁶ These discoveries, which utilized modern molecular techniques, provided the Kenyan agricultural sector with vital intelligence on emerging threats to the tree tomato, an important horticultural crop.¹³ Her work also extended beyond viral pathogens. A 2012 paper in the

European Journal of Plant Pathology on the Characterization of isolates that cause black rot of crucifers in East Africa demonstrates a regional scope to her pathology research, addressing a significant bacterial disease affecting vegetables like cabbage across multiple countries.⁶ This foundational diagnostic work provided her with the granular, evidence-based understanding of the specific threats that undermine agricultural productivity.

3.2: Enhancing Productivity in Key Crops

Building upon her diagnostic expertise, Dr. Wasilwa’s research also focused on developing practical solutions to enhance crop productivity and resilience. This work often bridged the gap between fundamental science and applied agriculture. A prime example is her 2023 co-authored publication in the prestigious journal Phytopathology on the Characterization of Blast Resistance in a Diverse Rice Panel from Sub-Saharan Africa.⁶ Rice blast, caused by the fungus

Magnaporthe oryzae, is one of the most devastating diseases of rice worldwide. This research, which screened a diverse collection of rice varieties from the region, is vital for identifying sources of genetic resistance that can be used by plant breeders to develop new, resilient rice cultivars, thereby contributing directly to food security in a continent where rice consumption is rapidly increasing.

Furthermore, Dr. Wasilwa had recognized that technological innovation alone is insufficient without farmer adoption. Her research therefore delved into the socio-economic factors that influence the uptake of new technologies. Her 2016 paper in the African Journal of Food, Agriculture, Nutrition and Development, titled Assessing the determinants of tissue culture banana adoption in western Kenya, is a case in point.⁶ This study moved beyond the lab to understand the real-world decisions of farmers, examining how factors like farm size, education level, and gender of the household head influence the choice to adopt tissue culture bananas, a technology that offers disease-free planting material and higher yields. This type of research is crucial for designing more effective extension programs and ensuring that scientific breakthroughs translate into real impact in farmers’ fields.

3.3: A Strategic Pivot to System-Level Resilience

In line with her ascent to a national leadership role, Dr. Wasilwa’s more recent research focus reflected a higher level of strategic thinking, aimed at building robust and resilient agricultural systems. This work was characterized by three interconnected themes:

1. Mainstreaming Biodiversity: Dr. Wasilwa was a prominent advocate for the conservation, utilization, and commercialization of underutilized, neglected, and indigenous crops.¹ She championed research and development at KALRO on a wide range of these species, including fruits like gooseberries, guavas, and jackfruit; drought-tolerant grains like sorghum and millet; and nutritious African Indigenous Vegetables (AIVs) such as nightshade (Managu) and spider plant (Sagaa).¹⁶ Her rationale was that these crops, often ignored by mainstream agricultural research, are better adapted to local conditions, more resilient to climate shocks, and can play a critical role in diversifying diets and improving nutrition security.¹⁶
2. Precision Agriculture: She actively promoted the use of modern, precise technologies to increase production and productivity while minimizing waste and environmental impact.¹ This approach involves using data and technology to optimize inputs like water and fertilizer and to more effectively manage pests and diseases, leading to more efficient and sustainable farming practices.
3. Post-Harvest Management: Recognizing that significant losses occur after crops leave the field, a substantial part of her focus was on reducing pre-and-postharvest losses.¹ This included research on and promotion of innovative, low-cost technologies suitable for smallholder farmers. Her work on evaluating the efficacy of the Coolbot™ cold room for extending the shelf life of perishable horticultural commodities like mangoes is a clear example of her commitment to finding practical solutions to this pervasive problem.¹⁷

This logical progression—from diagnosing diseases, to improving specific crops, to redesigning the entire system—demonstrated a comprehensive and strategic approach to agricultural research and development. It was this ability to connect the dots from the molecular level to the market level that defined her unique contribution to the field.

IV. Championing Agricultural Innovation and Food Security in Kenya

Dr. Lusike Wasilwa’s influence extended far beyond the laboratory and the pages of scientific journals. She had established herself as a formidable public advocate and a key driver of agricultural innovation on the ground in Kenya. Her work was characterized by a pragmatic focus on translating research findings into actionable strategies and technologies that directly benefit farmers, enhance food security, and create new economic opportunities. She was a vocal champion for a more diverse, resilient, and market-oriented agricultural sector, consistently working to bridge the gap between scientific evidence and practical application.

Advocacy for Underutilized and Indigenous Crops

One of the most significant themes of Dr. Wasilwa’s public work was her passionate and evidence-based advocacy for neglected, underutilized, and indigenous crop varieties. She had argued compellingly that these crops, which have often been “pushed into forgetfulness,” hold immense potential for improving nutrition, boosting farmer incomes, and building resilience in the face of climate change.¹⁶ She correctly identified that these species have been historically ignored by mainstream agricultural research and extension curricula, despite their adaptability and nutritional qualities.¹⁶

Under her leadership at KALRO, this advocacy was translated into concrete action. The organization has actively engaged in developing, improving, and disseminating a wide range of these crops to farmers. This initiative includes the introduction and promotion of numerous fruit varieties such as 12 types of gooseberries, 25 guavas, and 2 jackfruits, as well as drought-tolerant grains like sorghum and millets, which are critical for food security in Kenya’s arid and semi-arid lands.¹⁶ In partnership with bodies like the Kenya Plant Health Inspectorate Service (KEPHIS), KALRO has also been instrumental in the official release of improved varieties of African Indigenous Vegetables (AIVs), including nightshade (

Managu), vine spinach (Nderma), and spider plant (Sagaa), to meet rising consumer demand.¹⁶ This work is a direct and strategic intervention designed to diversify Kenya’s food basket, making the entire food system less vulnerable to shocks that can affect staple cereals like maize.

Bridging the “Evidence to Action” Gap

A core element of Dr. Wasilwa’s philosophy was her commitment to closing the gap that so often exists between research and its end-users. At the 2017 “Evidence to Action” conference, she articulated her purpose for attending as being focused on “demystifying technologies” and “trying to bridge that gap” to ensure innovations make a real-world difference.⁷ This perspective informed her approach to agricultural development, which emphasized multi-stakeholder collaboration. She was a strong proponent of public-private partnerships (PPPs) as a mechanism to scale up the adoption of new technologies and research products.¹⁸ She advocated for an integrated system that brings together researchers, academia, farmers, entrepreneurs, and the private sector to act as a “brokerage of knowledge, information and technologies,” ensuring that innovations were not just developed but were also effectively taken up and scaled.¹⁸

Expanding Market Frontiers

Dr. Wasilwa’s vision for Kenyan agriculture was not limited to subsistence and local consumption; she was also keenly focused on expanding the sector’s commercial potential and access to international markets. Her analysis was forward-looking and grounded in economic reality. For instance, in the context of chili farming, she had publicly stated that Kenya is exploiting only half of its production potential. She went further to identify specific, high-potential export markets that Kenya could target, including the United States, the Netherlands, Germany, the UK, and the UAE, demonstrating a strategic, market-driven mindset.¹⁹ This approach helps to align national research priorities with global market opportunities, creating pathways for farmers to increase their incomes by participating in high-value export chains.

Public Engagement and Education

Dr. Wasilwa had embraced her role as a public intellectual, using her platform to educate, inspire, and contribute to national policy debates. She was a sought-after keynote speaker, delivering powerful messages to diverse audiences. At a university research conference in 2022, she made a clarion call for Kenyan youth to engage in farming, reminding them of the fundamental importance of agriculture with the memorable phrase, “You need a farmer 3 times a day”.²⁰ She also participated in high-level public forums on contentious and critical policy issues, such as a panel discussion on the impact of lifting the GMO ban on Kenya’s fresh produce trade, where she shared the stage with the CEOs of the National Biosafety Authority and the Pest Control Products Board.²¹ Her public outreach also proved vital during times of crisis. Amid the COVID-19 pandemic, she spoke at the Mashariki Summit about the innovations KALRO was deploying to ensure national food security, demonstrating leadership and providing reassurance during a period of global uncertainty.²² Through this consistent public engagement, she helped to shape public opinion and policy, ensuring that agricultural science remained central to the national conversation.

V. Influence and Governance: Shaping Policy Through Strategic Affiliations

A comprehensive understanding of Dr. Lusike Wasilwa’s impact requires an analysis that extends beyond her direct research and leadership at KALRO. A key dimension of her career was her extensive and highly strategic service on a wide array of boards, advisory committees, and governing bodies. This was not a passive collection of honorary titles but rather a deliberate and sophisticated engagement with the entire agricultural innovation ecosystem. By operating at the critical nexus of research, policy, regulation, funding, and international partnership, Dr. Wasilwa was able to influence and shape the very structures that govern the creation and dissemination of agricultural knowledge in Kenya and East Africa. She had, in effect, acted as an architect of this ecosystem, ensuring that its various components were aligned and informed by scientific evidence.

A Network of Strategic Influence

Dr. Wasilwa’s board and committee memberships can be categorized by their function, revealing a comprehensive network of influence that spanned every stage of the innovation pipeline:

Notably, she served as the Principal Consultant for the development of the Regional Potato Strategy & Action Plan 2022-2032. This role placed her at the forefront of shaping the future of a critical food security crop for the entire region.
• National Regulation and Standards: Dr. Wasilwa served as a board member for two critical national regulatory bodies: the Pest Control Products Board (PCPB) and the Kenya National Accreditation Service (KENAS).¹ Her presence on the PCPB ensured that decisions regarding the registration and use of pesticides and other crop protection products were informed by sound scientific evidence on efficacy and safety. Her role at KENAS, the national body for accreditation of laboratories and certification bodies, allowed her to contribute to maintaining high standards of quality and competence in the scientific infrastructure that underpins the agricultural sector.
• Research and Development Funding: She held influential positions on the grants advisory and approval committees for several of Kenya’s most significant agricultural development programs. These included the Kenya Agricultural Productivity Programme (KAPP), the Kenya Agricultural Productivity and Agribusiness Programme (KAPAP), and the Kenya Climate Smart Agriculture Project (KCSAP).¹ These roles were particularly powerful, as they allowed her to directly influence how national and donor funds were allocated, enabling her to champion investment in research areas aligned with her strategic priorities, such as climate resilience, biodiversity, and post-harvest management.
• International Collaboration and Partnerships: Dr. Wasilwa was a key figure in connecting Kenyan research to global networks and funding streams. Her long-term engagement with the U.S. Agency for International Development’s Feed the Future Innovation Lab for Horticulture (formerly the Horticulture Collaborative Research Support Program, or HortCRSP) is a prime example. She served as an International Advisory Board Member and, notably, as both Chair and Vice Chair of the board.¹ This leadership role was instrumental in guiding the priorities of a major international research-for-development program to ensure its relevance and impact in partner countries like Kenya.
• Civil Society and Knowledge Dissemination: Her commitment to the broader scientific and development community was evident in her service on the boards of organizations like USTADI, a capacity-building NGO, and Emerge Africa, an innovation center.¹ Furthermore, her position on the advisory board for the African Journal for Horticultural Science helped to uphold the quality and relevance of scientific publishing on the continent.¹

This multi-faceted engagement created a powerful, self-reinforcing system. The insights gained from her research at KALRO could directly inform the funding priorities she advocated for on the KCSAP committee. The challenges identified in regional policy discussions at EASTECO could be addressed through international collaborations forged via the Horticulture Innovation Lab. The regulatory hurdles faced by farmers could be examined from an evidence-based perspective at the PCPB. This intricate network of affiliations demonstrated a highly effective mode of leadership that multiplied her individual impact exponentially, allowing her to not only conduct research but to actively architect the environment in which that research could thrive and achieve scale.

VI. A Legacy of Mentorship: Empowering the Next Generation

Among the many facets of Dr. Lusike Wasilwa’s distinguished career, her profound and sustained commitment to mentorship stood out as a cornerstone of her legacy. For Dr. Wasilwa, mentoring was not a peripheral activity or a mere personal act of giving back; it was a core professional strategy for building sustainable human and institutional capacity, fostering leadership, and deliberately addressing the historical gender imbalance within African agricultural science. This commitment was most vividly demonstrated through her deep and long-standing involvement with African Women in Agricultural Research and Development (AWARD), an organization whose mission aligned perfectly with her own dedication to empowering the next generation.

Commitment to African Women in Agricultural Research and Development (AWARD)

AWARD is a career-development program that works to strengthen the research and leadership skills of women agricultural scientists across sub-Saharan Africa.²⁸ Dr. Wasilwa was an integral part of this initiative for many years, serving as both a fellow and a mentor.⁴ Her contributions were so significant that in 2010, she was formally recognized by AWARD for her “dedication and commitment to excellence in mentoring” for the period from 2008 to 2010.² This award was not just a recognition of her efforts but an affirmation of her status as a role model for effective mentorship within the African scientific community.

Her involvement went beyond individual mentoring relationships. Demonstrating a commitment to institutionalizing this practice, Dr. Wasilwa took on a key leadership role as the chair of the board of management for the Kenyan chapter of AWARD, known as Ke-AWARD.³⁴ In this capacity, she helped to drive the agenda for women in agricultural research and development within her home country, working to create a sustainable vehicle to “drive the message that agriculture is truly profitable” and to foster networking and collaboration among the 48 Kenyan women researchers who are part of the chapter.³⁴

The Multiplier Effect of Mentorship

The impact of Dr. Wasilwa’s mentorship can be seen in the successful careers of those she guided. A powerful and concrete example is her relationship with her AWARD mentee, Dr. Jane Ambuko.³⁵ Dr. Ambuko is now a Professor of Horticulture at the University of Nairobi and a leading expert in post-harvest technology in her own right. The success of this mentoring relationship is evident in their continued professional collaboration; they frequently shared public platforms, such as the high-level panel on GMOs, where Dr. Wasilwa was a panelist and Prof. Ambuko served as the moderator.²¹ This demonstrates the “multiplier effect” of effective mentorship: it cultivates new leaders who, in turn, contribute to the scientific community and mentor others, creating a virtuous cycle of capacity building.

This work was situated within a critical context. As of the early 2010s, female researchers made up less than 25 percent of Africa’s agricultural scientists.³⁶ Dr. Wasilwa’s dedicated efforts in mentoring women were therefore a direct and strategic intervention aimed at correcting this stark gender disparity. By equipping younger female scientists with the skills, confidence, and networks to succeed, she was actively working to plug the “leaky pipeline” that sees many talented women leave scientific careers. Her actions are a testament to her understanding that for African agricultural innovation to be truly effective and equitable, it must draw on the talents and perspectives of all its potential contributors. Her legacy, therefore, lies not only in the science she produced but also in the new generation of scientific leaders she helped to nurture.

Her journey from a promising young scholar in rural Kenya to one of the most influential figures in African agricultural research is a testament to her intellectual prowess, unwavering dedication, and strategic acumen.

As a scientist, her contributions were both foundational and forward-looking. Her meticulous work in molecular plant pathology provided the Kenyan agricultural community with the critical diagnostic intelligence needed to combat emerging crop diseases. This deep understanding of specific threats then informed her evolution into a systems thinker, capable of designing broad, strategic interventions. Her focus on mainstreaming biodiversity through the promotion of underutilized crops was not merely a research interest; it was a direct, pragmatic response to the dual crises of climate change and malnutrition, offering farmers more resilient livelihoods and consumers more diverse and nutritious diets.

However, her impact could never be measured by her publications alone. Dr. Wasilwa demonstrated a rare ability to architect the very ecosystem in which agricultural innovation occurs. Through her tireless service on a vast network of national, regional, and international boards, she influenced policy, guided funding, set regulatory standards, and forged global partnerships. This strategic engagement created a self-reinforcing loop where her research informed policy, and policy, in turn, created a more enabling environment for impactful research. She did not simply work within the system; she actively shaped it.

Perhaps her most enduring legacy is the human capacity she built. In a continent where women remain significantly underrepresented in the sciences, her commitment to mentoring through programs like AWARD was a transformative act. By nurturing a new generation of female scientific leaders, she created a multiplier effect that will continue to yield benefits for decades to come. The success of her mentees is a living testament to her belief that empowering people is the most sustainable way to build resilient institutions.
