Early Childhood And School Life
Dr Lusike A. Wasilwa was born on 22 June 1963 in Nakuru County, Kenya. She was the second born daughter to the late Mrs Damaris Kinavadoli Wasilwa and Engineer Festus Wasilwa.
Lusike began her education at Oral Drummonds Nursery School in Kilimani, Nairobi, from where she proceeded to Nairobi Primary School. After passing the Certificate of Primary Examination with flying colours, she was admitted to Kenya High School; one of the few national schools at that time. Lusike took both her ‘O’ and ‘A’ level examinations at the school. She served as a prefect at Kenya High, an opportunity that contributed to the honing of her well-known leadership skills.
From her earliest days, Lusike showed determination and an unwavering commitment to excellence. These traits defined her personal and professional journey, enabling her to rise as one of Kenya’s and Africa’s most distinguished agricultural scientists.
University Education
Lusike pursued an undergraduate degree in agriculture at the University of Eastern Africa, Baraton between 1982 and 1985. She enjoyed her classes in agriculture tremendously, and it was during this period that her exceptional intellectual capacity became evident. Her academic performance was recognized with her placement on the Dean’s List of Excellence — an early indicator of the rigour, discipline, and drive that would come to define her professional life. She also made notable contributions, such as reporting on citrus greening and avocado root rot in Kenya. At university, Lusike discovered her passion for horticulture while working on an undergraduate project that trained farmers around Barton to establish small kitchen gardens. As she became increasingly engaged in community work, her desire to improve the lives of rural farmers was firmly cemented.
After working for a short period after her first degree, Lusike secured a graduate assistantship at the University of Arkansas in the United States, where she pursued a Master’s in Horticulture(1989–1992) followed by her Ph.D. in Plant Science (1993–1997). Her doctoral research broke new ground in understanding anthracnose disease in cucurbits. She then undertook a postdoctoral fellowship at Rutgers University, New Jersey (1998–2002), specializing in blueberry and cranberry diseases. Through her Ph.D. and postdoctoral work in molecular plant pathology, Lusike gained expertise in cutting-edge molecular techniques, including genetic diversity characterization in lab-based diagnostic techniques and genetic analysis, amongst others.
Career
Lusike’s professional career, spanning nearly four decades, began with her recruitment as a plant breeder at the Kenya Agricultural Research Institute’s (KARI) National Horticultural Research Centre in Thika in 1986. Working directly with farmers, she developed a deep understanding of local contexts and the complex realities faced by smallholder farmers in Kenya. Her career culminated in her appointment as Director of Crop Systems at the Kenya Agricultural & Livestock Research Organization (KALRO), a position she held from 2015 until her passing. Over those years, Lusike’s contributions went far beyond groundbreaking research to include exemplary leadership and mentorship. She was widely regarded as a global voice for horticulture and agricultural development.
Upon the completion of her post-graduate studies in the United States, Lusike rejoined KARI as a programme officer before being promoted to the position of Assistant Director in the Horticulture and Industrial Crops Division. This was a position of considerable responsibility, placing Lusike at the centre of research for the important horticulture sector in Kenya. She provided leadership in defining research priorities for a wide array of fruits, vegetables, and high-value horticultural crops.
Following the transformation of KARI into KALRO, Lusike took on a new, pivotal role as Director of Crop Systems —positioning her at the forefront of policy-making and strengthening the institution’s global presence. Through this position, she shaped a lasting legacy at KALRO, weaving her systems-based and resilience-focused vision into the DNA of Kenya’s premier agricultural research body.
Her career path was 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.
Professional Achievements
Lusike served in numerous high-profile roles, with influence extending across Africa and beyond. She chaired and convened major scientific gatherings, including the First All Africa Horticulture Congress in 2009 and the International Symposium on Horticultural Development in 2010. Lusike served on the board of the East African Science and Technology Commission, where she helped shape the science and technology agenda of the entire East African Community ensuring that agricultural research priorities in Kenya were well articulated within broader regional goals and collaborations. In addition, as a board member of the Pest Control Products Board and the Kenya National Accreditation Service, she ensured that institutional decisions were informed by rigorous scientific evidence and upheld the highest standards of quality and safety.
Lusike’s other professional roles included serving on the Advisory Board of Emerge Africa, the Kenya Avocado Project, One Acre Fund, and the Research Grant Management Committee of Kenya Climate Smart Agriculture Project. She was also a board member of Ustadi and the African Journal for Horticultural Science. She served as vice chair and then chair of the Horticulture International Advisory Board for Horticulture Collaborative Research Support Program, chair of the Southern and Eastern Cotton Forum, and member of the Kenya Agricultural Productivity Programme, the Commission for Higher Education, and the Kenya Agricultural Productivity and Agribusiness Programme’s grants advisory and approval committees.
Beyond her national contributions, Lusike played an active role in multiple global committees convened by the United Nation’s Food and Agriculture Organization (FAO), the United States Agency for International Development (USAID), and other international research networks, which was important for connecting Kenyan research to global networks and funding streams. Her long-term engagement with the USAID’s Feed the Future Innovation Lab for Horticulture (formerly the Horticulture Collaborative Research Support Program) is a prime example. She served as an international advisory board member, later becoming vice chair and then chair of the board. This leadership role was instrumental in guiding the priorities of a major international research-for-development programme to ensure its relevance and impact in partner countries like Kenya.
In her lifelong commitment to smallholder farmers, Lusike enriched livelihoods by developing 11 macadamia nut varieties, promoting underutilized fruit crops, and pioneering guava and gooseberry breeding programmes that expanded both opportunity and resilience. She also championed indigenous vegetables and supported farmer-led seed enterprises, leaving an enduring impact on food security and nutrition in Kenya and the region. She was a prolific writer, authoring and co-authoring more than 100 scientific articles and technical papers aimed at advancing the scholarly literature on the management of agricultural systems in Africa.
Lusike’s legacy is felt not only in research and leadership but also in the strategic projects she helped establish, such as the East Africa Regional Centre for Horticulture Innovation, Kenya’s first Horticulture Practical Training Centre, and numerous community initiatives promoting nutrition and sustainable agriculture.
Lusike’s service and excellence were recognized with numerous awards and honours. She was a recipient of three medals from the International Society for Horticultural Science in recognition of her service, and in 2011 she was awarded the USAID/CAADP Champion for Change. She also received multiple scientific prizes for research excellence at KARI conferences for her prolific writing.
Mentoring The Next Generation Of African Scientists And Leaders
Among Lusike’s enduring legacies was her steadfast commitment to mentoring the next generation of scientists. As a pioneer fellow then mentor in the AWARD fellowship programme, she not only enhanced her own leadership skills but also discovered her gift for guiding and inspiring others. Recognized in 2010 for her excellence in mentorship, she became a role model within the African scientific community. Her influence extended beyond individuals to institutions, including her leadership as chair of the Board of Management of the Kenyan chapter of AWARD (Ke-AWARD), where she fostered collaboration and networking among fellows. For Lusike, mentorship was a way of giving back and paying it forward for the training she had received. And through this, she nurtured and inspired countless young professionals in the agriculture sector and beyond.
Throughout her life, Lusike embodied the values of excellence, integrity, and service. She believed in science as a tool for transforming lives, uplifting communities, and ensuring Africa’s place in global agricultural development.
Enduring Love For Her Family
Lusike loved her family deeply, and each member held a special place in her heart. She often spoke of her father as her greatest role model, describing him as a principled, incorruptible and effective leader—qualities that inspired her throughout her life. From him, she inherited the values of excellence, integrity, and efficiency, principles that defined her professional life. From her mother, she inherited a spirit of kindness and generosity, which shaped her personal relationships as well as her career. She also drew from her mother’s courage and determination, facing every challenge with resilience and an unwavering will to persevere against all odds. Her warmth, generosity of spirit, empathy, and compassion, made a lasting imprint on her friends, relatives, university peers, and colleagues at KALRO.
Lusike cherished her siblings— the late Dr Harrison, Jane, Victor, and Mary. Their triumphs her triumphs, and in times of difficulty, she stood firmly by their side with unwavering support and encouragement. Among her greatest joys, however, were her beloved nieces, Dr Timina and Josie. She loved and cherished them deeply and was deeply committed to helping them achieve their dreams, often taking them to her professional meetings to inspire and encourage them. The day Dr Timina graduated as a medical doctor filled Lusike with immense pride, a milestone she celebrated joyfully with her friends from near and far. Today, we are confident that she is now watching over Josie from up above with the same love, devotion, and encouragement to succeed and fulfil her dreams.
The passing of her beloved mother, coming so soon after the demise of her brother, Harrison, was a heavy blow for Lusike. Yet, even in her own grief, Lusike put the needs of her family above her own, providing strength and comfort to her family, especially her father.
That was the Lusike we all knew and loved; a remarkable woman, whose love for her family was boundless and unwavering.
Illness
Lusike had been unwell for some time, and after several hospital visits and extensive tests, she was diagnosed with an autoimmune condition known as Sjögren's Syndrome. This diagnosis marked the beginning of a long period of treatment and several hospital admissions. About three months ago, Lusike’s health declined rapidly, making it difficult for her to eat. Her final admission to hospital was on Monday, 8 September at Coptic Hospital. Although she initially responded well to the administered treatment, her condition worsened and on Thursday, 18 September 2025, she was admitted to HDU. In the early hours of Saturday, 20 September, Lusike passed away despite doctors’ best efforts to resuscitate her.
Summary
Lusike’s life serves as a beacon of inspiration and proof that with hard work, vision, and commitment one can shape not only national policy and research agendas but also the livelihoods of countless farmers and families. Lusike (popularly known as Aliboy to her friends) lived fully, served faithfully, and leaves behind a legacy that will continue to flourish for generations to come.
May our Lusike’s soul rest in eternal peace.
