Mr Bramwel Wanjala | Crop health | Best Paper Award
Senior Research Scientist at Kenya Agricultural and Livestock Research Organization, Kenya
Academic Background:
- Ph.D. in Biotechnology (Expected Dec 2022) – Jomo Kenyatta University of Agriculture and Technology
- M.Sc. in Biochemistry and Molecular Biology (2013) – Egerton University
Expertise:
Dr. Wanjala is a skilled research scientist specializing in plant disease diagnostics, molecular biology, and crop germplasm management. His work has focused on critical plant diseases in Kenya, including Maize Lethal Necrosis (MLN) and various sweetpotato viruses, employing advanced techniques like ELISA, PCR, Q-PCR, and LAMP. At the International Potato Center (CIP), he led sweetpotato virus diagnostics and developed innovative technologies for rapid vine multiplication, like sandponics, significantly aiding the sweetpotato seed system in Sub-Saharan Africa.
Key Contributions and Achievements:
- Capacity Building: Trained numerous researchers and technical staff in virus diagnostics across East and Central Africa, including for KEPHIS.
- Diagnostic Innovations: Validated a ClonDiag Microarray for sweetpotato virus detection, reducing testing time from 6 months to 2 days.
- MLN Lab Establishment: Set up a diagnostic lab for MLN and trained stakeholders in disease identification and management.
- Prebasic Seed Production: Helped establish a sustainable sweetpotato seed production system with KEPHIS, distributing over 150,000 vines to farmers.
