🎓 Early Academic Pursuits

Dr. John Kochey Kipyegon’s academic journey is rooted in a strong passion for aquatic ecology and biodiversity. His foundational education began at St. Mary’s Primary School in Mogotio, Kenya, and continued at Nakuru High School where he excelled with a B plain grade. He pursued his undergraduate degree at Moi University, graduating in 1998 with a Bachelor of Science in Fisheries. His academic curiosity led him to Kenyatta University, where he earned a Master of Science in Aquatic Ecology in 2013. His master's thesis focused on the thermal tolerance, density, and distribution of mangrove crabs along the Kenyan coast—laying the groundwork for his advanced studies in aquatic invertebrates. He achieved the highest academic milestone with a Ph.D. in Natural Sciences (Biology) from Johann Wolfgang Goethe University, Frankfurt/Main, Germany in 2018, graduating Magna Cum Laude under a joint DAAD/NACOSTI scholarship. His doctoral thesis explored the evolutionary ecology, utilization, and aquaculture of Macrobrachium spp. in Kenyan rivers, contributing significantly to the field of freshwater biodiversity.
