Dr Joseph J Mafurah is a lecturer of Crop Protection (Plant Pathology) in the Department of Crops, Horticulture and Soils. Dr Mafurah holds PhD degree in Plant Pthology (Crop Protection) from Nanjing Agricultural University, China (2015), MSc degrees in Plant Pathology from Kenyatta University  (2010) and a BSc degree in Agriculture Education and Extension from Egerton University (1998). Dr Mafurah joined the Department of Agronomy, Egerton University, as an Assistant Lecturer in July 2011. Since joining Egerton University, Dr Mafurah has scaled academic and professional heights by successfully  completing a PhD degree in China.  Dr Mafurah was examination officer from 2016 to 2021 and currently andn edittor at the Egerton joiurnalScience and technology.

Dr Mafurah has wealth of experience in participatory adaptive research, community outreach and consultancy services focusing on bio-intensive disease management, enhanced food and nutrition security and livelihoods in smallholder agriculture. Over the past one decade, Dr Mafurah has found niche in bio-prospecting for biocontrols for food crops. In the recent years, he has widened his research, outreach and consultancy domain to span underutilized crops (Indigenous vegetables ad forgotten crops), climate change and agro-biodiversity.
