SUMMARY

Dr. John Nduko holds a PhD and Master of Engineering in Biotechnology specializing in industrial biotechnology from Hokkaido University, Japan and B.Sc. in Food Science and Technology (First class) from Egerton University. He is currently a Senior Lecturer of Food Biotechnology and Food Microbiology at the Department of Dairy and Food Science and Technology, Egerton University, Kenya. He has worked as a research fellow at Hokkaido University in the past and his research interests range from Microbial Biotechnology, Food Science, Genetic and Metabolic Engineering to Bioprocess Development. Dr. Nduko has developed a strong record in research focusing on DNA-based diagnostic techniques to characterize microorganisms in traditionally fermented food products. He has also research interests in food product development, climate change an food systems transformation, food safety, circular bioeconomy and food processes development. Towards this end, he has attracted 8 research grants as a PI or collaborator and been involved in a number of consultancies. Mainly, Dr. Nduko is also involved in the designing of a new fruits and vegetable dehydration plant with the government of Kenya as a Food safety expert (Kenya defense forces). Dr. Nduko has authored 55 articles in peer-reviewed journals among them 6 book chapters and he has has presented his research work in over 50 international conferences all over the world. He has supervised 16 MSc. students and 2 PhD student to completion and is currently supervising 11 others (Including 1 PhD). Dr. Nduko also currently serves as a member of the Resource Mobilization Sub-Committee of the East African Science and Technology Commission (EASTECO), Biosafety expert (Roster of Experts) for the National Biosafety Authority of Kenya–Biotechnology and Biosafety disciplines (NBA) and has been involved in the assessment of the safety of Genetically Modified DNA vaccines. At the University, Dr Nduko is serving as an Associate Dean (Faculty of Agriculture), Science, Technology and Innovation (STI) champion, and has served as Departmental Examination Officer and Faculty Management Committee member, Student Advisor, Research sub-Committee member of Egerton University, Food Safety Management Team Member, Member of the Data Management and Curation Strategy Committee, Acting Departmental Chairman on certain dates, and a member of postgraduate committee at the Faculty in the past. Dr. Nduko has also served as postgraduate thesis examiner (Internal and external) and supervised a number of undergraduate student projects some of which have been published. Moreover, Dr. Nduko has been involved in developing proposals and consultancy bids for the University.
