DR. YVAN FOTSO TOGUEM

Dr Yvan Fotso obtained his PhD in 2024 within Dr. Billy Tene’s PIIVeC (Partnership for Increasing the Impact of Vector Control) project, under the supervision of Prof. Charles Wondji and Prof. Flobert Njiokou.  Prior to joining the Centre for Research in Infectious Diseases (CRID), he made various internships at the Regional Agricultural Research Centre of Nkolbisson (CRRAN) in Yaoundé. During these internships, he actively participated in several activities focusing on biological control methods and pest management including (1) efficacy tests: conducted using microorganism-based formulations (Trichoderma spp. and Bacillus subtilis) against Phytophthora megakarya and Phytopythium spp.; (2) fungicides screening: evaluate fungicides for Cocoa Black pod rot control, and (3) the impact of mirid attacks on the productivity and decline of cocoa tree in Nkoenvone (South, Cameroon). These various field trips allowed him to observe the impact of pesticides on non-target populations in cocoa fields. Dr Yvan Fotso holds a MSc and a BSc in Parasitology and Ecology, obtained at the University of Yaoundé I in 2017 and 2014 respectively. In August 2018, he began an internship in the molecular biology laboratory at CRID, where he pursued his Ph.D. His research is focused on genetics adaptation of mosquitoes under insecticides pressure to find variations that can be used to develop a simple DNA-based tool for the assessment of the impact of metabolic resistance in vector control products in the field.
