Research Interests

My research focuses on the dynamics and interplay of the human immune system and infectious diseases.  My previous work was on the effect of mass praziquantel treatment on anti-schistosome immune responses in school children and the impact of infection with schistosomiasis mansoni on vaccine responses. I am now part of an ongoing collaborative study with Prof. Timothy Anderson, Dr. Frederick Chevalier, and Dr. Winka LeClech of Texas Biomedical Research Institute in San Antonio, Texas, USA and Professor Phillip LoVerde of the University of Texas Health Science Center, San Antonio, Texas, USA. My collaborative research work in schistosomiasis control is based at the Kenya Medical Research Institute’s Centre for Global Health Research (KEMRI-CGHR) campus where I run a well-established snail and hamster rearing facility with all requisite infrastructure for supporting field activities in a schistosomiasis endemic area near Lake Victoria.  My plan is to build a strong research team in the field of infectious diseases while augmenting my knowledge and skills in research ethics, population genetics, genomics and computational biology. I am especially committed to research that will continue to advance the work of schistosomiasis control, with the focus now being to investigate praziquantel resistance in schistosomes, identifying mutations underlying resistance in schistosome parasites from the field in western Kenya. I am also currently involved in collaborative research work on Covid-19 epidemiology and persistence and immunity, together with colleagues at Kenyatta University, KEMRI and Kenyatta National Hospital.

2021-2022: MERCK Schistosomiasis Research Grant Initiative

Project Title: Molecular Surveillance of Praziquantel Resistance
Role: Principal Investigator (PI)
Collaborations: Kenya Medical Research Institute, Texas Biomedical Research Institute
Overall Goal: The objectives of this study will be to (i) screen for TRPM-PZQ sequence variation in field collected schistosome populations in Western Kenya, and (ii) identify potential key mutation(s) in TRPM-PZQ gene which might play a role in PZQ treatment failure in ‘persistent hotspots’, Kenyan high schistosome transmission area.
Grant Value: EURO 30,000
