His research interests include tropical diseases, epilepsy, and infectious diseases outbreaks like COVID-19 and Mpox. Currently, he serves as a research professor at the University of Antwerp while also maintaining an affiliation as research officer at the Brain Research Africa Initiative (BRAIN) in Cameroon while continuing research activities with the University of Antwerp. He has cumulated years of field experience in several African countries where he has conducted onchocerciasis and epilepsy surveys in remote villages.
