Bel Youssouf G. Mountessou is a Researcher and Lab Technical Assistant at the Humboldt Research Hub‑CECANAPROF (https://cecanaprof.org/), Department of Chemistry, Higher Teacher Training College, University of Yaoundé 1, and a Lecturer at the Department of Applied Chemistry, Faculty of Science, University of Ebolowa (Cameroon). In 2021, he completed his PhD in Organic Chemistry from the University of Yaoundé 1. His primary research interest is the isolation and characterization of bioactive secondary metabolites from fungi and medicinal plants, targeting anti‑infective and cytotoxic activities against infectious diseases and cancer. As a complementary approach (he also holds a second MSc in Physical and Theoretical Chemistry, obtained in 2022), he integrates computational tools to accelerate and rationalize the discovery of promising lead compounds. Specifically, he uses computational approaches to study chemical reactivity descriptors, molecular modeling, and ADMET properties of biologically active ingredients − all fundamental to drug research. In addition, he employs both theoretical and experimental circular dichroism spectroscopy to assign the absolute stereochemistry of chiral compounds.
