About
I am a graduate research master's student, co-supervised on Depression Detection from voice signals, by Prof. Prasenjit Mitra and Prof. Rita Singh, at Carnegie Mellon University Africa. Prior to working with Prof. Prasenjit, I worked with Prof. Carlee Joe-Wong of the Learning, Incentives, and Optimizations for Networked Systems LIONS Research group and Prof. Jema David Ndibwile as a Research Assistant on the HumekaFL project, a federated learning system for early detection of birth asphyxia in babies. Over the summer, I was selected among the 1.3% global applicants for the Summer@EPFL program where I interned at the Laboratory for Intelligent Global Health and Humanitarian Response Technologies (LiGHT) lab, supervised by Prof. Mary-Anne Hartley at the School of Computer and Communication Sciences, Ecole Polytechnique Federale de Lausanne EPFL.
