African Institute for Mathematical Sciences

Wilfred Ndifon is Professor of Theoretical Biology and the Chief Scientific Officer at AIMS, a Pan-African network of higher-education institutes dedicated to catalyzing Africa’s socio-economic transformation through advanced training and research in mathematical sciences.

He has made important contributions to a range of topics at the interface of mathematics and biology, including discovering a mechanism that allows flu viruses to escape from antibodies, with significant implications for the design of more effective flu vaccines; a physical mechanism that governs the generation of T-cell diversity via genetic recombination; and a unified mechanistic explanation for the age-old problem of the original antigenic sin. Recently, he led the development of a new mathematical approach to pooled testing, which has produced substantial testing-efficiency gains in field applications conducted in both Rwanda and South Africa. He took his PhD at Princeton.
