## Ndifon, Wilfred

Wilfred Ndifon, a theoretical biologist, has made important contributions to a range of topics at the interface of mathematics and biology including discovering a mechanism that allows influenza viruses to escape from antibodies; a physical mechanism that governs the generation of T-cell diversity via genetic recombination; and a unified mechanistic explanation for both the age-old phenomenon of the original antigenic sin and how antigenic sin is alleviated by vaccine adjuvants. Recently, he led the development of a mathematical approach to pooled testing, which produced substantial testing-efficiency gains in field applications to COVID-19. He took his PhD at Princeton, and is currently Professor and Chief Scientific Officer at African Institute for Mathematical Sciences.
