Tanmay A. M. Bharat is a programme leader in the Structural Studies Division of the MRC Laboratory of Molecular Biology. He and his group use electron tomography, together with several structural and cell biology methods to study the cell surfaces of bacteria and archaea. His work has increased the understanding of how surface molecules help in the formation of multicellular communities of prokaryotes, examples of which include biofilms and microbiomes. He has been awarded several prizes and fellowships for his work.
