# Tanmay A. M. Bharat

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.

## Education

Bharat graduated with a BA in Biological Sciences from the University of Oxford, UK. His studies were supported by a Rhodes Scholarship. He then undertook research at the European Molecular Biology Laboratory in Heidelberg, Germany for his PhD working with John A. G. Briggs. He studied the structure and assembly of pathogenic viruses using cryogenic electron microscopy and tomography. His work on several viral capsid proteins improved understanding of how viruses are assembled within infected cells.

## Research

He subsequently joined the MRC Laboratory of Molecular Biology (LMB) in Cambridge to pursue post-doctoral research with Jan Löwe using cryo-EM to study proteins within bacterial cells. After his post-doctoral appointment concluded, he was recruited to the Sir William Dunn School of Pathology, University of Oxford as a Wellcome Trust and Royal Society Sir Henry Dale Fellow. After obtaining tenure at Oxford, he moved back to the LMB as a programme leader in 2022. His research investigates how bacteria and archaea use their surface molecules to form multicellular communities. For instance, during human infections bacteria form biofilms that help them evade antibiotics. The group also use electron tomography.
