Dr Andrzej Harris

Subject: Natural Sciences
Tutor; Postgraduate Tutor (Welfare)
Research Associate

After completing his PhD in Biological Science at Corpus Christi, Dr Harris joined the MRC Laboratory of Molecular Biology at the University of Cambridge as a Postdoctoral Fellow, specialising in cryo-EM reconstruction of bacterial protein filaments involved in cell division and plasmid DNA segregation. During this time, he was a Teaching Associate at St Catharine's, supervising the College's medical and veterinary undergraduates.

Since 2018, Dr Harris has been a Research Associate in the University's Department of Biochemistry, where he is applying his cryo-EM expertise to the reconstruction and computational modelling of antibiotic transport by bacterial tripartite efflux pumps and related membrane proteins.
