Dr Philipp Thomas is a Lecturer in Biomathematics. He has recently been awarded a UKRI Future Leaders Fellowship. Previously he was a fellow for the Royal Commission for the Exhibition of 1851. He received a PhD in Applied Mathematics from the University of Edinburgh in 2015. He also serves as an associate editor for Scientific Reports.

Our group develops stochastic methods to understand single cell dynamics and cell-to-cell variability in biological populations. See our group website for details.

We have an open postdoc position (see also and naturecareers)! Please get in touch informally via email.
