## About

### Overview

Dr Lara Silvers was awarded a PhD from the University of Leeds in 2004. After a short time as a temporary lecturer at the University of Leeds she became a postdoctoral researcher at UCSD in California before moving to Ecole Normale Superieure (ENS) in Paris. After working at the ENS she became a postdoctoral researcher in DAMTP at the University of Cambridge before taking up a position as a lecturer in mathematics at City in 2009.

### Memberships of professional organisations

- Fellow, The Institute of Mathematics and its Applications, Jul 2018 – present
- Fellow, Higher Education Academy, 2011 – present
- Member, London Mathematics Society, 2010 – present

## Research

Dr Silvers' main research interests lie in the area of Astrophysical Fluid Dynamics and she is particularly interested in understanding interactions between a plasma and a magnetic field in astrophysical objects sun as the Sun.

Her research frequently makes use of computational techniques to solve the governing equations of the system of interest. The numerical solution of these equations is currently carried out at HPC facilities in the UK but previous work has been carried out at facilities in France (IDRIS) and the USA (Teragrid).
