## 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.

## Research

### Research Interests

My main research interests lie in the area of Astrophysical Fluid Dynamics and I am particularly interested in understanding interactions between a plasma and a magnetic field in astrophysical objects such as the Sun. My research frequently makes use of computational techniques on high performance computing facilities to solve the governing equations of the system of interest.

### Current Research

At present I am primarily focussed on a challenging research theme of the impact of temperature-dependent transport coefficients when modelling the solar interior. This research is being undertaken using a combination of analytic and numeric techniques.

### Recently Completed Projects

A large body of research that has recently been completed focussed on understanding shear flow instabilities in compressible fluids. This research was conducted to obtain a deeper understanding of the solar tachocline, which is part of the solar interior where there is strong shear.

This research has led to a number of publications and the full details of these are given in my publication list.
