Students interested in working on a PhD project (to start in September 2017) in the areas of:

- stochastic partial differential equations,
- non-linear partial differential equations,
- stochastic control theory,
- computational methods and applications of the above (in engineering, biology, finance, ...)

See the School PhD applications website for more details regarding applications. Funding is available either through the School or via the Maxwell Institute Graduate School in Analysis and Applications (MIGSAA).

Here are some events I am (or was) helping to organize.
