About me:

I joined the University of Edinburgh in October 2016. Before this, I worked as a postdoctoral research associate with Andrew Stuart at the University of Warwick and Max Gunzburger at Florida State University. I obtained my PhD at the University of Bath, supervised by Rob Scheichl.

A more detailed CV can be found here (last updated January 2017).

Research interests:

- Uncertainty quantification in forward and inverse problems
- Bayesian inference for computationally intensive forward models
- Numerical analysis of Gaussian process surrogate models in uncertainty quantification
- Development and analysis of multilevel sampling methods
- Numerical analysis of partial differential equations with random input data
- Multivariate interpolation and integration
