I am an associate professor in the Department of Statistics at The Ohio State University. My research interests include uncertainty quantification and statistical inverse problems.

I joined the department in 2014, after finishing my PhD in the Department of Statistics & Actuarial Science at Simon Fraser University in Burnaby (British Columbia, Canada), advised by Dr. David Campbell. This is where I became interested in inference and uncertainty quantification for complex systems. Before that I studied nonparametric smoothing methods, advised by Dr. Natalia Stepanova in the School of Mathematics and Statistics at Carleton University in Ottawa (Ontario, Canada). I have also worked as a researcher for the Government of Canada.
My research is in the areas of uncertainty quantification and stochastic computation. I am interested in developing methodology for state and parameter inference for dynamical systems models, such as those defined by ordinary and partial differential equations, stochastic differential equations, and other stochastic generative models. Another focus of my research is in relating error models for numerical methods to probability models of epistemic uncertainty. In particular, I have been working on probabilistically characterizing discretization uncertainty associated with finite-dimensional representations of the solution of nonlinear differential equations. This research area lies at the interface between statistics and numerical analysis.
