School of Mathematics & Statistics

I am a Lecturer (tenure track assistant professor) in Data Science in the school.  My broad research interests lie in the theory and application of data science methods.  One of my overarching goals is to develop stronger connections between the mathematical & statistical foundations of data science methods and their applications.  I am motivated by 1) how applications can inspire new theory and 2) how theory be developed in a more practically relevant way.              

My research has primarily focused on 1) Monte Carlo methods for sequential Bayesian inference in continuous and discrete time; 2) stochastic analysis of McKean-Vlasov type non-linear filtering methods 3) methods for quantifying model uncertainty from data and 4) real-time estimation of non-stationary model parameters.  I am particularly motivated by applications in the environmental and biomedical sciences.
