Recent News

  • (Online Course in July) I will be teaching the second half of the course “Neural Networks and Related Models” at the (fully online!) AMSI Winter School in July 2021. Here, my portion is the “related models” which will include interesting probabalistic and generative models such as Variational Autoencoders, Normalizing Flows, and Generative Adversarial Networks.
  • (Paper Accepted)  2nd June, 2021. The (minor) revision of  work Implicit Langevin Algorithms for Sampling From Log-concave Densities has been accepted for publication in the Journal of Machine Learning Research (JMLR) and will appear in the near future.
  • (New Paper) 5th April, 2021. Preprint “Spectral Subsampling MCMC for Stationary Multivariate Time Series” is now available. Here, we show how to accelerate Bayesian inference with MCMC on “big data” time series in the multivariate case. This extends upon our ICML paper which focused on the univariate case.

Research Interests

My research, generally speaking, lies at the intersection of computational statistics and probabilistic machine learning. I am broadly interested in these fields, but specifically I am particularly interested in developing novel methodology and theory relating

  • Inference Algorithms  (e.g., Markov Chain Monte Carlo, Sequential Monte Carlo, and Variational Methods)
  • Kernelized Stein Discrepencies
  • Deep Generative Models (e.g., Normalizing Flows and Variational Autoencoders)
  • Variance Reduction and Unbiased Estimation  in Monte Carlo Simulation
