Research Interests

My research, generally speaking, lies at the intersection of statistics and machine learning.

To date this has included topics such as inference methods for big data (especially time series), kernel methods, Markov Chain Monte Carlo sampling, variational inference, and rare-event simulation and probability estimation.

Some of my more recent interests moving forward include:

Deep Probabilistic Programming/Modelling: (in particular with the Pyro language), that is, combining graphical models with deep learning and modern inference techniques.
Deep Generative Models (Flow-Based Models, Diffusion models, Variational Autoencoders, and their generalizations such as Neural Processes).
Representation Learning: How does one represent data in a simplistic way to capture its “essence” and facilitate learning (this includes non-linear approaches to dimensionality reduction and supervised/unsupervised disentanglement).
– The application of, and development of extensions to the above for solving complicated and interesting problems!
