I am an Applied Scientist at Amazon, where I develop novel methods in machine learning and statistics, and apply them to practical problems. My research interests lie in probabilistic machine learning, and especially in the intersection of deep learning and Bayesian inference. I have previously worked on normalizing flows for generative modelling/density estimation, and Bayesian inference for robust predictive models.

I received a PhD in Machine Learning from the School of Informatics, University of Edinburgh, where I was supervised by Iain Murray. During my studies I completed an applied machine learning internship with Amazon (Berlin), and a machine learning research internship with Google Research (Zurich), where I worked on generative modelling of human motion with normalizing flows.

For my MSc thesis I worked on generative video modelling via latent space transitions. Before diving deeper into machine learning, I worked on recommendations at Amazon (Edinburgh) and studied Computer Science at the University of Manchester, where my final-year project was on evolutionary computation.
