Dimitrios V. Vavoulis

I am a computational biologist at the Department of Oncology and at the Wellcome Trust Centre for Human Genetics, University of Oxford, where I focus on the applications of probabilistic machine learning for the analysis of high-throughput genomic data. I hold a BSc in Biology and an MRes in Environmental Biology with Distinction from the University of Patras (Greece), as well as an MSc in Evolutionary and Adaptive Systems with Distinction and a PhD in Computational Neurobiology (completed under the supervision of Prof. Paul Benjamin) from the University of Sussex. Before moving to Oxford, I worked in the Computational Biology and Bioimaging Group (with Prof. Jianfeng Feng) at the University of Warwick, and in the Computational Genomics Group (with Prof. Julian Gough) at the University of Bristol. The unifying thread underlying my work has always been a keen interest in applying computational methodologies for modelling and data analysis in the Life Sciences.

You can find me online on Twitter and/or Github.
