Tomasz has obtained a MSc in Machine Learning from University College London, and then a PhD in Physics and Astronomy from the same university. Then he moved to ETH Zurich Cosmology group, where he worked on data science problems in measurement of cosmological parameters using large telescope surveys. He was a PI of "Deep Learning for Observational Cosmology", an SDSC project in the first call for proposals. He worked extensively on introducing deep learning and generative machine learning methods in cosmology.
