Ignacio Peis

Postdoctoral Researcher


I am a postdoctoral researcher at the Section for Cognitive Systems, in Technical University of Denmark (DTU). I work within Jes Frellsen’s group, where we embark on a range of fascinating projects.

Research   I am interested in the connection between Deep Learning and Probabilistic Modelling. My current research lies in creating more expressive generative models, increasing their robustness (e.g. dealing with mixed-type data or missing data) and developing better inference methods. My work has been applied to several fields, like Neuroscience or Psychiatry.

Previously   I completed my PhD in Probabilistic Machine Learning at Universidad Carlos III de Madrid (UC3M), where I was supervised by Prof. Antonio Artés-Rodríguez and Dr. Pablo M. Olmos from the Signal Processing Group. Previously, I was a research intern at the Machine Learning Group in the Department of the Engineering, University of Cambridge where I worked with Prof. José Miguel Hernández-Lobato. I obtained two MSc degrees in Telecommunications Engineering and Signal Processing from UC3M, and my BSc degree in Telecommunications Engineering from Universidad de Granada (UGR).
