Panayiotis Petousis is a PhD student at the Medical Imaging Informatics Laboratory. He obtain his bachelors and masters in Biomedical engineering from Imperial College London. Earlier research interests and in particular his master thesis involved neural networks and Image Processing techniques mimicking the Human Visual System. Currently, his research interests involve the development of predictive Probabilistic Graphical Models (PGM) from observational clinical data. Additional research interest are the translation of these PGMs in the clinical domain and the visualization of their inferences.
