Im a PhD student at École polytechnique fédérale de Lausanne (EPFL),though my main workspace is at Idiap Research Institute, where I work as a Research Assistant in the Speech Group, supervised by Mathew Magimai.-Doss. I did both B.Sc. and M.Sc. in Medical Engineering at FAU Erlangen-Nuremberg. During that time, I focused on pattern recognition, hearing and audio research. My Masters"s thesis was on Language Models for Dementia Detection, which I did with Prof. Dr.-Ing. Elmar Nöth at the Pattern Recognition Lab.

Research Interests
The goal of my project is to develop automatic methods that can explain the difference between 'normal'speech and 'atypical'/pathological speech. For that, we currently investigate how to extract representations from speech, that work for classification as well as interpretation, at different granularities, such as sub-word, lexical level and language level.
