Mélanie Roschewitz, PhD

About me

I’m an ML researcher interested in the safety, reliability and fairness of AI systems for healthcare. I’m currently as postdoctoral fellow at the ETH AI Center, working with Profs. Julia Vogt and Michael Moor. Previously, I did my PhD at Imperial with Prof. Ben Glocker.

Background

I started my studies with a B.Sc. in Mathematics as well as a postgraduate diploma in Statistics from the University of Strasbourg (France). Later, I graduated from ETH Zurich with a M.Sc. in Data Science, focusing on medical applications of machine learning. I then joined Microsoft Research Cambridge (UK), where I was an Applied Researcher in their medical imaging team, focusing on developing ML models for personalized treatment as well as on open-source efforts in ML for healthcare. In October 2021, I then started my PhD at at Imperial College London, advised by Prof. Ben Glocker, graduating July 2025. During my PhD, I was a 2024 recipient of the Google PhD fellowship in Health & Bioscience and of the Imperial College President’s scholarship. And I also joined the Kheiron Medical Technologies ML research team for an internship from April to October 2022.
