About Me

Hi! I’m Alizée, a PhD student in Machine Learning and a fellow at the ETH AI Center in Zürich. I am lucky to work with Prof. Gunnar Rätsch and Prof. Bernhard Schölkopf. I am also part of the ELLIS PhD program. My main research goal is to develop ML solutions for clinical decision support and personalised treatment recommendation, with an interest for offline reinforcement learning, representation learning and causal inference.

I am an incoming student researcher at Google Zürich, working with Aliaksei Severyn on RL methods to improve LLM training.

Before my PhD, I led a project on imitation learning for clinical decision-making with Prof. Mihaela van der Schaar at the University of Cambridge. My professional experience also includes medical device development for stroke treatment, sensor-assisted surgery and 3D-printed heart stents, as well as software engineering at CERN. In parallel, I studied Physics, Materials Science and Machine Learning at Cambridge, where I consistently ranked first in my year.

Professional Experience

Doctoral Research Fellow
Sep 2021 – Present Zürich, Switzerland
My main research goal is to develop ML solutions for clinical decision support and personalised treatment recommendation in the intensive care unit. General areas of interest include offline reinforcement learning, representation learning, causal inference and time-series modelling.
Research Assistant - Clinical Imitation Learning
Mar 2021 – Sep 2021 Cambridge, UK
Research project on interpretable imitation learning for clinical decision support. Our goal was to describe and understand treatment or diagnostic policies through novel decision tree models, and capture how decision-making behaviour varies over time with patient information. Publication accepted as Spotlight for ICLR 2022 (5% acceptance rate).
Research Assistant - Bioelectronics
Sep 2019 – Mar 2020 Cambridge, UK
Research project on printed biocompatible force sensors for orthopaedic implants. Resulted in two publications (1 and 2).
R&D Engineering Intern - Medical Device Data Analysis
Jul 2019 – Sep 2019 Barcelona, Spain
Development of a new thrombectomy device which restores blood flow in stroke patients. Resulted in three patent applications (1, 2 and 3)
Research Assistant - 3D-Printing and CT Imaging
Jun 2018 – Aug 2018 Cambridge, UK
Optimised the 3D-printing technique for biodegradable heart stents.
Software Development Intern
Aug 2016 – Aug 2016 Geneva, Switzerland
Development of Invenio user interface and of demos for a reproducible analysis platform.
Programming Teaching Assistant
Jan 2016 – Sep 2016 Lausanne, Switzerland
Selected to write a 85-page book of lecture summaries for a C++ object-oriented programming course.
