About
Using optics and computation to solve problems in medicine.
I'm a PhD candidate at the Laboratory of Physics of Interfaces and Thin Films (LPICM), École Polytechnique, where my work centres on building real-time polarimetric imaging systems for biomedical applications. My research spans polarimetry, optics, physics-informed machine learning, and clinical translation — with a current focus on intraoperative tumour delineation during brain surgery.
Before my PhD, I completed a Master's in Artificial Intelligence focused on biomedical applications, and a Master's in Economics specialising in Health Economics. I also spent time at EY. I work well at the edges between disciplines — translating between physics, computation, economics and clinical practice is where I find my most interesting problems.

Outside the Lab
When I'm not in the lab, I enjoy running. I've completed a 100-mile ultramarathon and a 140 km backyard ultra (track format), and I aim for at least one marathon and one ultramarathon per year.
I sometimes post running things and personal updates on Instagram @chaetries.
