Felix Wechsler

About

I'm Felix Wechsler (he/him) and I'm passionate about combining optics with computer science (preferably Julia Lang).

In 2023, I started as doctoral candidate at EPFL in Lausanne in the LAPD led by Christophe Moser. I work on computational tools to improve Tomographic 3D Printing.

Outside of academia, I enjoy cycling (last Mallorca 312 2026) and playing Ultimate Frisbee. Besides that, I'm involved in the Orpheus e.V. to prepare pupils participating at physics competitions. And I'm teaching at the sustainability camp.

Within the EPFL community, I help promote the Julia programming language through the Julia EPFL community.

Don't hesitate to reach out to me (see bottom of this page)!
