Vienna → Podersdorf am See, Austria

Andreas Rössler, BSc

I'm a physics student in Vienna, about to move into medical physics research. When I'm not in the lab, I'm out on Lake Neusiedl competing in freestyle windsurfing.

Portrait of Andreas Rössler

I split my year between Vienna and the water. During the semester that's lectures, lab write-ups, and soon medical physics research. In summer it's Podersdorf and Vasiliki — rigging a sail at dawn and trying to land moves I've only pulled off a couple of times.

The two aren't as separate as they sound. Windsurfing is basically fluid dynamics happening in real time — reading gusts, managing lift, controlling a rotation. It's the same kind of problem-solving as physics, just faster, and with worse consequences if I get it wrong.

Studying physics in Vienna

I'm studying physics at the University of Vienna. I wrote my bachelor's thesis on the Milne model, and for the past two years I've been teaching medical physics labs on the side — before starting the Medical Physics programme at the Medical University of Vienna.

Independent projects

Small simulations, built for fun

Computational project

Quantum tunneling through a potential barrier

Solved the time-dependent Schrödinger equation for a wave packet incident on a rectangular potential barrier using a Crank–Nicolson scheme, with the resulting tridiagonal system handled by a Thomas algorithm. Exported the evolution as an animated video.

The actual render — |ψ|² approaching, partially reflecting off, and tunneling through the scaled potential barrier.

Computational project

Heat conduction along a rod

Modeled heat diffusion through a rod — aluminum among other materials — using the method of lines: finite-difference discretization in space, stepped forward in time with explicit Euler integration.

Language: Python Typesetting: LaTeX, used routinely Next up: C/C++ coursework in the master's

Freestyle windsurfing

I compete in freestyle windsurfing on the European circuit. My home spot is Podersdorf am See on the Neusiedler See — flat water and reliable thermal wind, which makes it one of the best freestyle spots in Europe.
