EPPENSTEINER

I like doing both: running simulations and working in the lab. And because I trained in graphic design, I also care about how the results are presented.

What I've built

Hand-soldering the driver board at a workbench

Constant-current driver for a diode laser

A constant-current driver for a 450 nm laser diode. I worked out the circuit, simulated it in LTspice to check it, and then soldered it by hand on a perfboard.

What I compute

With density functional theory (DFT) you can calculate what happens at a catalyst, even where experiments can't look.

Catalytic mechanisms of indium-oxide clusters for methanol synthesis

bachelor thesis · university of innsbruck · 2026

To turn CO2 back into methanol, you need a catalyst that can break up a very stable molecule. Indium oxide can do that, but the reaction is too fast and too small to observe directly, so you have to calculate it.

In my bachelor thesis I used DFT to calculate where CO2 and H2 bind on In2O3 clusters, which bonds break first and how much energy each reaction step needs.

How I got here

My education as an energy-level diagram. Every step up took a few years of work.

since feb 2026

Where I've worked

internships

jul – sep 2026

VDSP summer internship

University of Vienna

I worked on abTEM, an open-source Python package that simulates electron microscopy images. My part was adding VASP as a source for the electrostatic potentials. I tested it on hBN, SrTiO3 and MoS2, three materials that scatter electrons quite differently.

jul – sep 2024

Energy Solutions internship

Innio Jenbacher

I analysed software processes in engineering and product development and documented steps that had never been written down before.

jul – aug 2023

Ion and Plasma Physics internship

University of Innsbruck

Hands-on work in an experimental group. I helped set up measurements and take data.

alongside my studies

since jan 2020

Blood donation service, part-time

Austrian Red Cross, Innsbruck

I maintain the donor database and look after first-time donors, who are often a bit nervous before their first donation.

voluntary work

2022 – 2024

Campus Tirol Motorsport

Formula Student team, Innsbruck

I built aerodynamic parts for the team's car, for example the carbon endplates for the Aeris.

Fitness instructor for seniors

Strength classes

I plan and lead a weekly strength class for a group with very different fitness levels.
