work

Most recently I was a Research Fellow at Harvard University's CSElab (2025), where I developed computational models for combustion, turbulence, and fluid flows, including reinforcement-learning approaches for CFD.

Before that I worked on regeneratively cooled satellite thrusters at the German Aerospace Center; cooling-channel design at Imperial College London Rocketry; a 4 kN hybrid-rocket test system with Space Team Aachen; and EUV Lithography at TOS at RWTH Aachen.

research

My recent published research looked at nanosecond-pulsed plasma ignition of ultra-lean hydrogen-air mixtures: how discharge energy, frequency, and pulse count change whether a mixture ignites reliably.
