I am a Validation Engineer at Quantum Machines, where I work at the intersection of quantum control and engineering, helping to build robust and reliable quantum computing control systems.
Previously, I was a Metrologist at Advantest, specializing in reliability engineering and electromagnetic compliance for automated test equipment.
Before that, I pursued a Ph.D. in Physics at the Nanoscale Science Department of the Max Planck Institute for Solid State Research, advised by Klaus Kern and Klaus Kuhnke. My research focused on understanding the fundamental dynamics of luminescence processes at the single-molecule scale, with a focus on nanooptics, scanning probe microscopy, and exciton-plasmon interactions.
