About

Hi there! – I’m Lewin, owner of this little website.

Born in 1996, I joined Google in Zürich (Switzerland) after finishing high school, and worked for four years as a Systems Engineer in Site Reliability Engineering (sre.google). There, I took care of Google Docs, Google Drive, and later, Borg – the global computing grid that all of Google runs on. I managed to be promoted to Senior Systems Engineer within that time, and while it was my dream job, I left it in 2018 – to fulfill my long-held dream of studying physics.

At RWTH Aachen, in the very west of Germany, I’ve enjoyed not only a challenging education, but also a multi-disciplinary environment, allowing me to work on projects like robotics software (at IGMR), literal Space Lasers (MERLIN, at Fraunhofer ILT), and teaching Python to other students. Most recently, I worked in Prof. Goettsche’s group on Nuclear Verification and Disarmament (NVD), where I extended my bachelor’s thesis and investigated the applicability of Automatic Differentiation (AD) for simulation applications in nuclear weapons & peace research.

2021 to 2023, I was enrolled in the Physics master’s program at RWTH Aachen. I took the Nanoelectronics track, combining condensed matter physics with information technology. My studies were partially funded by the German Academic Scholarship foundation, the most prestigious scholarship program in the country.

In 2022, I’ve spent a few months in California at UC Davis. This stay was funded by the Studienstiftung. Right after, I started working on my master’s thesis on Silicon Integrated Photonics for WDM in Cryogenic Environments under Prof. Leuthold (ETHZ, Institute of Electromagnetic Fields IEF) and Prof. Barends (FZJ) at ETH Zürich, finishing my degree in fall 2023. Silicon photonics is a fascinating area, and I am fortunate enough to have had a project covering the whole process: from device calculation, design, simulation through fabrication in a cleanroom all the way to characterizing the devices. The results of my work may one day be used in quantum computers for delivering signals to qubits.

Since fall 2023 I’ve been working in industry, at Zurich Instruments AG in (guess what) Zürich. ZI is a subsidiary of Rohde & Schwarz (Munich), and develops high-end digital lock-in amplifiers, impedance analyzers, and quantum computing control systems. I’m working on the latter, ensuring that the next scale-up steps in quantum computing will be achieved. Day-to-day, this involves high-performance networking software in C++ and Rust, covering large parts of the quantum computing stack.

When not busy at work, I like going out for hiking, cycling, and paragliding - the three best ways to explore the mountains, in my opinion! If I take along my camera, you can see the results in the photos section.
