From Quantum Physics to Code

When I was young, I came across "Knaurs Buch der modernen Physik" and spent months trying to decipher every page. It sparked a fascination that carried me all the way to a PhD in theoretical physics — and in hindsight, it was absolutely worth it. Quantum mechanics in particular hooked me; focusing on the computational side helped me stay grounded. What you can build, you can understand — and there are plenty of unsolved mysteries that don't require philosophical treatment, just fast computers and good models. During my PhD I pursued a novel way to simulate interacting many-body systems. After that I spent a good deal of time teaching, which I loved — not only for the students themselves, but because communicating physics clearly forced me to refactor my own knowledge.

Hitting the Metal

While writing physics simulation programs I discovered a genuine passion for clean software design — maybe because decomposing a complex physics problem into its parts isn't so different from decomposing a complex software project into modules. Clear interfaces, clear responsibilities, composing something intricate from well-defined pieces. Something pulled me toward embedded software development: I wanted to go deep and low-level, to feel the hardware. Among other things, I implemented security protocols across all levels of the Ethernet stack — TLS, IPsec/IKE, MACsec/MKA — for automotive ECUs, shipped in many cars worldwide.

From ECUs to Agents

Alongside this, I studied computer science. It reshaped how I think about science and shifted my focus toward agentic and physical AI. The substrate differs, but the challenge is familiar: building systems that fail gracefully, recover predictably, and behave reliably under uncertainty — whether the medium is a deterministic ECU or a non-deterministic AI agent. A new engineering discipline is emerging around making agentic systems (physical and digital) trustworthy and reliable, and it is a domain where I intend to focus my work.
