Overview

Postdoctoral Research Fellow in quantum algorithms with a focus on graph theory in the group of Oleksandr Kyriienko, QuDOS.

I have worked in quantum topological data analysis, entanglement measures, quantum master equations, graph theory in wave scattering, exceptional points in several settings, and spin dynamics. I always approach problems with an eye to interdisciplinarity by training.

Fedora and Vim user, Julia coder, audiophile. I have been a carpenter, CNC guru, and CAD/CAM dev. Into specialty coffee, I did skydiving, a 2000 Km bike trip across Europe, and piloted a wartime fighter aircraft. After I drink my coffee, I can also do other things, mainly playing tennis, climbing, motocross, and gaming. I am an adrenaline junkie in life and I strongly believe in hands-on experience.
