Profile

I am a Physicist

About me

Team Player, Innovator, Leader
"How does Nature work?" My drive to find an answer for this fundamental question originally sparked my passion for Physics, and Natural Sciences in general. I like to share this passion with others through teaching and by working in teams. By combining our efforts, I want to lead my team right across the current limit, make the unknown known and innovate through new discoveries about Nature.
