Fidel I. Schaposnik Massolo

I am a high-energy physicist working as postdoctoral researcher at Institut des Hautes Études Scientifiques (France), and previously at Université Libre de Bruxelles (Belgium) and Institute for Basic Science (South Korea). I am interested mostly in holography and low-dimensional models of quantum gravity, although I have also been known to work in condensed-matter physics, slime mold models and other interdisciplinary topics. During the last few years, I’ve been working on artificial intelligence for automated theorem proving with Vasily Pestun. For more details, you can check out my publications page or see my full CV here.

I began programming in the early 2000’s when I discovered then-little-known Python 1.6 through a family friend, and have been coding ever since – my SourceForge account is now old enough to drink! My preferred languages are Python for machine-learning and artificial intelligence, as well as day-to-day automation; C++ for competitive programming; and Mathematica for symbolic computations and Physics projects.

Apart from my programming habit, I enjoy cooking and running (let me know if you happen to be around and want to go for a jog :-)

If you came here looking for a different person chances are you are after my father, who is coincidentally also a physicist and named Fidel Schaposnik. You can check out his website here, and you should also take a look at Laura Schaposnik’s website, who is my sister, a Mathematician and publisher of a collection of children’s books.
