πŸ‘‹ Hi, I'm Costa, a Computer Science Ph.D. student at Drexel University studying Game Artificial Intelligence. I enjoy doing research and conducting super cool experiments!

I use Deep Reinforcement Learning (DRL) to train computer agents to walk, hop, or even play an Atari 2000 game!

The best performing agent after 4 hours of training. Yeah, it's difficult to learn to walk like humans.

Our trained agent (the green player) learned to win consistently in Pong!

My more recent work focuses on scaling DRL to Real-time Strategy (RTS) games, in collaboration with my advisor Santiago OntaΓ±Γ³n.

Let's safely land our shuttle to the lunar surface. Gotta be steady and precise!

Have some fun with a car racing game!

A simulated RTS game. The white, green block and circle are bases, resources and workers. The purpose of the game is to gather resources, build an army and destroy enemy forces.

You can easily use my DRL library CleanRL to train the agents to play all of the games above.
