I am a PhD student at the Robotics Institute of Carnegie Mellon University, advised by Prof. Katerina Fragkiadaki. Previously, I received my M.Sc./B.Sc. Diploma in Electrical and Computer Engineering from National Technical University of Athens in Greece, where I also spent 2 more years working with Prof. Petros Maragos.

Before joining CMU, I worked as an ML Engineer/Researcher at Deeplab on Scene Graph Generation. Before Deeplab, I also worked at METIS Cybetechnology as an AI Engineer on Natural Language Processing systems.

Beyond Projects

game While teaching myself the drums, I applied the same top-down strategy I learned through my professional and academic experience. I went straight through the basics to play real songs and this site helped so much that I wanted to contribute. I often found myself bound to clear unreadable drum tracks before manually transcribing the correct notes and as usual in such cases, some programming saves the day! I built some simple functions to instantly clear and reorganize drum tracks so that they are readable and (at least ergonomically) playable.
