Bio

I am currently a Senior Researcher at the Data Science Group, Institute for Basic Science, South Korea. I am currently working towards applying AI-based methods for Protein and Antibody Design applied to drug discovery. I am also interested in improving exploration and credit assignment in single-agent and multi-agent reinforcement learning. My main research interests involves Deep Learning, Reinforcement Learning, and Bioinformatics. I have previous research experiences in Deep Reinforcement Learning applied to Robotics (continuous control, development of simulated environments, multi-agent systems), Speech Synthesis (corpus building and segmentation, statistical parametric speech synthesis), and Natural Language Processing (using sequence-to-sequence models and transformers). My personal interests include traveling, sports (football, kickboxing, skate, surfskate), music (classical guitar, cavaquinho) and reading (fantasy, science fiction, mountaineering).
