Seungjae (Jay) Lee

I am a Ph.D. student in the Department of Computer Science 💻 at UMD, where I am fortunate to be co-advised by Prof. Furong Huang and Prof. Jia-Bin Huang.

Prior to joining UMD, I earned my Master's degree in the Department of Aerospace Engineering ✈️ at SNU, where I was fortunate to be advised by Prof. H. Jin Kim. I also had the privilege of working at the Generalizable Robotics and AI Lab (GRAIL) 🤖 at NYU under the guidance of Prof. Lerrel Pinto.

Before that, I received Bachelor's degrees in Mechanical and Aerospace Engineering at SNU ⚙️.

"💻 + ✈️ + 🤖 + ⚙️ = Me"
