Nicolas Ugrinovic

I am a Postdoctoral Researcher at Carnegie Mellon University, where I work with Kris Kitani. Previously, I worked at Meta (FAIR).

I obtained my PhD from IRI-UPC under the supervision of Francesc Moreno-Noguer and Alberto Sanfeliu. During this time, I interned at Amazon Science with Alex Vorobiov. I was also a visitor at Stanford University in Leonidas Guibas Lab and Naver Labs Europe with Gregory Rogez.

My research is in areas of computer vision and machine learning, specifically on 3D human pose/motion estimation, human motion generation, and reconstruction of 3D bodies.
