Yijie Li

Research Assistant
Robotics Institute
Carnegie Mellon University, Pittsburgh, PA

I am a Research Scientist at Black Sesame Technologies Inc. During Jan 2025 - Aug 2025, I was a Research Assistant at Robotics Institute, Carnegie Mellon University, advised by Prof. László A. Jeni. I earned my Master’s degree in Artificial Intelligence at Northwestern University. Previously, I received my Bachelor’s degree in Software Engineering from University College Dublin (UCD) in July 2023.

I was a research intern at Tsinghua University in 2022~2023, focusing on generative adversarial networks (GAN), advised by Prof. Yongjin Liu. Before that, I was working on several topics related to computer vision, supervised by Dr. Soumyabrata Dev at UCD.

My research interests lie in Machine Learning and 2D/3D Computer Vision, including efficient neural networks, human motion recovery, and generative models.
