Nicklas Hansen

Researcher at UC San Diego

I am currently a researcher in Prof. Xiaolong Wang's lab at UC San Diego. Before that, I was a visiting student at UC Berkeley and a research intern at Berkeley AI Research, where I was fortunate to work with Lerrel Pinto and Xiaolong Wang in Alyosha Efros' group.

I recently completed an MSc in Machine Learning at the Technical University of Denmark (DTU), advised by Ole Winther. I have also been at Nanyang Technological University (NTUsg), Retune-DSP and raffle.ai.

Research interest

I am broadly interested in research on the generalization and adaptation of intelligent systems. I believe AI in the future should be flexible, learn with little supervision, and learn continously over their lifetime. I work with machine learning, robotics, and computer vision.
