Introduction I am a senior research scientist at NVIDIA working on machine learning and computer vision. I am a member of the NVIDIA Toronto AI Lab (Canada) led by Professor Sanja Fidler. I received a PhD in Computer Science from Université Pierre et Marie Curie (now Sorbonne Université in Paris, France) in 2015. My doctoral supervisors were Professor Matthieu Cord and Professor Stéphane Gançarski, I was also supervised by Professor Nicolas Thome. I was a visiting research scholar in the team of Professor Eric Xing at the School of Computer Science, Carnegie Mellon University in 2015~2016. From 2016 to 2019, I was a postdoctoral fellow in the Department of Computer Science (Machine Learning group) at the University of Toronto and Vector Institute under the supervision of Professor Raquel Urtasun and Professor Richard Zemel.
Research Interest My main focus is to propose scalable machine learning methods that can be applied to computer vision tasks.
More specifically, my domains of interest are: distance metric learning, complex representations including hierarchies and graphs, differential geometry, algebraic topology, convex and non-convex optimization, optimization on manifolds, information geometry, structured output prediction, generalization with limited supervision including few-shot learning, semi-supervised learning, active learning, domain adaptation and self-supervised learning.


Graduate and senior (third- and fourth-year) undergraduate students interested in doing an internship in the NVIDIA Toronto AI Lab can directly send me their resume.
