Lazar Atanackovic

I am a Ph.D. Candidate at the University of Toronto in The Department of Electrical & Computer Engineering and the Vector Institute.


I am a member of the Probabilistic and Statistical Inference Group supervised by Brendan Frey and co-supervised by Bo Wang. Previously, I was a machine learning research intern at Recursion Pharmaceuticals / Valence Labs and a research intern at MILA.

My research focus is in developing machine learning methods for deciphering and modelling cell dynamics from data. I am interested in generative modelling, dynamical systems, structure learning / causal discovery, and computational biology.
