Junrui (Arielle) Zhang

PhD in Computer Science· University of Toronto | Vector Institute

I'm a first year PhD student in machine learning at the University of Toronto & Vector Institute supervised by Professor Nicolas Papernot.

My work focuses on understanding the training dynamics of large models to improve both capability and safety. I am interested in interpretability, mechanistic understanding, data attribution, and improving LLM's causal inference and reasoning abilities.

Previously, I studied Engineering Science (Machine Intelligence) at the University of Toronto.
