My full name is Konstantinos Christopher Tsiolis, but most people call me by my initials “KC”. I am a first-year Ph.D. student in Statistics at the University of Toronto and the Vector Institute under the supervision of Murat Erdogdu. I am broadly interested in developing a rigorous theoretical understanding of deep learning. More specifically, I seek to use tools from high-dimensional probability to predict the behaviour of stochastic optimization methods.

Previously, I was an M.Sc. student in Mathematics and Statistics at McGill University and Mila under the supervision of Adam Oberman. My thesis research was on contrastive self-supervised learning methods. During this time, I also collaborated with Elliot Paquette on random matrix theory for neural networks.

I graduated with a B.Sc. from McGill in Honours Mathematics and Computer Science in 2021. During my first two summers of undergraduate studies, I was a research assistant at Mila and the McGill Reasoning and Learning Lab under the supervision of Jackie Cheung, where I worked on word embeddings and computational pragmatics.
