About
Daniel Roy is a Canada CIFAR AI Chair at the Vector Institute, an associate professor in the department of statistical sciences with a cross-appointment in the department of computer science and electrical and computer engineering at the University of Toronto. He is also an associate professor in the department of computer and mathematical sciences at the University of Toronto Scarborough.
Roy’s research blends computer science, statistics and probability theory. He studies probabilistic programming and develops computational perspectives on fundamental ideas in probability theory and statistics. He is particularly interested in representation theorems that connect computability, complexity, and probabilistic structures, stochastic processes, the use of recursion to define stochastic processes, and applications to nonparametric Bayesian statistics, and the complexity of probabilistic and statistical inference, especially in the context of probabilistic programming.
