Vianey Leos Barajas is an Assistant Professor, cross-appointed between the Department of Statistical Sciences (51%) and School of the Environment (49%) at the University of Toronto. She is primarily interested in working in the areas of ecological statistics, time series modeling, Bayesian statistics and, more recently, spatial modeling of environmental data.

Vianey is currently a Faculty Affiliate of the Vector Institute and a Faculty Member of the Centre for Global Change Science at the University of Toronto. Additionally, she is serving a 2-year term on the Stan Governing Body and am the current secretary of the Statistical Ecology section of the Ecological Society of America.

Collaborative projects bring her loads of joy. So, while she is formally trained in mathematics and statistics, Vianey is likely to be working closely with ecologists (esp. those who work with sharks) often and on many projects.
