Timothée Poisot (but please call him Tim) is an assistant professor at the Université de Montréal. According to his website (http://poisotlab.io), he does research in computational and quantitative ecology. This means that he hates going in the field, and uses maths and computers to do ecology instead (but some of his best friends are empiricists!). Tim works primarily on the variability of species interactions, and the role of species interactions in driving ecosystem functions. Be prepared for lots of discussions about the relationships between theory and field work in ecology, the culture of data sharing, and what it means to be a new faculty.
