Overview & Contact Info
I am a Ph.D. candidate in the Department of Ecology and Evolutionary Biology at the University of Toronto. I am primarily interested in using a deep-time perspective to understand trends in biodiversity and community structure, and the responses of those communities (and the taxa within them) to climate/habitat change. My current research focuses on the use of stable isotope analyses and relative-abundance diversity measures to elucidate some of these patterns in vertebrate communities of the Late Cretaceous of Alberta and their modern analogues in southern Louisiana.
In addition to my doctoral research, I am involved in research on geometric morphometrics and its use in naming species and identifying intra- and inter-specific morphological variation, vertebrate osteohistology and its use in assessing growth and development, biostratigraphy and faunal turnovers, and quantitative evaluations of palaeontological methods and hypotheses.
