Long-term Sabbatical
During my sabbatical at NESCent, I wish to develop a more comprehensive framework for understanding how and when the community context of a species alters its mode of evolution. To accomplish this goal, I will survey previous literature, generate a conceptual framework, and develop new mathematical models to predict which traits should be most strongly influenced over evolutionary time by species’ interactions.

Princeton University Press This book is intended for undergraduate and graduate students in biology who wish to learn how to develop and analyze their own mathematical models. While at NESCent, I was able to complete the book (finalizing figures, reviewing proofs) and develop the book website (http://www.zoology.ubc.ca/biomath), which includes sample chapters, links of potential interest, and labs for readers to practice the modeling methods described in the book (available for Mathematica). The book is now available for purchase from Princeton University Press.
