Benjamin Dalziel
Assistant Professor

I have broad interests in ecological and evolutionary dynamics, particularly related to the health of human and animal populations, and to the maintenance of biodiversity.

I am particularly interested in (i) the ecology and evolution of infectious diseases, especially the impact of host population structure on pathogen spread and diversification and (ii) how animal movement shapes ecosystems, particularly how collective behavior affects trophic interactions and ecosystem stability. 

To address these questions I work with students and collaborators at the interface of mathematical models and empirical data. Some recent work is listed below, and more can be found on my Google Scholar page.  A website is also in the works, so check back soon!
