I am broadly interested in understanding the evolutionary history and population genetic structure of organisms. In particular, I have investigated the history and structure of several anuran species. However, this research is not limited to terrestrial species as I have also investigated a number of marine taxa. The common theme of this research is to understand how habitat features, historical demography, and geologic features influence connectivity among populations of a species. Recently, this research arm has included the use of ecological niche modeling and landscape genetic approaches to analyze genetic differentiation among populations. Here are some of my publications on these topics:
Torrence, Kathleen, G.**, M.D. Correia, and Eric A. Hoffman. 2012. Divergent sympatric lineages of the Atlantic and Indian Ocean crinoid Tropiometra carinata. Invertebrate Biology 131:355-365
Hether, Tyler D.**, and Eric A. Hoffman. 2012. Machine learning identifies specific habitats associated with genetic connectivity in Hyla squirella. Journal of Evolutionary Biology 25:1039-1052

One particular aspect of a species Evolutionary History that I find interesting is understanding how morphological variation within a species is maintained. Here are some publications on this topic:
Hoffman, Eric A., F. W. Schueler, A. G. Jones, and M. S. Blouin. 2006. An assessment of selection on a color polymorphism in the northern leopard frog. Molecular Ecology, 15:2627-2641
