Research interests

My research has been funded by the National Science Foundation (NSF), among other sources, and primarily falls within two core subfields of political science: international relations  and political methodology.  Within international relations,  research political violence, environmental politics, and international political economy. My methodological work draws upon these substantive interests with a focus on computational social science techniques, duration modeling, and  finite mixture models for the study of political science.

This research page organizes my published and ongoing research projects into the subcategories described above. Note that several of my projects appear in multiple subcategories below. For a single itemized list of my publications, please see this page.
