Welcome! I am a Postdoctoral Fellow at the University of Pennsylvania and a Ph.D. candidate in Political Science at the University of California, Berkeley. I specialize in comparative politics,  political behavior, and political methodology, with a regional focus on Sub-Saharan Africa.

My dissertation research broadly centers on representation in new democracies, focusing on how political parties and the nature of candidate selection influence the behavior of elected representatives. The fieldwork for this research has been supported by the Korea Foundation for Advanced Studies (KFAS), as well as the Institute for International Studies (IIS) and Center for African Studies (CAS) at UC Berkeley. 

I am also working on a series of research projects on political behavior and identity politics. These include a field experiment on political accountability under a devolved system, a natural experiment to identify the effect of campaign rallies in Africa, a geographic regression discontinuity to examine the relationship between mobile phone coverage and national identity , and a large network survey of political candidates in Zambia.
