I am a PhD candidate in American politics. My principal research interest lies in the effects of legislative institutions on individual behavior and collective choice outcomes. My dissertation presents three field experiments on the influence of legislative caucuses on cosponsorship, roll call voting, and bill passage. It focuses on how caucuses support policy expertise and bipartisan behavior. Caucuses illustrate how legislators use informal institutions – those that lack statutory powers – to make informed decisions about politics and policy.
My non-dissertation work includes experimental studies on campaign and media persuasion effects and observational studies on Congressional voting and elections. For more information, please see my CV or research. Please feel free to contact me at apz2002 [at] columbia [dot] edu.
