I am currently an Associate professor at UNR, where I joined as an Assistant Professor in 2014. Before that, I was an Assistant professor at UC Riverside from 2007 to 2014. I completed my PhD at the University of Arizona in 2007, supervised by Ronald Oaxaca and Price Fishback.

I am a labor economist. My two main areas of research are imperfect competition in labor markets, immigration and the intersection of these two issues.

My favorite part of being an academic is the ability it affords me to travel; I have now presented my research at universities in 15 countries.
