I have been a Lecturer (~US Assistant Professor) at The Australian National University since February 2015. My research interests are in labor economics and economic history.

Recent projects have focused on the assimilation of immigrants in the 19th and early 20th century United States. Research in this area has been reinvigorated with the mass digitization of historical census files by the fine folks at IPUMS.
