I am a first-year PhD Student in the Economic History department at the LSE. My research interests lie in Economic History, Population Economics, Urban Economics and Political Economy. In my current projects I use large-scale data sources to better understand the economic and political factors that drove demographic change in the 18th and 19th century.
I am a member of the Historical Economic Demography group, and am supervised by Eric Schneider and Tom Raster.
