Research Interests and Project Expertise
Geographic Harmonization; International Census Data; Geographical Information Systems (GIS); Historical Demography
My association with MPC begins in 2001, when I started working as a graduate research assistant on the National Historical GIS project while pursuing for a degree in geography at the University of Minnesota. After completing my PhD in 2006, I became a full-time employee working on international microdata projects - NAPP and IPUMS-International and more recently Terra Populus and IDHS.
As a geographer, I study the changing administrative boundaries from one census year to another. My work at MPC mostly deals with harmonizing this changing geography in different countries. Besides administrative boundaries and microdata, I produce GIS maps that can be used for mapping and visualizing IPUMS-International and Terra Populus data. I also work with the IDHS project, creating consistent geography variables. My work at MPC fits well with my research interests - visualization of census microdata from several countries. I mostly focus on migrants and immigrants and use GIS as a tool for visualization.
