I am Geographer at International Programs Center of the U.S. Census Bureau and received Ph.D. in Geography & Urban Regional Analysis from UNC Charlotte.
My research area is economic geography and transport geography. I am interested in spatial interaction and the formation of spatial organization in diverse geographical scale, from neighborhood to global scale. I currently study the geography of global trade flow, especially examining containerized export shipping records to see the economic regionalization and shrinkage of space under global spatial interaction.
I also have a deep interest in developing spatial econometric methods. I focus on improving estimation of spatial econometric models in small areas under data uncertainty.
Outside of my research, I usually go hiking and travel cities in different countries. I also enjoy reading philosophy books and discussing politics and societies with friends with aromatic tee or coffee, or sometimes, pints of beer.
