Hyun Kim

Hyun Kim

Hyun Kim, assistant professor of geography, is working on the economic and environmental analysis of the hub-and-spoke network for U.S. air transportation. He recently published a series of articles in highly-rated journals including the Journal of Transport Geography, Journal of Cleaner Production, and International Journal of Applied Geospatial Research.

Kim’s research was motivated by the recent airline mergers among U.S. airline carriers during significant economic downturns in the United States. The research revealed the impact of mergers on passenger levels of service, fuel consumption, and changes in spatial organization of the hierarchy of hubs. To conduct the research, he and his colleagues developed new numerical and statistical methods to measure hub hierarchy.

A Howard H. Baker Jr. Center for Public Policy Research Grant and a UTK Professional Development Award funded Kim’s research. These projects sought to investigate the efficiency and resilience of hub network systems using spatial optimization models and geo-spatial technology.
