Professor Heeyeun Yoon's research lab specializes in urban sustainability, environmental justice, and the socio-spatial impacts of urban development and environmental hazards. The lab investigates how urban planning policies—such as incentive zoning, green infrastructure, and disaster resilience strategies—affect housing markets, public space accessibility, and environmental health outcomes. Using advanced spatial and statistical modeling, including multilevel and survival analysis, the lab explores the interplay between urban form, environmental change, and community well-being in both U.S. and Asian urban contexts.

This paper empirically tests the extent to which economic restructuring and gentrification affect viability and vulnerability businesses, with specific focus on arts and cultural industries in West Chelsea from 2000 through 2012. Based on the theoretical framework, gentrification stage model and adopting discrete-time survival analysis, we separately compare the risks of opening and closing between businesses established before/early stage of revitalisation (early-arrivers) and those established
In this article, we attempt to examine how privately owned public spaces through incentive zoning have played out as a means to generate public spaces, as part of improving spatial equity in Manhattan, New York City. Using spatial statistical analyses, we find that the inclusion of privately owned public spaces reduces overall average distance to the nearest public space from both working and living population, and helps to balance the distribution of the public spaces throughout the city, by co
In this study, we investigate how far away and for how long past flooding affected single-family housing values in Gyeonggi, South Korea. In order to empirically explore the geographic and temporal extent of the effects, we adopt two analytical methods: random-intercept multilevel modeling and Mahalanobis-metric matching modeling. The analytical results suggest that the geographic extent of the discount effect of a flooding disaster is within 300 m from an inundated area. Market values of housin
Abstract To reduce human exposure to particulate matter (PM), governments have enacted various preventive measures, to which a warning system is central. To the best of our knowledge, we are the first to assess the effectiveness of mobile-based warning systems on respiratory health outcomes, examining two types of <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mrow> <mml:mtext>P</mml:mtext> </mml:mrow> <mml:mrow> <mml:msub> <mml:mrow> <mml:mtext>M</mml:mtext> </
Globally, countries have experienced substantial increases in farmland abandonment. Although vegetation phenology is a key factor for the classification of land use, understanding of the phenological change of abandoned farmland is lacking. Using harmonic analysis of NDVI and NDWI extracted from Landsat imagery, this study investigates the distinctive phenological characteristics of abandoned farmland, which contrasts with that of three other agricultural types (paddy, agricultural field, orchar
