Junghwan Kim (advisor: Mei-Po Kwan) earned First Prize in the Race, Ethnicity, and Place 2020 Conference Student Research Presentation Competition. His doctoral dissertation paper entitled "How Neighborhood Effect Averaging Might Affect Assessment of Individual Exposures to Air Pollution: A Study of Ozone Exposures in Los Angeles", has been recently published in the Annals of the American Association of Geographers.

Kim's paper provides an in-depth examination of the neighborhood effect averaging problem (NEAP) and how the NEAP is associated with people’s daily mobility through an assessment of individual exposures to ground-level ozone using the activity-travel diary data of 2,737 individuals collected in the LA metropolitan statistical area.
