Hyundeok Choi (NIA)

Title: Research Scientist
Technical Focus Area: Climate Science, Atmospheric Composition, Lidar Science
Study Topics: Atmospheric Chemistry, Troposphere,  Upper Troposphere/Lower Stratosphere (ULTS), Disasters (Volcanoes and Wildfires)


Dr. Choi has a Ph.D. in Civil and Environmental Engineering from Clarkson University in Potsdam, NY, which he received in December 2007. His doctoral research was conducted as a part of a National Science Foundation (NSF) Biocomplexity grant, multi-institutional project, and focused on investigating the mercury input, output, and cycling, and interactions between mercury deposition, emissions and atmospheric conditions. He has been working in the environmental field since he began his undergraduate studies in 1993 at which time he concentrated his academic work in environmentally related courses. Therefore, he has the unique ability to understand the importance and significance of how the environment directly affects human health and welfare. Based on this reflection, he continued studies in environmental engineering, focusing on air pollution and air quality for his graduate studies.
