Scholarly Areas: Dr. Eunha Hoh’s research interests focus on the investigation of diverse environmental pollutants in the environment and their impact on food safety and human health. Analytes of interest are known toxic organic pollutants such as persistent organic pollutants (POPs) and polyaromatic hydrocarbons (PAHs), as well as potentially toxic brominated/chlorinated flame retardants, their degradation products, and other emerging contaminants. Dr. Hoh recently developed an untargeted analytical approach for detection of a broad range of organic chemicals in fish oil using novel instrumentation. Using this approach, she discovered and identified previously unknown halogenated compounds including naturally occurring halogenated products and other contaminants in fish oil. She is working on further development of this untargeted analytical approach and its application towards various types of samples for environment monitoring and food safety. Most of her work involves the application of chromatography and mass spectrometry.
Research Support:
Biography: Dr. Eunha Hoh joined SDSU in the spring of 2009 as a Tenure-Track Assistant Professor in the Occupation and Environmental Health Division in the Graduate School of Public Health. Dr. Hoh received her doctoral degree in Environmental Science in 2006, under the guidance of Distinguished Professor Ronald A. Hites at Indiana University. Her research focused on the fate and transport of organohalogen contaminants in the atmosphere and the investigation of previously undetected halogenated flame retardants in the environment. After her graduation, she worked as a postdoctoral researcher in the field of food safety at the USDA Agricultural Research Service, Eastern Regional Research Center, located near Philadelphia, PA. She developed novel analytical methods which included fast and efficient analyses of multiple classes of targeted chemical residues, and an untargeted analytical approach for organic compounds of interest in food and environmental samples. Prior to pursuing her degree in Environmental Science, she received a master’s degree in Chemistry at the Korea Advanced Institute of Science and Technology in South Korea and worked in industry.
