Georg E. Matt, PhD

Professor of Psychology

More About Dr. Matt

Dr. Matt is a Professor of Psychology in the College of Sciences at San Diego State University and a participating member at the University of California San Diego Moores Cancer Center. Dr. Matt’s research focuses on human exposure to tobacco smoke toxicants in real-world field settings and on strategies to protect nonsmokers from the exposure to tobacco smoke toxicants from secondhand and thirdhand smoke. 

Dr. Matt is the PI of the Thirdhand Smoke Dissemination, Outreach, and Resource Center (Thirdhand Smoke Resource Center) that will connect Thirdhand Smoke researchers with California’s diverse communities. The Thirdhand Smoke Resource Center (1) established a web-based platform to share Thirdhand Smoke information and outcomes from consortium-supported research with California residents, communities, tobacco groups, and business owners (Aim 1); (2) raises awareness among California residents through social media campaign; (3) shares what we know about Thirdhand Smoke with community groups, health professional, and relevant tobacco control stakeholder groups through a series of online workshops; and (4) engages community groups, health professionals, and business owners about adopt policies related to Thirdhand Smoke.

When Dr. Matt is not busy with his research and teaching, you can find him in San Diego’s backcountry trail-running and birding, in the backyard raising heirloom tomatoes and orchids, in the kitchen baking bread, or at an Aztecs basketball game.

Thomas E. Novotny, MD, MPH, DSc (Hon)

Professor Emeritus School of Public Health

More About Dr. Novotny

Dr. Novotny is an Emeritus Professor of Epidemiology and Biostatistics in the Graduate School of Public Health at San Diego State University (SDSU). Previously, he was Professor of Global Health and Co-Director of the Joint PhD Program in Global Health at SDSU and UC San Diego. He was Deputy Assistant Secretary for Health (DHHS) in 2015-17, where he was involved in federal programs on tobacco control and public health. He has been a contributor to and editor of several Reports of the US Surgeon General on Tobacco and Health.

Dr. Novotny’s research has most recently focused on the environmental impact of tobacco use, and he initiated and guided the production of a WHO Overview on the life cycle impacts of tobacco on the environment. He also founded the Cigarette Butt Pollution Project, a 501c3 charity registered in California, which involves several multi-sectoral collaborative partnerships. He has conducted extensive policy research, advocacy, and conceptual work in this area for over a decade. These activities included work with SDSU and UC researchers on the environmental exposures resulting from tobacco product waste. He has conducted successful dissemination activities with the Truth Initiative in Washington, DC, the California Tobacco Control Program, and other tobacco control advocacy groups.

Nathan G. Dodder, PhD

Adjunct Professor of Public Health

More About Dr. Dodder

Dr. Dodder works in the San Diego State University School of Public Health Environmental Health Laboratory. An analytical chemist specializing in applications related to environmental and public health, his expertise includes:

1) Analytical method development for the quantification of contaminants, metabolites, and protein biomarkers by chromatography/mass spectrometry

2) Non-targeted mass spectrometry for the identification of unexpected environmental contaminants

3) Environmental survey design to assess the occurrence and fate of contaminants in abiotic and biotic matrices

4) Implementation of quality assurance/quality control procedures for chemical analyses

5) Scientific software development, including tools for mass spectral interpretation and mass spectral libraries, automated quality control validation, and data analysis and visualization.

Dr. Dodder is a Co-Investigator of a couple of MERG projects. In these projects, he leads method development for qualitative and quantitative chemical analyses, with responsibility for QA/QC, laboratory maintenance, and training and supervision of laboratory technicians and student lab assistants.

Lydia Greiner, DrPH

Adjunct Professor of Psychology

More About Dr. Greiner

Dr. Greiner uses community-based research approaches to examine the relationships between man-made environmental hazards and health outcomes. Dr. Greiner is the Coordinator for the Thirdhand Smoke Resource Center. In this role, she is responsible for the day-to-day operations of the Center. With more than twenty years of experience in community-based health promotion, she collaborates with other members of the Center Team, thirdhand smoke researchers, and community stakeholders in the outreach and dissemination efforts of the Center.

Christopher R. Harrison, PhD

Associate Professor of Chemistry

More About Dr. Harrison

Dr. Harrison’s research centers on the application of chromatographic techniques, principally capillary electrophoresis, for bioanalysis. This ranges from developing coatings and approaches for the separation of proteins and small molecules, to the application of capillary electrophoresis in detecting blood doping agents in athletes.

Dr. Harrison is a co-Investigator of a MERG project measuring and reducing exposure to thirdhand smoke. His role in the project is to develop and test a simple, field-deployable, device capable of performing semi-quantitative analysis of thirdhand smoke residue. The aim is to provide the public with a tool that can be used by anyone (like a pool chlorination test kit) to get an approximation of the amount of thirdhand smoke residue present in their living spaces.

Eunha Hoh, PhD

Professor of Environmental Health

More About Dr. Hoh

Dr. Hoh’s research interests have focused on fate and behaviors of persistent organic contaminants in the environment and their impact on human health. Her current research projects focus on the ocean and human health, exposure to tobacco smoke residue (thirdhand smoke), microplastic pollution, tobacco product waste, and wastewater treatment.

Dr. Hoh is the Co-Principal Investigator (Co-PI) a Co-Investigator of a few tobacco projects funded by the Tobacco-related Disease Research Program, including the Thirdhand Smoke Resource Center. She has developed novel analytical methods which included fast and efficient analyses of multiple classes of targeted chemical residues, and a nontargeted analytical approach for organic contaminants of interest in various types of environmental and biological samples. She leads chemical analyses required for identifying chemicals of concern in thirdhand smoke and evaluating removal of them as well as contributing expertise on analyses of environmental samples and the design and interpretation of all lab analyses.

Melbourne F. Hovell, PhD, MPH

Adjunct Professor of Public Health

More About Dr. Hovell

Dr. Hovell’s research focuses on the etiology of health-related behavior following the Behavioral Ecological Model, including studies of classic risk practices, such as diet and physical activity, as well as studies of clinicians’ service delivery. His research also addresses means by which the influence of and change in culture can be achieved to establish healthy practices in whole populations. His work investigation of secondhand smoke exposure reduction for children led to him, along with Dr. Georg Matt, to “discover” thirdhand smoke when he explored nicotine in homes as an explanation of variance in secondhand smoke exposure.

He is a Co-Investigator of the Thirdhand Smoke Resource Center. In this role he will contribute to the translation of thirdhand smoke research findings to real-world settings to disseminate findings and improve public health.
