Judith T. Zelikoff, Past President

IRSS Officer

Dr. Judith T. Zelikoff is Professor in the Department of Environmental Medicine, New York University Langone Medical Center. She received her PhD from Rutgers School of Biomedical and Health Sciences. The major focus of Dr. Zelikoff’s research laboratory has long been the effects of inhaled toxicants on immune system function and the reproductive process. Ongoing studies include those using inhaled nanoparticles, particulate matter (PM), cigarette smoke or its components, as well as alternative tobacco products such as gutkha and hookah. One of her main interests is studying the effects of inhaled metal nanoparticles (oxides of cadmium or silver and gold) on embryonic, fetal, and postnatal development and growth. For instance, her work has shown exposure to inhaled cadmium oxide nanoparticles during pregnancy lead to shortened body length of newborns and leads to diminished rate of weight gain early in life and mechanisms for these actions are part of on-going studies in. Another focus of Dr. Zelikoff’s laboratory is how particulate matter in air pollution causes premature birth and low birth weight. She is trying to understand how exposure at different times during pregnancy can lead to premature birth/low birth weight as well as to determine the mechanisms involved and potential intervention strategies to improve the health of the baby. She has shown experimentally that exposure to PM can cause changes in the uterine environment that lead to premature birth and that timing and duration of exposure are both important factors. A long-time focus of Dr. Zelikoff’s laboratory is gaining a better understand for how cigarette smoking during pregnancy affects the unborn offspring, and how these effects increase a child’s susceptibility to diseases such as cancer or heart disease later in life (i.e., developmental basis of adult disease). Her laboratory has extended this work to examining how smokeless or “heat-not-burn” tobacco products can affect the reproductive process. These products, gutkha (South Asian product) and shisha smoked in a hookah (Middle Eastern product), are traditionally used by ethnic/immigrant populations, but are now being used with greater frequency by the population at large. These products, along with e-cigarettes are being studied for their toxic effects on male and female reproduction, immunity, and brain neurotransmitters which lead to addiction. Dr. Zelikoff has over 150 publications.


Natalie M. Johnson, Councilor

IRSS Officer

Dr. Johnson is currently an Associate Professor in the Department of Environmental & Occupational Health at Texas A&M University. Her research group is currently investigating the effects of air pollution on infant immune and respiratory dysfunction, including oxidative stress and stress-activated signaling pathways as targets for protection. In vivo findings reveal a window of pulmonary immunosuppression in offspring following prenatal PM exposure, and this model served as the basis for characterizing mechanisms underlying PM-driven immune modulation and neonatal respiratory infection risk. Dr. Johnson obtained her Ph.D. in Toxicology, with an emphasis on exposure biomarkers and translational toxicology, from Texas A&M University in 2010. She then completed a post-doctoral fellowship at Johns Hopkins University, focusing on molecular toxicology and mechanisms of chemoprevention. Dr. Johnson has been an active member of SOT since 2006 and served in multiple leadership positions, including peer or host mentor in the Undergraduate Education Program, councilor for the OPHSS (2015&dash2017), councilor/secretary for LSSOT (2019–2020), where she is currently serving as vice-president (beginning in 2021).

Emma Karey, Postdoctoral Representative

IRSS Officer

Emma Karey obtained her doctorate in Pharmacology and Toxicology from the University of California at Davis in 2018, where she characterized the autonomic mechanisms underlying cardiovascular dysfunction induced by environmental tobacco smoke. Upon graduating, she joined the Department of Environmental Medicine at NYU Langone as a postdoctoral researcher working with Drs. Terry Gordon and Michael Weitzman to evaluate the health effects of alternative tobacco products (ATPs), including electronic cigarettes and hookah water pipes. Over the past three years, Dr. Karey has identified novel respiratory effects — ones associated with ATPs that have not been observed with more traditional combustible-tobacco products. She also spearheaded a study that found unique behaviors among ATP users that might explain these differences in respiratory toxicity. This past year, Dr. Karey coauthored several additional publications, including a comprehensive review of e-cigarette toxicity and multiple epidemiological papers identifying novel associations between vaping, inflammation, and mental health. Most recently, she has found respiratory inflammation in children passively exposed to vaping emissions in the home, providing some of the first data to suggest that secondhand e-cigarette exposures may cause harm.
