(Kenneth Korach, MD; Donald McDonnell, PhD):

Laurel received her B.S. in Biology and M.S. in Biotechnology from the University of South Carolina. She is both a Ph.D. Candidate and IRTA Fellow. Defing the Molecular Pharmacology of Antagonist-Mediated ERα Activation: The term Selective Estrogen Receptor Modulators (SERMs) has been used of late to describe a group of pharmaceuticals that manifest estrogen receptor (ER) agonist activity in some tissues, but that oppose estrogen action in others. Thus, it may be possible to capitalize on the tissue-selective pharmacology of these drugs and develop them as treatments for estrogenopathies where it is desirable to direct therapy to a specific estrogen-responsive target organ. It has become clear in recent years that the different pharmacological activities of ERα antagonists, agonists and SERMs are determined by their impact on the overall surface topography of the receptor and the effect this has on the recruitment of functionally distinct coregulators. This realization has provided the impetus for research to define the specific ERα-coregulator interactions involved in the tissue-selective antagonist-mediated ERα activation and to exploit these findings to develop compounds with improved therapeutic utility. Contact:



Xiaoxing (Shallsing) Cui (Jim Zhang, PhD – Third Year):

My research focuses on the exposure assessment of air pollution and its health impact on human health at population level, with exploratory investigations on the mechanism of the toxicological process as well as effective interventions for exposure reduction. Through exposure assessment at the population level, I aim to identify the parameters of exposure that is most relevant to the downstream health effects using data from airborne pollutants, including particulate matter, ozone, nitric oxides, SO2 and CO. Of the adverse health effects, I am interested in disruption of respiratory and cardiovascular function via induction of oxidative stress, particularly among susceptible populations such as children and individuals with pre-existing diseases. Through designing and implementing epidemiological studies on indoor air filtration in urban areas of developing countries, I hope to investigate the effectiveness of interventions available for reducing air pollution exposure as well as discover novel biomarkers that provide a more accurate characterization of personal exposure and early health effects.

Master of Science in Public Health, Occupational and Environmental Hygiene, Johns Hopkins University (Baltimore, MD), 2011 – 2013

Bachelor of Medicine, Preventive Medicine, Peking University (Beijing, China), 2006 – 2011



imagesDrew Day (Jim Zhang, PhD – Fourth Year):

Third Year Graduate Student with Dr. Junfeng Zhang. My research involves using rodent and human studies to evaluate practical interventions, including antioxidant therapies and filtration technologies, to the inflammatory and oxidative effects of urban air pollution exposure. I examine the efficacy of these interventions using blood, breath, and urinary preclinical markers in human trials, as well as similar markers, histology, and epigenetic analysis in rodent models. My hope is to identify an intervention that the average person living in an urban environment can use to reduce their risk of cardiopulmonary disease, allergies, and other diseases related to chronic inflammation. I received a B.A. in Asian Studies, a B.A. in Comparative Literature, and a B.S. in International Studies with minors in Biology and Chinese Language from the Schreyer Honors College at the Pennsylvania State University, graduating with joint honors in Forestry and Asian Studies. I spent a total of 15 months working in Beijing and Shanghai in environmental consulting prior to coming to Duke, gaining a professional proficiency in Mandarin Chinese. My research is largely conducted in China in urban areas with high air pollution. Contact:

Rashmi Joglekar (Joel Meyer, PhD; Susan Murphy, PhD – Second Year):
Rashmi graduated from Indiana University in 2013 with a B.S. in Biotechnology. Her passion for molecular biology and the environment brought her to the ITEHP at Duke University where she is currently working in the laboratories of Dr. Meyer and Dr. Murphy investigating mitochondrial influence on epigenetics. Specifically, Rashmi is using human neural stem cells as a tool to understand epigenetic mechanisms that occur as a response to neurodevelopmental exposure. She hopes to someday be actively involved in policy and environmental justice.





Jordan Kozal (Richard Di Giulio, Ph.D – Third Year):

Jordan holds a Bachelor of Science in Biology from Stanford University. She is interested in mechanistic ecotoxicology— particularly aryl hydrocarbon receptor independent mechanisms of polycyclic aromatic hydrocarbon (PAH) mediated cardiotoxicity as well as their potential to act as selection pressures that underlie the mechanism for PAH resistance in adapted Elizabeth River Fundulus heteroclitus. She is also interested in the effects of remediation on the toxicity of PAHs in F. heteroclitus from contaminated sites.

Before coming to Duke I spent a year working at the Hudson River Superfund Site, where I helped monitor PCB levels in areas of the river before and after dredging. I am now a fourth year doctoral student in Joel Meyer’s lab, and am interested in how deficiencies in mitochondrial DNA content and other mitochondrial processes (fission, fusion and mitophagy) can sensitize an individual to toxicity following mitotoxicant exposure.





Anthony Oliveri (Edward Levin, PhD – Fifth Year):

Anthony is fifth-year student in the Levin Lab, where he wrangles zebrafish in order to examine the ways in which developmental exposures to environmental toxicants, pharmaceuticals, and drugs of abuse produce behavioral and cognitive effects across the lifespan. His thesis specifically characterizes the behavioral toxicology of organophosphate (OP) flame retardants and how it compares to that of OP pesticides like chlorpyrifos. He also helps out with the Neural and Behavioral Toxicity Assessment Core for Duke’s Superfund Research Center, where he advises other researchers in their own investigations into fish behavior. He is a graduate of Grinnell College, where he studied biology, neuroscience, and the inexorable and suffocating emptiness of rural Iowa.
