Tess Leuthner (Joel Meyer, Ph.D. – Fourth Year)
Tess received her B.S. in Environmental Science from Indiana University, where she studied mechanisms and trade-offs of adaptation to phosphorus and heavy metal pollution in Daphnia populations. She then conducted research at the UW Milwaukee School of Public Health for two years, studying the effects of developmental exposures to polycyclic aromatic hydrocarbons and dioxins on nervous and immune system development. Currently, Tess is a third year in the Meyer lab, investigating persistent metabolic effects of developmental exposures to mitochondrial toxicants. Her interests include investigating inter-individual variability in stress response, and how genomic variation (specifically mitochondrial DNA sequence variation) may influence response to stressors at a population level. She plans to develop C. elegans as better prospective ecotoxicological model organism. Contact: email@example.com

Casey received her B.S. in Marine Science with a concentration in Chemical Oceanography from the University of South Carolina in 2014. Currently, she is a fourth year in the Di Giulio Lab. Her research interests involve Atlantic killifish populations that have adapted to withstand contamination from anthropogenic sources and the effect that resistance has on overall organismal fitness in response to other stressors. More specifically, she studies how co-exposures of polycyclic aromatic hydrocarbons and hypoxia impact killifish and zebrafish during embryonic development and how resistance to one stressor or chemical contaminant can influence an organism’s response to another stressor.

Kirsten Overdahl (Lee Ferguson, Ph.D., Heather Stapleton, Ph.D. – Third Year)
Kirsten graduated from St. Olaf College in Northfield, MN, with a B.A. in Chemistry (2015) and a B.M. in Vocal Performance (2016); during the summer of 2015, she traveled to Scotland to work in Dr. Lee Cronin’s Complex Chemical Systems lab at the University of Glasgow. Kirsten is now in her second year at Duke and, after an inspiring rotations experience during her first year, is excited to be part of the Ferguson and Stapleton labs. She hopes to use her time at Duke to consider how best to create iterative workflows for predicting what might happen when humans are exposed to chemicals in the environment; she plans to explore best practices to move between non-targeted contaminant analysis, biotoxicity monitoring, and cheminformatic modeling to determine previously-unrecognized contaminants and their implications for eliciting hormone or immune responses. Ultimately, she hopes to find efficient ways to use comprehensive data to create proactive, preventative measures and policies.
Allison (Alli) Phillips (Heather Stapleton, Ph.D. – Fifth Year):
A native of many western states, Alli moved to Durham from Boulder, CO, in 2014.

She graduated from the University of Puget Sound in Tacoma, WA, in 2012 with a B.S. in Biochemistry. As a graduate student, Alli has been involved in the collection and analysis of samples from indoor home environments to determine children’s exposure to industrial chemicals. Her thesis is focused primarily on isopropylated triarylphosphate esters (ITPs), one of 5 chemicals that have been prioritized for risk assessment by the U.S. EPA.

RECENT ALUMNI (May 2018)
Jessica’s dissertation research focuses on the biogeochemical cycling and impacts of coal ash waste streams in freshwater lakes and selenium toxicity in the context of fish bioenergetic processes. In her work, she considers ecological influences on element distribution between abiotic and biotic environmental compartments, the use of strontium isotopes and element ratios to trace coal combustion residuals (CCRs) through aquatic food webs, and how to pair field assessments with lab-based experiments for effective study of environmentally relevant problems. Her training bridges the fields of environmental toxicology, ecology, public health, and science policy.
Prior to Duke, Jessica obtained undergraduate and master’s degrees from The Johns Hopkins University and spent a year abroad on a Fulbright research grant to Italy.
Xiaoxing Cui Qi (Jim Zhang, Ph.D.):
For Xiaoxing’s dissertation research, she designs epidemiological studies, implements interdisciplinary research projects and performs statistical analysis in examining the cardiopulmonary health impact of air pollution and exposure reduction with exploratory investigations on the toxicological mechanisms.
She is leading a randomized crossover trial among asthmatic children (N=43) to investigate the potential health benefits of indoor air filtration intervention in areas with high ambient air pollution (funded by Underwriter Laboratory Inc). Previously, Xiaoxing led the implementation and statistical analysis of a crossover study on the cardiopulmonary impact of overnight air filtration among healthy adults (NCT02736487). For both studies, her responsibilities included: formulating the study design, identifying the time points and biomarkers for health outcome evaluation, designing subject inclusion/ exclusion criteria and related questionnaires, composing IRB application, studying registration at ClinicalTrial.gov, recruiting and managing research staff and study subjects, budgeting, assessing cardiovascular outcomes and respiratory inflammation during clinical visits, overseeing the collection, unique numbering, storage and biochemical analysis of biological specimens (urine, saliva, nasal fluid, blood) and budgeting. Currently, Xiaoxing is conducting mixed-effects models using R to examine the cardiorespiratory impact of indoor filtration intervention and personal exposure to airborne pollutants.
Previous to PhD training at Duke, she obtained a Master of Science in Public Health degree from Johns Hopkins University, and completed a five-year Bachelor of Medicine program at Peking University.
Jordan Kozal (Richard Di Giulio, Ph.D.)
Jordan holds a Bachelor of Science in Biology from Stanford University (2013). The overarching aim of her dissertation is to characterize the role of mitochondria in the maternal and transgenerational toxicity of polycyclic aromatic hydrocarbons, with applications in both human disease etiology and organismal ecological fitness. She is particularly interested in the potential for transgenerational exposures to reduce an organism’s fitness in multiple stressor scenarios, which are becoming increasingly ubiquitous in the environment due to anthropogenic activities.
