Junyu Chen

PhD Student (Epidemiology) 

I am a first-year doctoral student in the Department of Epidemiology. Before entering the program, I received a BS in Biological Science (focused on Molecular Biology) from Nanjing University in 2016 and my MPH in Epidemiology (focused on genetic epidemiology) from Emory University in 2018. I also worked in The Center for Computational and Quantitative Genetics in Emory University, where I turned my attention towards a methodological component of gene mapping studies. My current research interest is development and application of novel statistical and epidemiologic methods for multi-omics and GxE studies to understand the genetic contributions to complex diseases and traits. Currently, I am working with Dr. Huels to develop an analysis pipeline for the calculation of DNA methylation risk scores (MRS) and evaluate its robustness and applicability across diverse ancestries through simulation studies and real data analysis. In my free time, I like rock climbing, swimming, hiking and watching stand-up comedies.

Grace Christensen

PhD Student (Epidemiology) 

RESEARCH INTERESTS

I am a doctoral student in the Department of Epidemiology at Emory University’s Rollins School of Public Health. I received my BS in Biology and Evolutionary Anthropology, and my MPH in Environmental Health Sciences from the University of Michigan in 2015 and 2017, respectively. Before entering Emory’s PhD program, I was a CDC/CSTE Applied Epidemiology Fellow working at the Wisconsin Department of Health Services. There, I worked under the Environmental Epidemiology and Surveillance Section on projects ranging from biomonitoring to the development of groundwater standards. Broadly, my interests are in environmental epidemiology, specifically chemical mixtures and their effects on reproductive and developmental outcomes. Currently, I am working in Dr. Huels’ lab on a project analyzing air pollution mixtures and their effect on cognitive function in the Emory Healthy Aging Study.

Zhenjiang Li

PhD Student (Environmental Health Sciences) 

I am currently a doctoral student in the Gangarosa Department of Environmental Health and received a BS in Preventive Health and an MS in Public Health. I have a broad interest in environmental epidemiology, with specific training in omics data analysis and the health effect of traffic-related air pollution on susceptible pollutions, such as pregnant women. My current research focuses on examining the use of saliva metabolomics to measure complex biological responses due to exposure to ambient air pollution. Prior to my PhD program, I worked on interrogating the adverse effects of maternal exposure to second-hand smoke and heavy metals on the development of neural tube defects in offspring in Northern China. I am working in Dr. Huels’ lab on Air pollution and Cognitive Function in the Emory Healthy Aging Study to assess exposures to air pollutant mixtures and estimate the associations between air pollution and cognitive decline among people over 50 years old.
