Julia Anglen Bauer, PhD
Postdoctoral Fellow- Department of Epidemiology
PhD, Boston University School of Public Health, Environmental Health, 2020
MS, University of Illinois at Chicago, Environmental and Occupational Epidemiology 2015
BS and BA, Colorado State University, Biomedical Sciences and Languages, Literatures and Cultures

Dr. Julia Bauer’s research focuses on exposure to environmental chemicals and their impact on the nervous system in children and adults. Before her doctoral training, Dr. Bauer worked as a research scientist for the American Dental Association’s Science Research Institute where she assessed a variety of occupational exposures and investigated associations of occupational mercury exposure and neurological disease in dentists. During her doctoral training, Dr. Bauer was the PI of an NIEHS National Research Service Award (NRSA) to study novel techniques for assessing manganese exposure and children's neurodevelopment, in international (Italy) and local Massachusetts populations. Novel techniques included animal-human translation neurobehavioral tasks, baby teeth as bioindicators of metal exposures and biostatistical mixtures methods. In her postdoctoral work, she is extending her research to develop novel approaches to statistically model neurobehavioral outcomes and to investigate associations between 1) metals measured in baby teeth, water, and neurodevelopmental outcomes, 2) organic chemicals measured in silicone wristbands and birth anthropometry outcomes, and 3) infant diet and metal biomarkers; all within the New Hampshire Birth Cohort Study.

Hannah Laue, ScD, SM
Postdoctoral Fellow - Department of Epidemiology
ScD, Harvard T.H. Chan School of Public Health, Environmental Health, 2019
SM, Harvard T.H. Chan School of Public Health, Environmental Health, 2015
BA, American University, Environmental Studies, 2012

Dr. Hannah Laue's primary research interest is how environmental chemicals affect the neonatal/pediatric gut microbiome and subsequent health impacts, particularly impaired neurodevelopment. During her doctoral degree, Dr. Laue assisted in developing a successful NIH grant to examine the effects of flame retardants on cognitive development, with the microbiome as a hypothesized mechanism. Using preliminary data from this grant she explored the association of polybrominated diphenyl ethers and polychlorinated biphenyls with the gut microbiome. Dr. Laue also employed novel statistical techniques to model the association between environmental metal mixtures and childhood neurodevelopment. In her postdoctoral work, she is building on these past projects to explore how exposure mixtures interact to alter the infant gut microbiome, and how the microbiome can in turn affect social and cognitive development in the New Hampshire Birth Cohort Study.

Catherine C. Pollack, BS
PhD Candidate, jointly mentored by Diane Gilbert-Diamond and Tracy Onega

I am currently a doctoral candidate in the Quantitative Biomedical Sciences program here at Dartmouth. I completed my undergraduate degree with high distinction from the University of Virginia (UVA), where I pursued a double major in biomedical engineering and applied statistics. While at UVA, I participated in two summer internships with the National Academies of Sciences, Engineering, and Medicine (NASEM). At NASEM, I worked with the Board on Mathematical Sciences and Analytics and the Committee on Applied and Theoretical Statistics to develop white papers that bridged the gap between mathematics, statistics, data science and public policy. This experience fueled my passion for science communication; as a result, my dissertation project merges epidemiology and data science to develop software tools that can combat digital public health misinformation. Beyond my formal research, I perform statistical analysis on diverse clinical projects as a consultant with the Biostatistics Consultation Core, serve as a graduate peer writing tutor with the Center for Research, Writing, and Information Technology, and play clarinet with the Dartmouth College Wind Ensemble. I also enjoy running, and I hope to participate in the upcoming Walt Disney World marathon!

Curtis Petersen, MPH
PhD student, jointly mentored by Brock Christensen and Ethan Berke

After a lot of experience working in molecular research I decided to try and understand how macro factors influenced the micro systems I had been studying and working with. In this endeavor I studied epidemiology as a masters student at The Dartmouth Institute where I focused on breast cancer. In 2014 I helped start a remote medical sensing group working on how we can use technology and big data to help people manage their health. This process spurred me into thinking about how we might be able to use this information to interpret epigenetic changes.

I am interested in examining next generation phenotyping, bridging the gap between the exposome and disease. I aim to link the huge amount of data that we are now continuously collecting from people to how it influences genetic expression. I think that our health systems can be greatly improved through advanced analytics of new data. I hope that this work will help influence how policy is shaped and how we measure quality healthcare.
