PhD student, jointly mentored by Brock Christensen and Arminja Kettenbach
Program in Experimental and Molecular Medicine, 2015-present

Understanding the underlying biology of disease is my passion. For this reason, I pursued undergraduate study in Biology at Pacific Lutheran University and graduate study in Biochemistry at the University of Michigan. I gained laboratory research experience in a variety of disciplines, including developmental biology, immunology, neuroscience, and pharmacology. In Summer 2015, I joined the Program in Experimental & Molecular Medicine (PEMM) that aims to advance the mission of translational research at Dartmouth. In Fall 2016, I became a co-mentee of Dr. Brock Christensen and Dr. Arminja Kettenbach, and received the Burroughs-Wellcome Big Data in Life Sciences Training Grant. My PhD thesis aims to integrate epigenetics and proteomics data for a better predication of breast cancer risks, using bioinformatics, biostatistics, and laboratory-bench approaches. Outside of lab, I enjoy baking, gardening, music, and literature.


Despina Karalis
Masters Student

I was born in Athens, Greece, moved to Palm Desert, CA, USA, eventually found myself at Hanover as an undergrad at Dartmouth College studying Biology and Women, Gender, and Sexuality studies.Now I am staying at Dartmouth as a grad student in QBS in Epidemiology. My passions include women's health, reproductive health, sexual health, and the intersections/overlaps of all. I am particularly interested in empowering and helping immigrant and underserved women and researching how the adverse conditions they face affect their and their children's development and health. I am hoping to eventually attend medical school and pursue Obstetrics and Gynecology while also doing research on these topics. On my free time I love cooking, taking long walks, reading, and spending quality time with my friends.


Jai Woo Lee, MS
PhD student, jointly mentored by Margaret Karagas and Jiang Gui

I am originally from South Korea, and I usually enjoy hiking, traveling or writing. I completed my undergraduate studies at Carnegie Mellon University and majored in computer science and mathematics. Before entering graduate programs at Dartmouth College, I mainly focused on graph theory and its application with/to computational methods in Operations Research in the field of Theoretical Computer Science and Discrete Mathematics. I also completed my Master's degree in computer science from Dartmouth College. My current research interests lie in utilizing and developing statistical and computational methods in Bioinformatics, Biostatistics, or Machine Learning to analyze biomedical data related to various fields of Epidemiology. Given the high-dimensional metallomics or metabolomics data in which many entities interact with each other in a complex manner, I am interested in studying graphical models and network analysis techniques for discovering environment-environment or metabolome-environment interactions which may define a complex disease.

I did a rotation in the Cancer Epidemiology Laboratory during the summer of 2015, and eagerly decided to stay on for my thesis work. I am currently working on a genetic association study for lung cancer susceptibility, and am interested in continuing to do research pertaining to the genetic and environmental risk factors for lung cancer. My major interests lie within the realm of disease prevention and translational research. I am co-mentored by Dr. Tracy Onega.


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.


Alexander Titus, BS, BA
PhD student - Christensen Lab
My typical week: study, research, get stuck, get unstuck, implement, get lost in the woods, get unlost out of the woods (repeat).

I'm a PhD student in the Quantitative Biomedical Sciences (QBS) program, where my interests intersect bioinformatics, biostatistics, and epidemiology. When I'm not in lab or class, I'm exploring NE by foot, pedal, or paddle. I'm interested in developing data integration tools and techniques to make analysis of the big data explosion in healthcare easier and more efficient.
I have two bachelor's degrees in Biology & Biochemistry, as well as a minor in Mathematics. Between undergrad and grad school I did research, worked at a start-up and a data visualization company, and then rode my bicycle from Northern Alaska to San Francisco, CA.


Owen Wilkins, BS

Thuy-Vy Nguyen '19
Research-grade eye-trackers are extremely expensive, so low-cost devices that give comparable data quality could allow for much more research to be done. I am researching low-cost eye-trackers and helping test an inexpensive device we have in the lab to determine data quality and how to overcome some known limitations of low-cost eye-trackers. We hope to eventually design cognitive studies with children using these low-cost eye-trackers.

Gabrielle O'Donoghue '17
Gabrielle is a New York native fulfilling her Bachelor of Arts in Sociology, concentrated in health care systems and global health at Dartmouth College. Gabrielle plans to attend graduate school for a dual Masters of Public Health and Masters of Business Administration then hopefully on to her medical degree. She hopes to one day be Chief Executive Officer of a hospital and eventually go into hospital administration and policy reform. When asked how her position with the New Hampshire Health Study has influenced her Dartmouth experience and future career goals, Gabrielle responded: “Working with Joan and the rest of the New Hampshire Health Study staff has taught me enumerable valuable lessons including time management, organization, and confidence in a workplace environment. By having this job, I had the confidence to apply to various internships for my off-term and ended up at a clinical research group that also established a trauma center in the region they were located. Having that work experience in conjunction with my time at the New Hampshire Health Study, has positively molded my desired career path aspirations.” Gabrielle, having worked with the New Hampshire Health Study for over a year now, hopes to continue to grow from her experience here and help with such a an impactful study for the New Hampshire population.
