QBS Mentor: Margaret Karagas, PhD

Thesis title: Epidemiologic characterization of human polyomaviruses in adults from the United States, and their relation to cutaneous squamous cell carcinoma

Working with Dr. Margaret R. Karagas, I investigate the seroepidemiology of human polyomaviruses, and their relation to skin cancer, in a large population-based case-control study. I hope to extend my research into the New Hampshire Birth Cohort, where I'd like to explore the association between infant health and measures of polyomavirus immunity. Having been given the opportunity to address novel hypotheses at the level acceptable for peer-reviewed publications, develop collaborations with other labs worldwide, and attend multiple conferences yearly with additional support from graduate school travel awards, I have greatly enjoyed my time with my research group.

QBS Mentor: Christopher Amos, PhD

Thesis title: Characterization of cancer risk and response to immunotherapy through pathway-based genomic analyses

I am now doing clinical rotations in the final 2 years of the MD/PhD program following graduate study in QBS. I look forward to using my training in cancer genomics and big data as a physician-scientist who tailors precision therapy in one of the oncology specialties: medical oncology, surgical oncology, or radiation oncology. Current rotations will help guide that decision.Publications

Education: New England College - Mathematics

QBS Mentor: Scott Williams, PhD

I chose the QBS program because I was intrigued by the multidisciplinary aspect of the research. This gave me the ability to apply my knowledge of mathematics in a practical setting. I am working on applying network theory to novel genetic associations. I like working with Scott Williams because he encourages me to think independently, yet offers my guidance when I need it. I have come a long way in understanding since I joined his lab.

QBS Mentor: Carmen Marsit, PhD

Thesis title: Genomic and clinical data integration for improved cancer prognostic and predictive models

I'm originally from western Maine and prior to 2010 spent almost 15 years in the health publishing industry. Eventually I went back to school at the University of Southern Maine and during my undergrad, I joined the Congdon lab, where I developed a machine learning approach to inferring cis-regulatory modules of transcription factor binding sites. This research led me to become interested in all pre- and post-transcriptional regulation of genes and to notice that epigenetic data are underutilized by many projects that seek to unravel disease etiology. I joined the QBS program at Dartmouth because of its vision of a new type of researcher that can help connect specialists in different areas: epidemiology, biostatistics, and bioinformatics. Dr. Marsit has built a lab with people of diverse backgrounds to do research that cuts across all of these fields. As part of the Marsit Lab, I am developing new tools that enable integrative analyses of multiple, high-dimensional datasets using machine learning to reveal the connections between environmental exposure, epigenetic control, gene expression, and disease.

QBS Mentor: Jane Hill, PhD

Thesis title: Thesis Title: Metabolic fingerprinting of Gram-negative pathogen groups with a focus on the identification of carbapenemase-producing Enterobacteriaceae

Working with Dr. Jane Hill, my research focused on the identification of metabolic fingerprints capable of identifying carbapenemase-producing Enterobacteriaceae (CRE), a critically-important pathogen group that contributes to substantial morbidity, mortality, and healthcare costs. Potential applications of this approach include the rapid identification of CRE from human specimens such as blood or sputum. Having completed my PhD, I now return to the MD program at the Geisel School of Medicine, with an anticipated graduation in 2020. I intend to use the next year of medical school (M3) to explore different career choices, and am grateful that my training through the QBS program has provided me with a useful set of skills irrespective of what specialty I eventually choose.
