University of Chicago - PhD in Cancer Biology and MS in Translational Science, 2010-2014
Brown University - BA in Biology, 2005-2009
I completed postdoctoral training at The Dartmouth Institute for Health Policy and Clinical Practice and I joined the faculty in the Department of Biomedical Data Science at the Geisel School of Medicine at Dartmouth in 2018. The underlying motivation behind my research program is to evaluate and optimize cancer patient access to care and outcomes by analyzing large health and health care datasets.

On Dr. Moen’s team, I am currently working on a project aimed at understanding cancer care delivery. In this project, I provide programming and analytic support in Medicare claims data to create a cohort of breast cancer patients and physician network datasets. Before coming to TDI, I worked as a Research Scientist at the Carsey School of Public Policy where I used US Census data to investigate rural-urban disparities in various economic, educational, and social outcomes.

Harvard University – BA in History and Science, secondary in Global Health and Health Policy, 2013 – 2017
I’m a PhD student in the QBS program studying health services research and biostatistics in Dr. Moen’s Lab. I’m passionate about researching access to and quality of care at the intersection of cancer and women’s health care, and about applying causal inference methods to study these topics. In Dr. Moen’s Lab, I’ve worked on projects that apply health services research to cancer care delivery, and network analysis methodology to large medical claims datasets. I’m excited to apply the skills that I learn in Dr. Moen’s Lab to help improve access to and quality of cancer care and women’s healthcare. Before Dartmouth, I worked on a healthcare consulting team as a Data Analyst/Consultant where I analyzed and managed health plan utilization and costs.

I am a PhD student in the QBS program, and I joined Dr. Moen’s lab in 2024. I’m interested in researching social determinants of health that impact quality of care and patient experiences. I'm excited to learn how network analysis methods can be utilized to better understand these disparities. Before coming to Dartmouth, I researched applications of random matrix theory for network analysis and worked in a cancer genetics lab.

Mount Holyoke College - BA in Chemistry and Data Science, 2018-2022
I’m a PhD student in the QBS program and joined Dr. Moen’s lab in 2025. I’m interested in cancer care trajectories and patient-sharing patterns. I’ve worked on interdisciplinary projects at the intersection of clinical research and AI, leveraging clinical data such as EHRs, claims and images to support health outcome prediction and advance precision medicine. I’m excited about applying data-driven approaches to address healthcare challenges and improve care delivery.
