Research Faculty

Louise Henderson, PhD
Principal Investigator, Director

After graduating from the UNC School of Public Health with a doctorate in Epidemiology, Dr. Henderson joined faculty in the Department of Radiology at UNC Chapel Hill as Assistant Professor in July 2009. Dr. Henderson currently serves as Director of CMR and participates in the Breast Cancer Surveillance Consortium.

Dr. Henderson has over 10 years of experience collaborating with physicians, research scientists, and statisticians in the areas of health services research, quality improvement activities, disease surveillance, and clinical trials. Dr. Henderson’s research interests focus on cancer screening and the application of linked cancer outcomes and Medicare/administrative data to assess patterns and outcomes of care. Dr. Henderson’s interests lie primarily in breast cancer screening and the performance of imaging technologies, comparative effectiveness research, and disparities in cancer screening and treatment.

Sarah Nyante, PhD

Dr. Nyante joined the Department of Radiology in 2014 after receiving her masters and doctoral degrees in Epidemiology from UNC-Chapel Hill and completing a postdoctoral fellowship at the National Cancer Institute.

Dr. Nyante’s main research interests include cancer heterogeneity, the role of hormonal factors in breast cancer risk and prognosis, and mammographic density. Past studies include analyses of change in mammographic density as a predictor of breast cancer prognosis among tamoxifen-treated patients; common genetic variation in adipokine and estrogen-related candidate genes and risk of breast cancer molecular subtypes; smoking and breast cancer risk; and risk factors for rare breast cancer histologic types.


Thad Benefield, MS

Thad Benefield received his MS in Biostatistics from UNC Chapel Hill in 2000. In March 2012, Mr. Benefield joined CMR as a statistician. Mr. Benefield’s primary duties include statistical modeling and creation of analytic datasets.

Katie Marsh, MPH
CMR Project Manager

Katie Marsh joined CMR in September 2013. As project manager, Mrs. Marsh oversees daily operations of Dr. Henderson’s group and works closely with her on a range of tasks including IRBs, grant submissions, budgets, research goals, and staff assignment.

Mrs. Marsh received her BS in Biochemistry from the University of Virginia in 2009 and completed her MPH in Epidemiology at the University of Kentucky College of Public Health in 2013.

Emily Ozdowski, PhD
Research Specialist

Emily Ozdowski joined the CMR in 2016.  She earned both a B.A. and Ph.D. in Biology from the University of Virginia, where she focused on the genetics and development of model organisms.  As a Postdoctoral Scholar and Research Scientist at Duke University, she worked primarily on models of neurodegeneration and the molecular components involved.

At the CMR, ­Dr. Ozdowski supports the research of Dr. Nyante through data analysis, manuscript preparation, grant applications, and IRB submissions.  She is interested in cancer precursors and the mechanisms of transformation to invasive disease, as well as gaining a new perspective on epidemiology and translational medicine.

Michael Pritchard, BA
Data Manager

Michael Pritchard began working with the CMR in November 2016. As the Data Manager, Mr. Pritchard is responsible for coordinating data acquisition from facilities working with the CMR, in addition to managing, preparing, and merging the data-sets for further analysis.

Mr. Pritchard received his BA in Psychology from UNC in 2012 and worked as a Research Assistant at the Center for Developmental Science for several years.
