More specifically, she is interested in the relationship between race/ethnicity, socioeconomic status, and gender and caregiving in the US context. Her dissertation research focuses on the physiological and mental health of mid-life US women who serve as informal caregivers to elderly adults, possibly while simultaneously caring for dependent children, and the mitigating effects of health services and social support.  Prior to beginning her doctoral studies, she earned a Master of Arts in Sociology at UNC-Chapel Hill in 2020 and Morgan State University in 2011, as well as a Bachelor of Science and Master of Science in Exercise and Sport Sciences from the University of Florida in 2001 and 2003, respectively.

Phillip Hughes, MS (Pharmacy)

Phillip Hughes, MS, is a PhD student in the Division of Pharmaceutical Outcomes and Policy at the UNC Eshelman School of Pharmacy. His research interests center around mental health services and substance use treatment with a focus on improving access to care through policy. In particular, his current research examines how scope-of-practice issues, such as prescriptive authority, impact the availability and quality of treatment services. Secondary lines of research include outcomes of state-level opioid policies and how the prevalence of adverse childhood experiences (a risk factor for mental health and substance use disorders) have changed over time. To date, he has worked on projects covering a breadth of topics, including studies on opioid policies, insurance networks, adverse childhood experiences, and psychotropic polypharmacy. These projects focus on a wide range of populations, such as people with disabilities, lgbtq+ individuals, and children with special healthcare needs. His overarching goal is to improve access to quality, equitable mental health care and substance use treatment services.

Chase Latour (Epidemiology)

Chase Latour is a 4th year doctoral student in the Department of Epidemiology at UNC-Chapel Hill Gillings School of Global Public Health. Her broad goals as a researcher are to provide evidence on medication safety and efficacy among patients typically excluded from clinical trials while investigating methodologic issues that complicate these study questions. Her dissertation is focused on pharmacologic treatment of chronic hypertension in pregnancy and exploring how to better investigate these questions in electronic health record data.


Mustafa Abid, MD (General Surgery)

Mustafa is a 4th year General Surgery resident at UNC.  Following Davidson College for his undergraduate degree, Mustafa attended Wake Forest School of Medicine for his medical degree before coming to UNC for his General Surgery residency.
