DrPH Student Profiles
Nadine Alexander
- 2020
I am a fourth-year DrPH candidate in the Department of Epidemiology. My research interests include reducing health and racial disparities and reducing experiences of oppression during service delivery. My research aims to improve HIV support service delivery and HIV outcomes using community-driven practices to inform programming and policy. For my Integrated Learning Experience, I am interested in assessing the specific ways in which different types of stigma are manifested in HIV service delivery for minoritized people living with HIV. Through this project, I hope to influence changes in programming and policy that will improve the overall HIV service utilization experience and engagement along the different stages of the HIV Care Continuum for recipients of Ryan White Part A services. I currently work at the New York City Department of Health in the Bureau of Hepatitis, HIV, and STIs. I regard health equity as an essential element to helping reduce health and racial disparities of any kind. As a result, in my role, I lead efforts to ensure all aspects of the program’s work follow equitable practices and help ensure consumers of Ryan White Part A services receive services commensurate with their level of need.

Tameir Holder
- 2020
I have been engaged in public health research and practice for over 15 years. My professional background is largely based within the non-profit sector, where I remain engaged in research pertaining to health services, comparative effectiveness, and patient-centered outcomes. Particularly, I have contributed to a range of studies that are designed to support medically underserved communities that traditionally have high rates of chronic conditions such as cardiovascular disease, diabetes, and cancer. This work involves collaborating with federally qualified health centers and safety-net hospitals, in New York and throughout the U.S., to understand barriers to care while examining intervention implementation and effectiveness.
Currently, I am exploring the intersection of care management and health policy. I plan to use mixed-methods approaches to ascertain how federal and state policies, evidence-based care models, and quality improvement initiatives impact health outcomes among patients with complex medical needs. My experience with program evaluation, data analysis, and project management will facilitate this endeavor. I earned a Bachelor of Arts in Psychology from Wesleyan University and completed a Master of Public Health degree in Epidemiology, with a certificate in Chronic Disease, at Columbia University, Mailman School of Public Health.
