Our Team

Sophia Hussen, MD, MPH

Principal Investigator/Associate Professor

Rollins School of Public Health

Department of Medicine, Division of Infectious Diseases

Sophia is a public health researcher and infectious diseases physician focused on HIV among adolescents and young adults, with a focus on young Black gay and bisexual men.

Marxavian Jones, MPA

Manager of Research Projects

Growing up in MS presented Jones with a clear illustration of the impact of institutionalized racism and poor healthcare accessibility on the health outcomes of black people. He noticed that his community was being negatively impacted by health disparities and inequalities. As a response, he has been an advocate for social justice and the end of discrimination against marginalized populations, such as people of color and the LGBT community, for numerous years. He collaborates with local Community-Based & AIDS Service Organizations to raise community consciousness as it pertains to the impact of the HIV epidemic in the Deep South. Jones aspires to continue aiding the fight against epidemic and poverty, improve capacity-building among key populations, and build young black leaders across the globe.


Kamini Doraivelu, MPH

Public Health Program Associate

Kamini has been a member of the EmPOWER team since she was an MPH student at Rollins. After graduation, she stayed on with the team and now coordinates the CHIMES, VOT+, and iTransition studies. Her favorite thing about the EmPOWER team is that we’re like a family and support each other. When Kamini is not working, you can probably find her snuggling Sconnie (her dog). She’s a proud Wisconsin alumna and never misses a Badger/Packer game day. Kamini plans to attend medical school in the future.


Antonio Newman Jr., MBA

Research Administrative Coordinator

Tony coordinates several studies including VOT+, OpenMind, and MobiliTy. His favorite thing about being a part of our the team is the balance between work and fun. We laugh and uplift one another, but we know how to get the job done. We take ‘work hard, play hard’ to the next level. Even when it is done virtually. Prior to COVID, you could catch Tony bowling or at the movies…he’s a sucker for a good Marvel movie. Now, he plays it safe and binge watches everything on Netflix and HBO Max. Tony plans to further his education and receive a PhD in Clinical Social Work.


Ariana Pather, MPH

Public Health Program Associate

Ariana grew up in South Africa, which has driven her interest in HIV research and health advocacy. After graduating with her MPH from Brown University, she worked at the HIV Center for Clinical and Behavioral Studies in New York. Her research has focused on adolescents and young adults living with HIV in both South Africa and the United States; including their experiences with mental health, adherence to HIV medication and family dynamics. As a new member of the EmPOWER team, Ariana is joining the iTransition, Open Mind, Mobility and CHIMES studies. She loves the team’s collaborative energy and is excited to be joining the EmPOWER family! 


Madeleine Goldstein, DO, MPH

Assistant Professor,

Department of Pediatric Infectious Diseases

Maddie is a pediatric infectious disease physician and public health researcher under the mentorship of Dr. Hussen. Her research aims to mitigate the effects of intersecting stigmas and improve HIV-related outcomes through innovative intervention design and implementation among children and adolescents living with HIV. Atlanta has quickly become a second home and when she is not working, you can find her cooking a new recipe, exploring the botanical gardens, or traveling somewhere new!


Rosalind Byrd

Graduate Research Assistant

MD/MPH Candidate

Growing up with family on the Southside of Chicago and rural Mississippi, Rosalind became acutely aware of the disparities in quality and access to care.  Her interest in public health was incited by an internship in college during which she worked with a community based organization working to reduce incidence of HIV within the Black community. Working with the EmPOWER team has broadened her understanding of how academic research can help community members build capacity and self-efficacy. In her free time, Rosalind enjoys gathering with friends, listening to podcasts, and challenging herself physically on aerial hoop and aerial sling.


Chloe Chaudhury

Graduate Research Assistant

MD/MPH Candidate

Chloe is currently a fourth year medical student at NYU School of Medicine taking a year to do an Masters of Public Health at Emory University.  She worked on a community based study in Northeast D.C. where she sparked interests in the social, emotional, and systemic injustices that intersect with infectious diseases, substance use, and unique needs of LGBTQ+ populations. Chloe hopes to pursue a career in adolescent medicine, as she is passionate about health education, serving her community of LGBTQ+ and Southern folks, and conducting research to improve the lives of historically oppressed populations. She loves to choreograph, practice, and perform all forms of dance, enjoy nature, engage in community activism, and travel. 


Katie Sharma

Research Assistant, Discovery Project

MD Candidate

Katie left her job in healthcare consulting and analytics to pursue a more meaningful career (medicine). Her favorite memories from medical school so far include when she was engaged with the community, like when she volunteered for the local Covid-19 pandemic and Monkeypox outbreak response teams to administer vaccines. Katie will be working on the CHIMES study. When she is not at the hospital, she is with her husband chasing around their three-year-old son, Grady. She is interested in a future career in infectious diseases and HIV primary care.
