Dr. Claud Crosby's interest in global health began long before he entered the field of medicine. He completed his undergraduate degree in Biology at Georgia State University and went on to earn a Master of Public Health with a concentration in Global Health from Emory University. He then completed medical school at Morehouse School of Medicine and OBGYN Residency at Memorial Health University Medical Center in Savannah, Georgia, where he served as Chief Resident.

Dr. Crosby's commitment to global health in Africa spans more than two decades, beginning in 2004. His work across South Africa, the Kingdom of Eswatini, Mozambique, Uganda, the Democratic Republic of Congo, Kenya, and Malawi has addressed a broad range of pressing public health challenges, including HIV, tuberculosis, community health, and orphan care. Since 2013, his focus has shifted to women's health, where he has directed his efforts toward obstetric fistula and cervical cancer prevention, diagnosis, and treatment. He began working at Gynocare Women's and Fistula Hospital in 2016 and has served on its Board of Directors since 2024. To further support this work, Dr. Crosby founded Maryam Health, a non-profit organization established to advance African-led women's health initiatives, including the work of Gynocare across the continent.

Now serving as Clinical Instructor of Obstetrics and Gynecology at Vanderbilt University School of Medicine and as a generalist obstetrician and gynecologist, Dr. Crosby brings this depth of experience to his work at VUMC. His specific global health interests include obstetric fistula prevention and treatment, cervical and breast cancer care, and hospice care for women in low-resource settings.

Dr. AJ Mata’s interest in global health began while obtaining her undergraduate degree in Anthropology and Biology at The Ohio State University. This led her to put her plans for medical school on hold to join the United States Peace Corps, where she served in Antaretra, Madagascar as a Community Health Volunteer. She then transitioned to a position in Madagascar’s capital, Antananarivo, as the Malaria Technical Officer for USAID|Deliver Project through the U.S. Peace Corps Response program. There, she worked on the supply chain management of antimalarial commodities, including a national long-lasting insecticide-treated net (LLIN) distribution campaign.

After 3.5 years in Madagascar, she returned stateside and completed a dual MD/MPH program at the University of Miami, during which she focused her attention on serving communities in south Florida. OBGYN Residency at Vanderbilt University Medical Center (VUMC) brought her the first opportunity to work clinically in Kenya while she completed a 1-month elective at Kijabe Mission Hospital. She then moved abroad again for a fellowship at the University of Toronto. She spent the first year in Toronto, where she provided care for Ontario’s population, with services primarily focused on First Nation, refugee, immigrant, and persons who use substances. Her second year brought her back to Kenya, where she served as the AMPATH (Academic Model Providing Access to Healthcare) Reproductive Health Team Lead at Moi Teaching and Referral Hospital (MTRH). Now that she has returned to VUMC as Global Women’s Health Faculty, she plans to continue partnerships with Kijabe Mission Hospital and MTRH with a focus on medical education and capacity building for minimal access surgery.

Dr. Lindsey Zamora’s interest in global health and cultural studies started before she entered the field of medicine. She completed her undergraduate degree in Anthropology at the University of Florida and during this time, she studied abroad in Tanzania and Brazil.  She then completed medical school at the University of Florida and went on to residency training at the University of Florida and Baylor College of Medicine. During medical school, she led an ongoing mission trip to the Dominican Republic providing care for rural areas of the country. In residency, she had the opportunity to rotate in Zambia working with midwives leading safe delivery training workshops.

After residency, Dr. Zamora completed a fellowship in Global Women’s Health through University Hospitals/Case Medical Center in partnership with University of Guyana and Georgetown Public Hospital Corporation. During this time, she helped establish the first Ob-Gyn training program in the country. The program was developed with the goals of training local specialists and leaders in Ob-Gyn in the country of Guyana to reduce the country’s maternal mortality rate.  Dr. Zamora lived in Guyana for two years during her fellowship and helped to graduate the country’s first specialists in Ob-Gyn. After her fellowship’s completion, she then continued her work from the United States as an Assistant Residency Program Director for the program.  During this time, Dr. Zamora earned her Master of Public Health from the London School of Hygiene and Tropical Medicine. Dr. Zamora’s specific global health interests are maternal mortality reduction, global health education, capacity building in low and middle income countries, and care for immigrant and refugee populations.
