Dr. Davis has practiced and taught surgery in Kenya full-time since 2007 at AIC Kijabe Hospital. He helped start the General Surgery residency in 2008. His interests include trauma and acute care surgery, oncologic surgery, head and neck surgery, facial fracture care, and surgical education.
Dr. Castilho is an associate professor and physician-scientist in the Division of Infectious Diseases at Vanderbilt University Medical Center. Dr. Castilho received her MD and MPH from Johns Hopkins University. She completed her residency in internal medicine and fellowship in infectious diseases at Vanderbilt. She joined the faculty in the Division of Infectious Diseases at Vanderbilt in 2015. Shortly after, she received a K23 Career Development award from the National Institute of Allergy and Infectious Diseases (NIAID) to study aging in adults with HIV. Her research on long-term outcomes of adults living with HIV utilizes observational cohorts of adults with HIV, including locally in Nashville, nationally with the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD), and internationally with the Caribbean, Central, and South America network for HIV epidemiology (CCASAnet). She is a PI of an R01 from the National Institute on Aging with a research focus on the non-infectious and long-term outcomes of adults living with HIV in Brazil. She has additional research expertise in infectious diseases and women's health and is the project PI for the HPV Impact study of the TN Emerging Infections Program. Dr. Castilho also sees patients with HIV at the Vanderbilt Comprehensive Care Clinic.
Dr. June Fabian is a clinician scientist specializing in the epidemiology of chronic kidney disease (CKD) in Africa. She is a founding member of the African Research on Kidney Disease (ARK) Consortium, which comprises centres of research excellence in Malawi, South Africa, and Uganda, and maintains strong ties with the London School of Hygiene and Tropical Medicine in the UK. Dr. Fabian trained as an MD and specialized as a physician, followed by a subspecialty in nephrology at the University of the Witwatersrand in South Africa.
Her doctoral research was conducted at the rural SA/MRC Wits Agincourt Health and Demographic Surveillance site in Mpumalanga province, where she determined the population prevalence and associated risk factors for CKD. Additionally, she evaluated the performance of creatinine and cystatin C-based eGFR equations using plasma excretion of iohexol as the reference GFR. This study was the most extensive of its kind conducted in Africa, revealing that creatinine is a poor biomarker for eGFR and that the prevalence of CKD in African populations had been previously underestimated.
Dr. Fabian's findings have significant implications for both individual patient care and public health in Africa. Through the ARK Consortium, she collaborates with colleagues at VIGH to enhance the understanding of genetic risk factors related to CKD incidence and progression in African populations, while also facilitating comparative studies with different population groups in the USA.
