His clinical interests and research for the last 25 years have focused on medical conditions characterized by chronic fatigue. His work has focused on the pathophysiology of symptoms associated with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), including the overlaps of orthostatic intolerance, joint hypermobility/Ehlers-Danlos syndrome, and adverse biomechanical strain.

He has directed the Chronic Fatigue Clinic at the Johns Hopkins Children’s Center since 1996, where he is the inaugural recipient of the Sunshine Natural Wellbeing Foundation Chair in Chronic Fatigue and Related Disorders.

The Chronic Fatigue Clinic evaluates adolescents and young adults who have medical conditions characterized by chronic fatigue.

Kevon Jackman, DrPH, MPH

Dr. Jackman is an Instructor of Pediatrics in the Division of Adolescent and Young Adult Medicine who joined our team in 2021 after completing postdoctoral fellowship training in the Drug Dependence Epidemiology Training Program at the Johns Hopkins Bloomberg School of Public Health.

He is an HIV Epidemiologist and Prevention Scientist who has focused his career as an HIV/STI interventionalist focused on designing and implementing health information technology (Health IT) tools that empower youth to engage in their sexual and reproductive health. He has designed and implemented mixed-methods studies to understand perceptions of college-aged youth on using portals for receiving HIV/STI test results and for sharing electronic results with partners (R36 HS023057-01). His early dissertation research is one of the first studies to demonstrate that minoritized youth believe PHRs benefit from improving the occurrence of STI testing communication between partners and the accuracy of screening information shared between partners.

Dr. Jackman also brings multi-disciplinary research team experience. During my postdoctoral training, he served as a quantitative research team member on a study focused on validating metrics for sexual behavior stigma across the United states and sub-Saharan African countries and as a qualitative research team member on a study to understand perceptions of research participant to make it more meaningful to Black MSM in Baltimore.
