Byron spent four years in El Salvador with a non-governmental organization working with thousands of war displaced living in mud huts along a railroad track. During that time he established a clinic, trained health workers, developed a disease surveillance system, and help build a community center that included a library for children. Following that work he continued his education for his PhD at Johns Hopkins in Maryland, acting as a teaching assistant and later teaching a range of courses and guest lecturing. During his time at Hopkins he established workshops to support graduate and medical students in biostatistics and epidemiology and founded the Health and Human Rights Group.  He was a biostatistician for a range of major on-going cohort studies and clinical trials at Hopkins, including HIV/AIDS, addictions, program evaluations, and treatment protocols.  He also worked on many dozens of smaller projects as a biostatistician and analytical epidemiologist. For his PhD he received a grant from NIH to conduct a study of the associations of weight cycling and type II diabetes (both hormonal processes) on postmenopausal breast cancer. Outside of these research and teaching activities on-location at Hopkins, Byron has also supported health service evaluations and taught various courses for Hopkins in Cambodia, Vietnam, Afghanistan and Spain. While in Baltimore he also worked for the State of Maryland in the AIDS Administration as a research statistician and as a TB Epidemiologist for the TB Division of the Maryland State Department of Health & Mental Hygiene.   Following these positions, Byron worked with the WHO office for the region that included Cambodia, Vietnam, and the Philippines.  On completion of that contract, he took a position in the technical unit of the regional headquarters of the World Health Organization (WHO) for the Western Hemisphere, based in Washington, DC.
