Dr Khethelo Xulu is part of the first cohort of the Tirisano programme Track A scholars who visited UCLA for their research training in 2016. His research interest is centred on discovering molecular markers (epigenetic and genetic variations) associated with stress and trauma exposure, which may be essential for prognosis, diagnosis and therapeutic response predictions. He is a registered Medical Scientist trainee with both the Health Profession Council of South Africa (HPCSA) and the South African Council for Natural Scientist Profession (SACNASP). He is a Clinical Scientist Trainee at National Health Laboratory Service (NHLS)/Groote Schuur Hospital (GSH), Cape Town, South Africa. Khethelo seeks to foster collaborative work with fellow scientists, clinicians and psychologists for better understanding of psychoneuroendocrinology and psychiatric genetics pathways, particularly for African populations and historically underserved communities.
