Dr. James Berkley is the Founder and co-Director of the Childhood Acute Illness & Nutrition (CHAIN) Network of partners in Africa (Kenya, Uganda, Malawi, Burkina Faso), South Asia (Pakistan, Bangladesh), UK, USA, Canada and The Netherlands. The CHAIN Network is headquartered in Nairobi, Kenya, and aims to better understand infectious, immune, metabolic, nutritional, health systems and social pathways to childhood mortality to identify actionable interventions through an epidemiological cohort, systems biology analysis pipeline, social science platform and a multicentre clinical trials platform.

The focus of Dr. Berkley's clinical research is serious infection and survival in vulnerable groups of young infants and children, teaching, training and mentorship. His research group addresses aetiology, clinical features and risks for mortality of serious infections in infants and children; mechanistic studies including microbiology, antimicrobial resistance, immunology, metabolomics and proteomics; and clinical trials, including early pharmacokinetics and safety trials, and large international multicentre phase III trials on antimicrobial and nutritional interventions in vulnerable paediatric populations.
