Biography

Dr Chi Eziefula is a Senior Lecturer in Infection at Brighton & Sussex Medical School and an Honorary Consultant in Infectious Diseases and Microbiology at Brighton and Sussex University Hospitals NHS Trust. She is co-director of CORTH, Centre for Cultures of Reproduction, Technologies.

Chi combines hands on clinical care in infection, tropical medicine and medical microbiology with global health research. Completing undergraduate medical training at the University of Cambridge and University College London she rotated through St Thomas’ Hospital, University College London Hospitals (Hospital for Tropical Diseases) and University Hospitals Sussex for specialist training. She was pleased to join University Hospitals Sussex NHS Foundation Trust as their first infectious diseases registrar, helping set up the service and network within the teaching hospital. Her global health expertise has been supported by Wellcome Trust-funded research positions in Kenya, (Kilifi, KEMRI/ Wellcome Trust Research Programme), and Uganda (Bloomsbury Wellcome Trust Clinical PhD Programme in International Health).

Research

Chi has worked in the field of malaria research since 2005. Her doctoral work at the London School of Hygiene and Tropical Medicine evaluated a pharmacological intervention to block transmission of falciparum malaria in Uganda, conducting the first dose-finding trial for primaquine as a gametocytocidal agent, which contributed to a change in the World Health Organisation malaria treatment guidelines. Her wider research interests include migrant health and global women’s health.

Teaching

Chi teaches infectious diseases, microbiology and clinical and tropical medicine to undergraduates and post-graduate doctors. She leads the Infection and Immunity theme for first year medical students. She teaches on the Scientific Basis of Infectious Diseases module and gives bedside and small group clinical teaching and laboratory-based clinical microbiology teaching to fourth year students. She has taught, examined and been an exam board member on the Diploma in Tropical Medicine and Hygiene at the London School of Hygiene and Tropical Medicine.
