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 Menstrual Health and Global Women’s Health.

Her work in Menstrual Health includes the establishment of an international research network exploring Menstrual Health, human rights and environmental sustainability in Uganda, Sudan and Kenya and the UK. She supports conversation and learning on the topic of menstrual health across Schools at the University of Sussex, and publicly, giving talks and holding workshops. Her current work explores how to represent young menstruators' needs through citizen science. She is part of the Period Dignity Project at Sussex, supporting access to menstrual products and developing the approach to menstrual health policy.


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 at BSMS 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.
