Dr Fiona Cresswell

Clinical Assistant Professor

United Kingdom

I am a practicing clinician in HIV and Sexual Health at University Hospital Sussex and an active clinical academic working on improving the treatment of HIV and opportunistic infections in sub-Saharan Africa.

I hope to support the effective and equitable implementation of long-acting HIV treatments in programmatic care settings in Africa through clinical trials, clinical pharmacology, translational and implementation research. I am Lead Investigator of a phase III randomised clinical trial called IMPALA 'Improving HIV outcomes in Africa with Long-acting Antiretroviral therapy' so I work closely with colleagues at the trial coordinating centre at MRC/UVRI-LSHTM Uganda Research Unit and collaborators in Uganda, Kenya and South Africa. I am also site-investigator on the Cabotegravir and Rilpivirine Efficacy and Safety (CARES) study in Uganda.

My PhD research was with the Infectious Disease Institute in Uganda where i worked with the meningitis research team on improving the diagnosis and treatment of TB meningitis. I continue to study TB meningitis an Investigator on the HARVEST multi-country trial of high-dose rifampicin for TB meningitis at the Infectious Diseases Institute, Uganda, Caprisa in South Africa, Oxford University Clinical Research Unit in Indonesia, Universities Padjadjaran, Radboud University in the Netherlands and University of Minnesota.
