Dr Chegou was trained as a Medical Laboratory Scientist at the Faculty of Health Sciences, University of Buea, in Cameroon. After working briefly as a laboratory scientist in hospital laboratories, he then moved to South Africa, where he completed his postgraduate and post-doctoral studies in the field of Tuberculosis Immunology.
Dr Chegou's research work mainly focuses on biomarkers for the Immunological diagnosis of tuberculosis disease, and monitoring of the response to tuberculosis treatment. He is particularly interested in the development of simple field-friendly point-of-care diagnostic tests for the rapid diagnosis of tuberculosis disease as well as monitoring of the response to tuberculosis treatment in resource-constrained settings. Dr Chegou and colleagues are currently developing a new blood based test for the diagnosis of active TB disease using finger-prick blood – in a project that is funded by the EDCTP (Principal Investigator; Prof Gerhard Walzl- www.screen-tb.eu). The group has also been funded to develop a similar biomarker-based point-of-care test for monitoring of the response to TB treatment and prediction of TB treatment outcome.
Dr Chegou has co-authored 48 publications in peer-reviewed international journals, several conference presentations, and is listed as an inventor on seven patent applications on diagnostic biosignatures for tuberculosis disease. He is a frequent peer-reviewer for international journals, funding organisations and is a member of professional organisations. He currently supervises postgraduate students and is a South African National Research Foundation (NRF) rated scientist.
Infectious disease immunology, with particular focus on the immunology of Mycobacterium tuberculosis infection. Dr Chegou is currently working on biomarkers for the diagnosis of tuberculosis diseases, biomarkers of protective immunity against Mycobacterium tuberculosis and biomarkers for monitoring of the response to TB treatment amongst others.
