Segun is a public health physician and Epidemiologist. Alongside clinical practice, he worked as a Cochrane author and researcher with Cochrane Nigeria and the Calabar Institute of Tropical Diseases Research and Prevention, Nigeria. There he developed interest in clinical trials and evidence synthesis. He worked on a Cochrane review on the role of vitamin A in preventing blindness in children with measles infection and co-investigated the efficacy of a number of anitimalarial drugs. He has been involved in the conduct of Cochrane systematic review training workshops for more than several years and has conducted and supervised large scale population surveys in Nigeria.

After specialist training at the University of Calabar Teaching Hospital and University College Hospital, Ibadan Nigeria, Segun worked for four years as a researcher at the Nordic Cochrane Centre, Copenhagen Denmark during which time he also obtained a Ph.D in Public Health and Epidemiology at the University of Copenhagen. He worked on bias in randomised controlled trials and prepreclinical studies. He studied the effect of non-use of blinded outcome assessors on treatment estimates in animal model experiments, how authors addressed loss of blinding in trials and also showed that matching as a blinding technique in trials may often be defective.

He also has interests in evidence-based guideline development. He has worked on a World Health Organisation’s evidence synthesis team for the development of the guidelines on the management of health complications from female genital mutilation. He has also been involved in the training of several clinical guideline development committees of professional bodies in Nigeria.
