Dr Ann Rawkins

Research interests

My current role is a Scientific Leader providing scientific direction to the TB research programme at HPA Porton. The broad aim of the group is to study the physiology, molecular genetics and pathogenesis of M. tuberculosis in order to identify and further develop vaccine and/or therapeutic targets and to contribute to the development of strategies to control TB in humans by evaluation of vaccines and therapies in specialised aerosol-challenge in-vivo models. The vaccine evaluation team are internationally renowned and collaborate with the majority of TB vaccine developers world-wide. My particular expertise is in novel vaccine development and evaluation and in aerobiology as applied to in-vivo model development. I provide expertise on in-vivo evaluation of TB vaccines to several international bodies including a major EU-funded TB vaccine consortium and the newly formed TB Vaccine Initiative (a non-profit organization aimed at facilitating new TB vaccine development) and the NIH TB vaccine testing and research materials Contract.
