Diana Marangu will talking about her current work on TB in Nairobi County. *Abstract:*. My proposed PhD work focuses on identifying barriers, facilitators and potential solutions to TB contact investigation in Nairobi County in Kenya. This formative research will inform the design if implementation tools to address barriers in TB contact insuring the proposed solution is in line with country and global efforts towards zero TB deaths, infections, suffering and stigma. The tools I propose are hoped to tackle stigma, sub-optimal patient education and inefficient documentation which are potentially modifiable barriers. The technological piece is a computerized contact register and mobile phone follow-up platform. *About the speaker:* Diana Marangu is a paediatrician and tutorial fellow at the University of Nairobi, Kenya.
