  I am in the middle of a project to help better diagnose tuberculosis (TB) in India and China. TB still infect around 10 million people mostly in those parts and sadly kills around 1.5 million every year. Diagnostics are currently either inaccurate or very expensive, what I am working on should bring accuracy at a lower price tag, hopefully helping to better diagnose and reduce the numbers above as TB can be easily cured with a antibiotics if detected early enough.
