Martin Austwick completed his undergraduate degree and doctorate in Solid-State Physics at Oxford, before moving into Medical Physics at UCL in 2006. His current research interests involve cancer detection and treatment using light (for example PDT, which uses laser light to activate drugs to destroy tumours). Outside his academic and lecturing work, Martin is a musician, songwriter and podcaster. He has recently started to become involved in public engagement projects at UCL, and is keen to find different ideas as to how to combine his interests in fun and accessible ways.
