+### Mark Sinclair
+<br/>
+I am a systems developer and experienced university teacher in computer science and telecommunications, with research interests in computational intelligence and network design. I was committed to the development of higher education in Cambodia over eighteen years, including co-founding an MSc, two university departments and a software house.  After three years at Northumbria University as Assistant Professor in Computer & Information Sciences, I moved to CAP (Christians Against Poverty) as a systems developer.  Following financial difficulties at CAP, I took voluntary redundancy, and alongside phased retirement, have subsequently had three fixed-term contracts as an MSc Project Supervisor in Computing Science at the University of Glasgow; Academic Mentor in Computer Science at NPIC (for SIL in Cambodia); and now as Senior Software Developer for SIL in Cambodia.
+
+I have a BA and MA in Electrical Sciences from Pembroke College, University of Cambridge; an MSc in Telecommunication and Information Systems, and a PhD in Electronic Systems Engineering from the University of Essex.  I am a Chartered Engineer, a member of both the IET and IEEE, and a Fellow of the Higher Education Academy.  I am a Visiting Professor of Computer Science at NPIC in Cambodia.
+
+I am married, with two adult children, and two cats.  I love playing computer games, reading science fiction and fantasy novels, going to the cinema and theatre, and am an active member of my local church.
