Who is Jack? 
I was a free lance filmmaker but I've returned to my geeky roots and am doing a Computer Science PhD at Imperial College London on "Disaggregating Smart Meter Readings". As a filmmaker, I've worked on over 35 films including roles as producer, director, editor and stills photographer.
My personal website is Jack-Kelly.com
My real name is Daniel but everyone calls me Jack!
The website for a film I produced is here: Mirrors (short film)
