I joined
the Department of Computer
Science
at Bath University in 2007, where
I hold
a Royal
Academy of Engineering/EPSRC Research Fellowship. I am a part of the Media
Technology Research Centre, which has interests spanning Animation,
Visual Interpretation and Digital Effects. I
received a BSc in Computer Science with Honours from Cardiff University in 2001, and a
Ph.D in Computer Science from Cardiff University in 2006. My thesis
explored the synthesis and perceptual analysis of visual speech. I am
also a visiting researcher at the Centre
for Vision, Speech and Signal Processing (CVSSP) at Surrey University.
My
research interests lie in the convergence of Computer Vision, Computer
Graphics and Psychology - particularly in relation to human motion
analysis and synthesis.
EPSRC Network on Vision and Language
EPSRC
has just awarded funding for a new network on Vision and Language. The
first newsletter - which includes more information - may be found here.
BMVA Symposium of Facial Analysis and
Animation
The BMVA
Symposium on Facial Analysis and Animation was held in Edinburgh on
June 10th. Details on the even can be found at http://www.cstr.ed.ac.uk/faa/.
EngD in
Digital Entertainment
There are
currently multiple EngD opportunities
in our research group in the area of Digital Entertainment, including
movie effects post-production and video games. An EngD is a 4 year
degree based primarily in Industry on a problem jointly supervised by
both Industry and Academia. There are currently EngD opportunities with
a number of internationally leading companies, including Lionhead, Bizarre Creations, Framestore, Frontier and Naturalmotion. An EngD gives
you the perfect opportunity to work on cutting edge problems with both
significant Industrial and Academic relevance.
You can
find
out more details at our current
EngD website, or you can send me an email if you are interested in
applying or finding out more.
