Former research Interests:

Here are some materials about the work I carried out at the University of Leeds (England) under the supervision of Prof Geoff R. Davies. This work was mainly about relaxations in Poly Vinyl Methyl Ether. It is the sequel of a work undertaken by a former PhD student Dr Cherdsak Saellee in the IRC laboratory at the University of Leeds. Chersak studied the rotations of the methyl group in PVME. My work was essentially the rotation of the methoxy group in PVME. My thesis also contains a small section about relaxations in Polyethene.

Abstract and Poster:

My PhD abstract
Here is a poster, I presented to the ccp5 conference in September 2004. It does not contain the most up to date results, but the essential is there. The thesis contains more recent results.
