motivation letter for phd

can somebody proof-read this motivation letter and suggest any possible corrections/additions.

Dear Prof.
I wish to apply to the PhD project “ABC” in your lab for the DEF International Doctoral Program. I believe that this doctoral degree would be a stepping stone to fulfil my ultimate goal, which is to delve into research, which would provide pragmatic solutions to societal problems.
I am a pre-final year postgraduate student at the Indian Institute of Technology (IIT) Guwahati, one of the premier institutes for engineering and applied sciences in India. I am pursuing two year Master of Technology (M.Tech.) programme in the Department of Biotechnology. I expect to complete my degree in May, 2014.
Presently, I am working on my thesis in Structural Biology and Molecular Biology laboratories under the supervision of Dr. X and Dr. Y. The objective of this project is to study the structural mechanism of inhibition of proteinX by drugY. I did Docking and Molecular Dynamics simulations to elucidate the kinetics behind inhibition of proteinX by drugY. Now I am trying to clone the proteinX gene and consequently express the protein. Post expression, I would attempt to purify the protein and co-crystallize it with drugY. The structure will be corroborated with the computational data and used to study the underlying molecular mechanism of inhibition.
My experience over the past one year has inculcated in me a great interest in Structural Biology and I would ideally like to pursue this in a PhD program. I am particularly interested in this project because of its relevance to medical conditions. I firmly believe that while clinicians have the opportunity to help people directly, they cannot do so without scientists and researchers.
The quality of the faculty, flexibility of the graduate program, the diverse areas of ongoing research, the carefully designed depth and breadth of courses, cultural diversity in Institut Pasteur along with world-class equipments and facilities, seem to me as the right ambience to nurture my research interests and work towards my goal. It would be a matter of great pride for me to be a part of this rich interdisciplinary interface. It would aid in my intellectual growth and academic development. The institute will offer me a very conducive atmosphere for research and development.
Following my PhD, I hope to be part of a reputable research university where I will continue my research and endeavour to perpetuate my enthusiasm for science by motivating my students.
Thank you for considering my application, and I look forward to your acceptance.

Sincerely yours,

XYZ.
