Dear Sir，
I would like to inquire about the position of laboratory research assistant in the field of biochemistry that you advertised in newspaper on December 12.

I am twenty-eight years old. In 1986 I received my M.S. in Chemistry from the University of California. As a student I took many Chemistry and Biology courses a few of which are listed here:

General Chemistry
Organic chemistry
Physical Chemistry
Biochemistry - two years
Analytical Chemistry - both organic and Inorganic
As I was a graduate student, I worked as a research assistant for Dr. John Williams, Professor of biochemistry, University of California. During this time I assisted Dr. Williams in basic research concerning the phosphates cycle in metabolism. I can supply u with a copy of the resulting paper at your request.

Since my graduation I have been employed by Boston university as an assistant professor. I have continued my research in this time, and several of my papers have been published in New York. my immediate superior, Dr. William Larson, has indicated his willingness to provide my with a reference.

I feel that I have sufficient education and experience in my background to fulfill the qualifications for your position. I hope that you will schedule me for an interview at your earliest convenience.

Sincerely yours,
