Dear Sir/Madam

I am a research scientist at the Korea Institute of Biosciences and
Biotechnology. Next year, I will get my doctor degree in virology and
molecular immunology. I have studied molecular biology, virology and
immunology. I want to find a post-doctoral position. Although my studies
have been related to HBV and recombinant antibodies so far, I'd like to
study any work in cellular immunology fields and I have the confidence
to do them well. If anybody has an interest in me, please contact me by
e-mail or Fax. I enclose my CV below. I am just waiting for your
response.

Sincerely yours,

Chun Jeih Ryu, Ph.D candidate
