Dear Ms. LastName,
I am interested in
applying for the scientific research summer internship position that was listed
through the Name Tauxff Career Services Office.
I have had a great
deal of laboratory experience in chemistry, biology, and geology, both indoors
and in the field. In the lab, I have performed chemical reactions and I am
currently using microscopes to observe many specimens. In environmental field
studies, I have conducted outdoor labs to assess water chemistry.
Last summer, I worked
as conservation assistant at XXX National lab. I am seeking to complement this
outdoor experience with a research internship in order to acquire the
background necessary for a future career in scientific research.
I believe that I
would an asset to your program. This internship would provide me with the ideal
opportunity to assist at your organization and to expand my research skills.
I will call next week
to see if you agree that my qualifications seem to be a match for the position.
If so, I hope to schedule an interview at a mutually convenient time. I look
forward to speaking with you.
Thank you for your
consideration.
Sincerely,
Signature
