My name is XX. I am a Ph.D candidate at XXX University, under the supervision of Professor XX. Recently, there has been a problem with our email system, so I apologize if this is not the first time you have received my letter. I am writing to you as I would like to continue my research under your supervision and as part of your team via the XX program.
I have worked for Dr. XX in the Computer-Aided Drug Design (CADD) team for three years. My research project is XXX and is supported by the National Natural Science Foundation of China. I have XXX. I have published my research results in XXX etc.
My goal is to obtain a joint Ph.D from both XX and XX University through the XX program and the Chinese National Fund (a fund that supports Chinese Ph.D candidates to study at world class universities and ensures all of their costs of living are met while studying abroad). In order to be a successful applicant, I need an official letter of invitation from you to join your research team by the Chinese application deadline of January, 2010. Please find enclosed my CV.
Thank you for considering making me a member of your research group. I look forward to receiving your response by the end of December.
