Two Postdoctoral or Visiting Scholar positions are available to (1) study the mechanism of breast cancer metastasis and develop novel therapeutic strategies for treating metastatic breast cancer; and (2) investigate the epigenetic mechanisms of chemical carcinogenesis. These projects will use cell culture and mouse models to investigate the epigenetic mechanisms (DNA methylation, histone posttranslational modifications and non-coding RNAs) of breast cancer metastasis and chemical carcinogenesis. Candidates should have a recent Ph.D. degree with strong background in cell/molecular biology and cancer biology. Experiences in studies on cancer epigenetics, non-coding RNAs, and cancer stem cells with skills in handling mice, producing tumors in mice and treating mice with commonly-used drug administration approaches would be advantageous. The expected qualifications of candidates include: be highly self-motivated with strong interest in learning new knowledge and techniques; have excellent communication and organizational skills and attention to details, be capable of conceptualizing, designing experiments and conducting studies independently as well as cooperatively with other lab members as a team; and have the capability to write manuscripts for quality publications. Compensations including salary and benefits will be highly competitive depending upon candidates’ qualifications. Interested applicants, please send a cover letter describing your research training experience, a brief statement of your research interest, scientific achievements and future career goal, curriculum vitae (CV) and contact information (names, e-mails, and telephone numbers) of three references to: Dr. Zhishan Wang (email@example.com) or Dr. Chengfeng Yang (firstname.lastname@example.org), Department of Toxicology and Cancer Biology, University of Kentucky, Lexington, KY 40536. Only short-listed applicants will be contacted for interview. These positions will be open till filled.
