Ji Lab Is Looking for New Postdoc Fellows

POSTDOCTORAL POSITION available for cancer biochemistry and chemical biology studies. We are looking for enthusiastic, highly self-motivated Ph.D. and/or M.D. fellows with strong laboratory skills in biochemistry and structural biology. The project involves the determination and characterization of highly selective small-molecule inhibitors for the crucial signaling pathways that are linked to tumorigenesis. Our ultimate goal is to provide novel targeted therapies for cancer. Submit CV and statement of research experience via email to Dr. Haitao (Mark) Ji (Haitao.Ji@moffitt.org). Recommendation letters will be requested when needed.
