Area of Focus

  • OPEN POSITIONS: Postdoc fellowship positions are available in Prof. Qingguo Xu's lab. Passionate and driven researchers with a strong background in polymers, biomaterials, nanomedicine, drug delivery or other biomedical research are welcome to apply. Qualified applicants are asked to submit a cover letter with a brief description of research experience, interests and career goals (2 pages), a CV, and contact information for three references to qxu@vcu.edu. The positions will remain open until filled.
  • PhD candidates: We are welcoming self-motivated, talented PhD student candidate for our Pharmaceutical Sciences (PhD) program. VCU pharmacy ranks #17 by US News, and the PI has active NIH (R01) and FDA-funded nanomedicine / drug delivery research program. PhD students will get comprehensive training in translational nanomedicine.
