Areas of Expertise

Survival analysis, clinical trials, observational studies, genomics, equal employment opportunity.

Pan worked/works on the Prospective Payment System project for end stage renal disease patients, Scientific Registry of Transplantation Recipients, Diabetes Prevention Program Outcome Study. She receives the mentored research career award in clinical translational research from NIH during 2012-2014, studying genetic disparity associated with composite microvascular complications in Type 1 Diabetes patients.

Locating in DC, her other reseach area  is statistical issues in legal applications.


Ph.D. 2007, University of Michigan
