(Philadelphia, PA) - Sarah J. Ratcliffe, PhD, has been named Assistant Professor in the Department of Biostatistics and Epidemiology at the University of Pennsylvania School of Medicine.

After earning her BS(Hons) degree in 1996 from the University of Technology in Sydney, Australia, Dr. Ratcliffe went on to receive her PhD from Macquarie University, also in Sydney, Australia.
