Biographical Profile
Professor Ramzan obtained his undergraduate training in Pharmacy in New Zealand and his post-graduate training from the Department of Pharmacy at The University of Sydney where he obtained his Master of Science and PhD degrees specialising in Drug Pharmacokinetics and Pharmacodynamics.
Professor Ramzan spent five years at the State University of New York at Buffalo in the Department of Pharmaceutics where he carried out postdoctoral training under the guidance of Distinguished Professor Gerhard Levy. He also held Faculty appointment at the same institution and also was Assistant Professor of Pharmaceutical Sciences at the School of Pharmacy at the University of Pittsburgh. Professor Ramzan returned to Australia in 1989 where he has held academic positions as Lecturer, Senior Lecturer, Associate Professor and now as Professor.
Professor Ramzan is an author/co-author of 100 research publications mainly in the areas of pharmacokinetics, pharmacodynamics, drug assays and drug metabolism.
In 2000 Professor Ramzan was appointed an Associate Dean in the Faculty of Pharmacy, The University of Sydney, with responsibility for admissions. Professor Ramzan is a registered pharmacist.
In June 2005 Professor Ramzan was appointed Acting Dean and is currently the Dean of Pharmacy. In December 2005 Professor Ramzan commenced his 18 month term as Fellow of University of Sydney Senate elected by the University's academic staff.
In February 2008 Professor Ramzan was formally appointed Dean of the Faculty of Pharmacy.
