Phone: 209.946.2074


BSc, University of Stirling, Scotland, 1983

MSc, University of London, England, 1985

PhD, University of Dundee, Scotland, 1992

Post-graduate in Neurological Science, University of London

Post-graduate in Pharmacology, University of Dundee

Post-Doc in Neuroscience, University of California, Irvine

At Pacific Since: 2002

Robert F. Halliwell, PhD earned a bachelor of science from University of Stirling in Scotland and a master of science from University of London in England. He earned his doctor of philosophy from University of Dundee in Scotland. Dr. Halliwell completed post-graduate training in neurological science at University of London, in pharmacology at University of Dundee and short-term training at the Rockefeller University, the London School of Pharmacy and Universidad Nacional Autónoma de México. Before coming to Pacific he was a Research Fellow at University of California, Irvine. He joined the Pacific family in 2002.

Dr. Halliwell considers himself very fortunate and privileged to teach Pacific's pharmacy students because they are bright, hard-working and respectful. Dr. Halliwell's area of expertise is neuroscience in the context of clinical pharmacology. He is actively involved in the International Brain Research Organization. Dr. Halliwell gives community seminars and lectures on healthy brain aging and the potential value of stem cells in drug discovery and regenerative medicine. He is also on the Medical Ethics Committee at Dignity Health and the advisory board for the Wellness Center of San Joaquin.

Although he is English, the majority of his education took place in Scotland. He is learning to play the guitar as a left-hander, loves trail running and enjoys riding his 2015 Harley-Davidson Street Glide.


Teaching Philosophy: "If I make it interesting and sometimes fun, we all learn together."


PHRM122 - Physiology & Pathophysiology I
PHRM 146 - Therapeutics I Neuropsychiatry
PG220 - Pharmacology (DDS)


Research Summary: "Our lab is addressing the properties and potential value of neurons derived from a variety of human stem cells for studies in neuropharmacology and neurotoxicology; I have also published work in the history of medicine."
