Nigel Davies graduated in Pharmacy (BPharm, Hons) from The University of Wales College of Cardiff in 1985. After his internship year, to obtain his professional qualification (MRPharmS), he returned to the University of Wales College of Cardiff to undertake his PhD degree in the area of Pharmaceutical Sciences and in particular investigating improved systems for ophthalmic drug delivery.
This was followed in 1990 by a Postdoctoral Research Fellowship, firstly at the Pharmacy School, University of Queensland, Brisbane, Australia and then at the University of Otago, Dunedin, New Zealand. His post-doctoral research involved developing rapid-onset delivery systems for oral administration and strategies to improve the ocular bioavailability of poorly-water soluble bioactives. He took up a lectureship position at the School of Pharmacy, University of Otago in 1993 and was promoted to Senior Lecturer in 2000. During his time at Otago, he was involved in the development of the "Formulation and Delivery of Bioactives" research theme which was later recognised by the University of Otago as an area of research strength within the University. In 2002, he moved back to the Pharmacy School at University of Queensland as a Senior Lecturer.
