Currently Executive Editor for Advanced Drug Delivery Reviews, a journal publishing high quality thematic reviews on a wide range of Advanced Drug Delivery topics.

Also on the editorial board of the Journal of Drug Targeting and International Journal of Nanomedicine.

I have published over:

90 full-length peer reviewed research publications 20 journal series, authored textbook chapters or edited books 116 conference abstracts or editorials. I have supervised 25 successful PhD students and 24 postdoctoral/visiting scientists.

I have served on a number of pan-European scientific steering committees in drug delivery and as organiser/ scientific programme organiser for International scientific meetings. I also serve as a consultant to pharmaceutical industry in USA and UK and is Director of Research at the School of Pharmacy and Pharmaceutical Sciences, Cardiff University.

Hypothesis-driven science surrounding issues at the interface between the nature of biological barriers and experimental therapeutics.

The laboratory maintains a wide range of techniques ranging from cell and molecular biology through to ex-vivo and in-vivo models to address the scientific issues.

There are two principle areas within the laboratory's research strategy: blood-brain-barrier and in the developing area of brain tumour research.
