Darragh Murnane

University of Hertfordshire

Darragh is theAssociate Dean for Enterprise in the School of Life and Medical Sciences at the University of Hertfordshire, where he also carries out his research in the Centre for Topical Drug Delivery and Toxicology (TDDT). He trained as a pharmacist initially, gaining a BSc. (Pharm.) from Trinity College Dublin and then a PhD in Pharmaceutical Technology from King’s College London.


Darragh’s research focuses on improving drug delivery products for topical administration of medicines to patients, particularly for inhaled aerosol therapies. In TDDT the research collaborations revolve around developing an understanding of how inhalable particles can be manufactured and processed such that a stable formulation and product can be developed. Through academic and industrial collaboration, he also investigates the factors affecting on-demand generation of a therapeutic aerosol by the patient. This involves assessment of the biological exposure behaviour and responses after inhalation, and the development of advanced analytical techniques to assess product performance and use by patients.
