I have established an international reputation in my field of expertise, "Inhalation Drug Delivery and Pulmonary Biopharmaceutics". The aim of this field of scientific endeavour is to describe the behaviour of drug and biological molecules following their administration to the lung as inhaled aerosols. The field has become increasingly important over the last 20 years as the incidence of lung-related diseases and the morbidity due to these conditions is increasing a more than 5% per year. My research is primarily preclinical using both cell and animal models, which allows a wide array of discovery and development works. The technical expertise of my laboratory ranges from pharmaceutics to pharmacokinetics, pharmacology, physiology, cell & molecular biology to pathology and immunocytochemistry. Recently, we started multidisciplinary, translational investigations into the role that drug transporters play in the pathogenesis of tobacco-related chronic obstructive pulmonary disease (COPD). Previously, we have been successfully developing the following research projects: - Lung cellular disposition of inhaled beta-2 agonists for asthma therapy - Investigation of drug transporter expression in proximal and distal lung - Characterisation of delta-ENaC expression and function in airway epithelia - Determination of the role of OCTN1 in tobacco smoke-related COPD - Novel lipid-based drug delivery systems for pulmonary delivery of sCT I am an internationally recognised leader in the field of in vitro models of respiratory epithelial barriers and my laboratory has been credited with pioneering work on the development of primary cultures of human alveolar epithelial cells. The unique combination of cell physiological basis and pharmaceutical application has lead to numerous research collaborations, nationally and internationally, as well as to a continuous stream of visitors to my laboratory. I am PI of TBSI and an SFI Strategic Research Cluster - the Irish Drug Delivery Network (commenced December 2007), which brings together expertise from several leading academic institutions (UCD, UCC, RCSI and TCD) and a number of Irish drug delivery companies.
