Laser spectroscopy and photophysics of compounds in gas, liquid and solid phases. Current research is directed towards the following topics: · Applications of cavity ring-down spectroscopy to relevant problems in atmospheric physics/chemistry. · Radical kinetics and trace gas detection. · Light detection and ranging (LIDAR) for aerosol detection.· Development of compact instruments for future field experiments. · Spectroscopy of large organic compounds in seeded supersonic jets. · Investigation of weak forbidden transitions in large jet-cooled aromatics. · Formation of noble metal colloids in suspension using laser ablation. · Third order nonlinear properties of novel materials, including porphyrins and colloidal systems.Experimental techniques employed are: · Cavity Ring-Down Spectroscopy (CRD). · Incoherent Broadband and and single mode Cavity Enhanced Absorption Spectroscopy (CEA). · Laser-Induced Fluorescence (LIF) or Phosphorescence (LIP). · Multi-Photon Excitation (MPE) and Ionization(MPI). · Z-scan method. · Laser ablation and laser induced plasma spectroscopy.  Local Research groups:· Founder and leader of the Laser Spectroscopy Group (Physics Department, UCC) (http://laser-spectroscopy.ucc.ie).· Director and Section Leader in the Centre for Research into Atmospheric Chemistry (CRAC), Chemistry Department, UCC  (http://crac.ucc.ie/).· Member of Research Consortium in the Environmental Research Institute. Lab space allocation on first floor – transfer of equipment in progress.· Strong Affiliation with Materials Group (Chemistry Dept., UCC)
