Dr Anton Walsh obtained his B.Sc. and M.Sc. in Physics from N.U.I Cork in 2003. His M.Sc. research focused on “Investigation of non-linear optical properties of π-conjugated organic molecules such as Porphyrins and their derivatives using Z-scan technique”. He was awarded a Ph.D. from University College Cork in 2010, for his study of the time-dependent extinction of diamond-like-carbon nanoparticles formed from the UV photolysis of helium buffered naphthalene. Anton undertook two post-doctoral positions subsequently, the first position at the Astronomy and Astrophysics Department of Leiden University, where he studied the spectroscopy of carbon chain radicals formed in high-pressure pulsed plasma, and the second in the Solar Fuels division of the Dutch Institute for Fundamental Energy Research, where he studied heterogeneous catalysis of vibrationally activated carbon dioxide. His main interest is in the application of spectroscopy for in-situ detection of trace species.
