Tamás Keszthelyi holds an M.Sc. degree in chemical engineering (Technical University, Budapest, Hungary) and an M.Phil. degree in chemistry (University of Southampton, United Kingdom). He received his Ph.D. from he University of Copenhagen, Denmark in 1996, for work carried out at Risø National Laboratory. Following a postdoctoral appointment at Risø National Laboratory and a three-year stay at Aarhus University (Denmark) as assistant research professor, in 2001 he took up a permanent position at the Chemical Research Centre in Budapest, Hungary. In July 2017 he joined the staff of Wigner RCP as senior research scientist.
He is an experimentalist and worked with several conventional and laser-based, linear and non-linear spectroscopic methods, stationary as well as time-resolved. He has experience in the operation of pulsed ns, ps and fs lasers, with non-linear optics, spectroscopic, cryogenic and ultra-high vacuum equipment. Additionally he also gained substantial expertise with the theoretical methods of high-level quantum chemistry.
