Hiroshi Masuhara is Professor at the Department of Applied Physics of Osaka University.
After his PhD at Osaka University in the laboratory of Professor Mataga,an international figure of ultrashort laser pulses spectroscopy, he was appointed Professor at Kyoto Institute of Technology in 1984, and at Osaka University in 1991.
His research fields are time- and space-resolved spectroscopy and photochemistry, nonlinear photochemistry and nano-manipulation of living cells by the radiation pressure of a focused laser beam. He is one of the pioneers of “femtochemistry”, i.e. the use of a few femtosecond laser pulses for the modification of organic materials, superficially or inside the bulk, associated with time- and space-resolved observations of these phenomena.
He directed a major national project on microphotoconversion (Exploratory Research for Advanced Technology, ERATO). In 2006, the international community of photochemists honoured him with the Porter Medal.
He has continuous scientific relation with PPSM laboratory at ENS Cachan, sharing publications and exchanging researchers and PhD students.
