Jon Marangos graduated with a BSc in Physics from Imperial College in 1982 where he remained for his PhD completed in 1986. In 1990 he was appointed an EPSRC Advanced Fellow during which time he was a Visiting Researcher at NIST, Gaithersburg USA and a Visiting Professor at the University of Tokyo. He was appointed a Lecturer in Physics at Imperial in 1995 and a Reader in 1999. In 2002 he was made Professor of Laser Physics and subsequently appointed to the Lockyer Chair in Physics. Currently he is the Director of the Blackett Laboratory Laser Consortium having served as the Head of the Quantum Optics and Laser Science Group from 2003-2008. He is the Principal Investigator of the EPSRC Programme Grant "Attosecond Electron Dynamics in Molecular and Condensed Phase Matter" (starting 2011) and has been awarded an ERC Advanced Grant on "Attosecond Science by Transmission and Emission of X-rays (ASTEX)" (starting 2012).

His major areas of research activity are in: (1) development of experimental methods for the measurement of processes on the attosecond time-scales; (2) non-linear optical processess for generation of coherent soft X-ray and VUV radiation and applications of these sources in atomic, molecular and muon physics; (3) High intensity laser- matter interactions especially looking at interactions with molecules and clusters; (4) investigation of atomic and molecular coherence effects (e.g. EIT) and enhanced non-linear frequency mixing. Recently he has been looking at the problems of controlling the electron dynamics driven in complex systems by strong laser fields and in developing high power sub-femtosecond light sources.  He is involved in free electron laser science having led the UK New Light Source Project from 2008-2010 and is an active participant in experiments at LCLS, SLAC, USA and FLASH, DESY, Hamburg. He is a Fellow of the Optical Society of America and the Institute of Physics.
