Winton Advanced Research Fellow and EPSRC Early Career Fellow
Akshay received his undergraduate degree from St Stephen’s College, University of Delhi in 2006 and his MSc from the University of Sheffield in 2007. He received his PhD from the University of Cambridge in 2011, working in the group of Prof. Sir Richard Friend. From 2011 to 2014 he held a Junior Research Fellowship at Corpus Christi College, Cambridge. As of October 2014 he runs an independent research group at the University of Cambridge and is an EPSRC Early Career Fellow & Winton Advanced Research Fellow.
Akshay's research is focussed on the electronic and optical properties of molecular semiconductors, quantum dots and novel nanoscale structures. He has worked extensively on organic photovoltaics as well as singlet exciton fission in molecular semiconductors, using ultrafast spectroscopy to elucidate the how charge delocalisation, spin and vibrational coherence underlie the physics of these systems. His group is currently interested in areas such as solar energy harvesting in photovoltaics and artificial photosynthetic complexes, molecular spintronics and the photophysics of novel nanoscale semiconductor materials.
