Akshay is Professor of Physics at the Cavendish Laboratory, University of Cambridge. He obtained BSc from St Stephen’s College, University of Delhi, in 2006 and MSc from the University of Sheffield in 2007. He completed his Ph.D. from the University of Cambridge in 2011, following which he held a Junior Research Fellowship (JRF) at Corpus Christi College, before establishing his independent research group in 2015. He was awarded the Henry Moseley Medal and Prize of the Institute of Physics for “exceptional early career contributions to experimental physics” and has also been awarded an EPSRC Early Career Fellowship and ERC grants.

He is the co-founder of Cambridge Photon Technology and Illumion.


Our vision is to catalyse a new era in the study of energy and quantum materials by elucidating the fundamental electronic, structural and transport dynamics of these materials with unprecedented spatial and temporal precision. We seek to provide fundamental insights into these materials and use these insights to develop strategies and device concepts that can bring radical new functionalities beyond current physical limits.
