# Jason Crain

Jason Crain (born August 24, 1966) is an American physicist based in the United Kingdom. He was appointed to IBM Research in 2016. He previously held the chair of applied physics at the University of Edinburgh in Scotland and was appointed Director of Research at the UK's National Physical Laboratory (NPL) in London (as of 2015) where he also held the role of Head of Physical Sciences (since 2007). He was also Visiting Professor at the IBM TJ Watson Research Center in New York. His background is in the structure and physics of disordered matter at the molecular scale with a view to applications.

## Early life

Born on August 24, 1966, in New York City, he obtained his undergraduate degree from the Massachusetts Institute of Technology in 1989, receiving the 1988 Orloff Prize for Research.

## Career

Crain was a research scientist at Fujitsu in Japan (1990) as one of the first interns of the MIT-Japan exchange programme. He obtained his PhD from the University of Edinburgh in 1993. Crain was appointed to a Royal Society of Edinburgh Research Fellowship in 1995, and then appointed to the academic staff at Edinburgh, where he held the Chair of Applied Physics until 2016. He was elected Fellow of the Institute of Physics in 2002. He was then appointed as Head of Physical Sciences and Director of Research at the National Physical Laboratory from 2007 to 2016, at which point he was appointed to IBM Research. He holds appointments as Senior Visiting Fellow at the National Nuclear Laboratory (from 2015) and Visiting Professor at the University of Oxford (from 2018). He has pioneered novel electronic structure methods for materials simulations and led research programs which combine AI, physical modelling and quantum computation.
