Laboratory for Scientific Computing


Martin Braithwaite studied Chemical Engineering at Imperial College,
London. He received a PhD in molecular energy transfer in Physical
Chemistry at the University of Cambridge. This was followed by
post-doctoral fellowships at the Universities of British Colombia and
Southern California as well as at JILA (NIST/ University of Colorado,
Boulder) in energy transfer and laser-induced chemistry.

From 1978 he worked from Imperial Chemical Industries in the UK as Company
Research Associate covering aspects of chemical reaction engineering,
process safety, explosion and detonation science.

Subsequently, Martin held the William Penney Chair of Chemical Physics at
Cranfield University in addition to being a visiting professor at TU Delft,
Imperial College and the University of Queensland. He has been an academic
visitor in the Laboratory for Scientific Computing since 2013.

*Professional** interests*

*Martin’s recent research has focussed on condensed phase detonations in
heterogeneous explosives. He is an active consultant in this field as well
as explosives safety issues. Industrial clients have included AEL, AWE, **BHP,
**BME, **CSBP, **De Beers, **Downer, Dyno, Johnex, Lucite, **Orica **& Rio
Tinto as well as an expert witness role in cases involving ammonium
nitrate. He is an Associate and Expert Panel member of SAFEX.*
