Research summary

Dr Murray researches nucleation and crystallisation throughout the Earth's atmosphere, in collaboration with aerosol and cloud modellers. Major areas of research include:

  • Ice nucleation on solid particles such as mineral dust, soot and biogenic materials

  • Crystal structure and properties of ice which forms under atmospherically relevant conditions

  • Aircraft- and ship-based measurements of ice nuclei

  • Global modelling of ice nuclei distributions

  • Glass formation and the role of other amorphous solids in the Earth's atmosphere

  • Nucleation crystallisation from solution droplets

  • Cryopreservation (including knowledge exchange with industrial partners)

  • Efficient descriptions of ice nucleation for use in cloud models

  • Formation of crystalline acid hydrates in stratospheric clouds

Biography

Ben graduated with a First-Class MChem Honours degree from the University of Wales, Swansea, in 1999. This included a period spent working in Professor M. A. Tolbert’s research group at the University of Colorado in Boulder, USA, where he worked on phase changes in atmospheric aerosols. Following this, Ben undertook a PhD at the School of Environmental Science at the University of East Anglia where he worked on heterogeneous chemistry in mesospheric ice clouds.

Ben then moved to Vancouver, Canada, in 2004, for a post-doctoral fellowship with Professor Allan Bertram at the University of British Columbia, researching phases of ice in the Earth’s upper troposphere. Returning to the UK in 2006, he took up a permanent academic position at the University of Leeds in the School of Earth and Environment, where he is Reader in Aerosol Science.
