    Max Wallis wrote a PhD thesis on Cometary Plasma at Manchester University (PhD 1966) and held research posts at Stockholm, Liege and Oxford before moving to Cardiff in 1979.

    He has been a Visiting scientist at the Max-Planck Institue for Aeronomy on several occasions; Guest Observer at ESA's Villafranca (Madrid) station, 1980-91, using the satellite-borne IUE telescope for comet studies.

    He has worked as Co-investigator and Science Working Team member for the European Space Agency's Giotto Mission 1980-86 with periods working at the European Space Technology Centre (Netherlands), UCL's Mullard Space Science Laboratory, the Rutherford-Appleton Laboratory and the University of Kent Space Science Laboratory.

    Science Interests
  • Space Science; comets and minor bodies - structure and formation
  • Planet evolution inferred from rare gas and isotope fractionation
  • Radiative properties of mesospheric dust particles and their contribution to the astmospheric greenhouse
  • Collisional processes and catastrophic changes in the solar system
  • non-linear optics in the stochastic electrodynamics formulation
