He also served as the Director of IFFIT (International Facility for Food Irradiation Technology) of the Joint FAO/IAEA, United Nations (1988–1992).
[9] He gained his DSc in 1973 with a thesis entitled Some Aspects of the Interactions of Fast Charged Particles with Matter which led to his work on plasma redshift.
