Jasper Kirkby is a British experimental particle physicist working at CERN.
He has led large particle accelerator experiments at SPEAR and the Paul Scherrer Institute.
He completed his degrees in Oxford and London, then spent twelve years at Stanford University before joining CERN in 1984.
In 1972, he received a Ph.D. degree in high energy physics from Westfield College in London, United Kingdom.
[5] Kirkby et al. published the results of CLOUD's first experiment in the journal Nature in 2011,[6] reporting that cosmic rays "seemed to enhance the production of nanometer-sized particles from the gaseous atmosphere by more than a factor of ten."
