Authored or co-authored more than 30 refereed and more than 150
non-refereed publications and participated in the writing of several
review documents for the WMO and a report for the National Academy
of Sciences. Also lectured cloud physics and weather modification
courses at the University of Arizona and the University of Witwatersrand
in Johannesburg, South Africa. Supervised several post-graduate
students from universities around the world over the past five years
and continues to do so.
