Statistics in Physical Engineering Sciences AwardAmerican Statistical Association2018The Statistics in Physical and Engineering Sciences (SPES) Award was originally established in 1990 as the Statistics in Chemistry Award. Its purpose was to recognize outstanding collaborative endeavors between statisticians and chemists. Beginning in 2015, the award’s scope was expanded to recognize excellence in partnerships among statisticians, scientists, and engineers across the many disciplines encompassed by the physical and engineering sciences. Consequently, the award was renamed the SPES Award to reflect this more inclusive scope.
Career Development AwardKorean International Statistical Society2016This award is to recognize statisticians who are in the early stages of their careers and who have demonstrated outstanding productivity and the potential to make significant contributions to the field of statistics.
