K. Sivan, who previously served as director of ISRO’s Vikram Sarabhai Space Centre since June 2015, succeeded A S Kiran Kumar. Like his predecessor, Sivan has been appointed to a three-year term. Sivan also serves as secretary of the Department of Space and chairman of the Space Commission.
Sivan joined ISRO in 1982, working on the PSLV booster program. He is credited with turning around the troubled GSLV Mark II rocket program after a series of launch failures.
Sivan graduated from Madras Institute of Technology with a degree in aeronautical engineering in 1980. He earned a master of engineering degree in aerospace engineering at the Indian Institute of Science two years later. In 2006, he was awarded a Ph.D. in aerospace engineering by the Indian Institute of Technology in Bombay.
