Dr. Ganesh Natarajan
Ph.D, 2006, Aerospace Engineering

Dr. K. Sivan graduated from Madras Institute of Technology in Aeronautical engineering in 1980. He took his ME in Aerospace engineering from 11Sc, Bangalore in 1982. Subsequently, he completed his PhD in Aerospace engineering from IIT, Bombay in 2006. He is currently the Director of Vikram Sarabhai Space Center in Thiruvananthapuram.

During his career at ISRO, he has held many responsibilities like Project Director, Re-usable Launch Vehicle – Technology Demonstrator (RLV-TD); Project Director, Geosynchronous launch vehicle project (GSLV); and Director, Liquid Propulsion Systems Centre (LPSC). He has more than 30 years of experience in the systems engineering of space transportation system, of leading diverse project teams for large and complex projects, of technology development and infrastructure set-up for ISRO’s launch vehicle programs.


Dr. Sivan has contributed significantly in PSLV, GSLV and GSLV Mk-111 vehicle design. He is the chief architect of 6D trajectory simulation software SITARA and Day of launch – wind biasing strategy for launch vehicles; Failure analysis and design improvements in GSLV launch vehicle; Flight testing of indigenous cryogenic stage; Design improvements in GSLV Mk111 launch vehicle and evolved cost-effective strategy for Mars Orbiter Mission (MOM) using PSLV. He made significant contribution in RLV-TD vehicle design; Auto-pilot design of RLVTD and revived GSLV program after two consecutive failures. He implemented strategy for upper stage (PS4) restart capability for PSLV which improves mission versatility by injecting different payloads in different orbits in a single mission; SCRAMJET engine flight test; Re-usable launch vehicle technology demonstrator (RLV-TD) flight test; Established Mission Synthesis and Simulation Facility, Parallel computing facility and Hypersonic Wind Tunnel Facility and initiated technology development program for Electric propulsion, Li-lon cells, advanced avionics etc.

Special Memories

I have vivid memories of lengthy interactions with professors and other faculty members who were friends, philosophers as well as guides. The professors at IIT Bombay not only honed my professional knowledge but also helped in improving my communication skills. I could also relate to the abundant greenery of the IIT Bombay campus.
