Biographical sketch of Subrata Ghoshroy
Subrata Ghoshroy has been a Senior Defense Analyst at the Government Accountability
Office (GAO) since 1998. He is currently on a leave of absence from GAO and is
working as a research associate in the Science, Technology, and Society Program at the
Massachusetts Institute of Technology, where he is leading a project called Promoting
Nuclear Stability in South Asia. In addition, he is conducting research on space weapons
and international space cooperation.
Mr. Ghoshroy was a Senior Fellow at the Belfer Center for Science and International
Affairs at the John F. Kennedy School at Harvard University from September 2002 to
December 2003 on a sabbatical from GAO. During this time, he conducted independent
research on weaponization of space and edited a book entitled Ensuring America’s Space
Security, which was published by the Federation of American Scientists in October 2004.
In his seven years at GAO from 1998 to date, Mr. Ghoshroy had contributed to a number
of important assignments including two reviews of the controversial airborne laser
program, transformation of military communications system, joint tactical radio, future
combat systems, and the ballistic missile defense programs. He was the lead investigator
for the GAO team which found that the infrared sensor in the missile interceptor of the
national missile defense system had failed in a critical test called the Integrated Flight
Test (IFT)-1A. He received several awards for his contributions to reviews involving
complex technical issues.
Immediately before joining GAO, Mr. Ghoshroy served as a professional staff member of
the House National Security Committee from 1997 to 1998, where he was responsible for
monitoring and evaluating budget and policy matters related to Military Research and
Development (RDT&E) using his expertise to carry out comprehensive evaluations of
complex weapons systems that incorporate state-of-the-art technology.
Mr. Ghoshroy was awarded a Congressional Fellowship by the Institute of Electrical and
Electronics Engineers (IEEE) in 1996. He spent his Fellowship year as a professional
staff member of the House International Relations Committee with responsibilities for a
broad range of issues that included non-proliferation, arms control, ballistic missile
defense, the Comprehensive Test Ban Treaty, nuclear weapons stockpile stewardship, laser
weapons, chemical weapons demilitarization, and landmines ban.
Prior to his transition to the policy world, Mr. Ghoshroy was for 20 years an engineer and
an engineering-manager developing high-power laser, electron beam, and pulse power
technologies for plasma fusion, high-energy accelerators, and military lasers. He has a
highly successful track record in managing sophisticated, interdisciplinary teams to develop
advanced technology for DOD, DOE, and NASA. For example, he developed novel
discharge sources for ultra-violet preionization of CO2 lasers and pulse-forming networks
for ultra fast switching circuits for discharge lasers. In 1994, Mr. Ghoshroy led a project
called Laser Atmospheric Wind Sounder (LAWS) sponsored by NASA to develop the first
high-power laser for satellite-based measurement of wind speed.
Mr. Ghoshroy has published a number of papers in his technical field and authored and co-
authored many technical reports. He has also published articles on the federal science
policy, defense conversion, and nuclear weapons in South Asia. He is a frequent public
speaker on science and Congress, arms control, missile defense, and nuclear weapons.
