**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 CO~2~ 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.

Subrata Ghoshroy was born in India and grew up in Calcutta. He attended
Jadavpur University in Calcutta and graduated in1970 with a Bachelor of
Electrical Engineering degree with Honors. He migrated to the United
States in 1971 and has been living here continuously since then and
became a Naturalized US Citizen in 1987. He obtained master\'s degree in
electrical engineering from Northeastern University, Boston,
Massachusetts in 1973 and in public policy from the University of
Michigan, Ann Arbor, Michigan in 1975. Mr. Ghoshroy is married to Sreela
Ghoshroy, who is a physician with the Veterans Administration Medical
Center in Boston. They have one son Rittick (Ricky) - a senior at the
Roxbury Latin School in Boston.
