Prof. Rajaraman is co-chair of the International Panel on Fissile Materials. He obtained his Ph.D. from Cornell University in 1963 under the supervision of Prof. Hans Bethe. He has taught at Cornell University, the Institute for Advanced Study at Princeton, the Indian Institute for Science, Harvard University, M.I.T, Stanford University and CERN. His physics research has spanned nuclear theory, elementary particle physics, quantum field theory, statistical mechanics, solitons and quantum Hall systems. In addition he has also been working on nuclear arms control. In collaboration with colleagues at Princeton University, he has worked on a variety of nuclear issues in South Asia, including de-alerting, early warning and missile defense, nuclear weapon accidents, etc.

He has studied in depth the Indo-US nuclear agreement. Finally he has made research on fissile material production in India and Pakistan and the prospects for FMCT and CTBT in South. Asia.
