Atul Gurtu
Atul Gurtu was born in January 1946. He received the M.S. degree with honors in physics in 1966, and the Ph.D. degree in physics, in 1971, from Panjab University, Chandigarh, India. He joined Tata Institute, Bombay (now Mumbai) in 1969. His fields of research are experimental particle physics, starting with emulsion technique, then bubble chambers, hybrid bubble chamber + spectrometer experiments at CERN, FNAL, for study of strange and charm particles. From 1983, he group joined L3 experiment at CERN. His physics interests at LEP are Z lineshape, search for Higgs, electroweak fits, W mass/width determination. Gurtu is a Member of LEP ElectroWeak Working Group, and of Particle Data Group, and he is responsible for W/Z sections (along with Professor Carlo Caso). In 1993, he group joined CMS experiment, was involved in fabrication of plastic scintillator-based detectors for outer hadron calorimeter in India, and was India-CMS spokesperson since 2003. He was a Scientific Associate at CERN during 1971-1972, 1977-1978, 1984-1985, 1991-1992, and 2001-2002; and he was elected to Indian Academy of Sciences, Bangalore, in 1996.
