I have an interdisciplinary background comprising Computer Science, High Energy Physics (HEP), and Nonlinear Optics. I have worked in two experimental collaborations of physicists, CLEO (Cornell) and OPAL (CERN), and have authored and co-authored over 100 research papers. But the following lists of publications and invited talks are a good representation of my contribution to physics research:
In Nonlinear Optics, I studied the propagation of very high intensity electromagnetic waves in nonlinear media such as optical fibers in form of optical solitons. I constructed and solved the equations governing this highly nonlinear dynamics.
My research work in HEP has been in testing the quantum theory of nuclear force known as Quantum Chromodynamics (QCD). I conducted my doctoral research while working on the OPAL experiment at CERN. My work contributed to what is now known as the first clear experimental evidence in support of a salient feature of QCD that the strength of nuclear force between the nuclear particles decreases as the particles get closer, the so called Principle of Asymptotic Freedom. At CERN, I also managed the off-line data monitoring of the ZED chamber, a part of the OPAL detector designed to measure z-coordinates of the particle tracks.
I initiated and carried out the tests of QCD during my postdoctoral research work on the CLEO experiment at Wilson Laboratory of Nuclear Studies, Cornell University. There, I also headed the offline data reconstruction efforts for the CLEO collaboration. The complexities in handling these large data sets have given rise to an NSF funded collaborative project, NILE , of computer scientists and physicists in distributed computing. This is a prime example of how the requirements of HEP experiments push on the limits of computer technology. (This is also a reason why you should not ask me: what the heck are you doing here in Computer Science after earning a PhD in Physics?)
