Research Interests: Understanding the disparity between matter and anti-matter, the origin of mass (search for higgs particle), and how the current universe evolved from the big bang. 

Biography: Dr. Shabana Nisar is an experimental particle physicist with a Ph.D. from Syracuse University, USA. She did her masters in physics from Punjab University in 2002. She then left for USA, to pursue her doctorate studies, which she completed at the age of 26. She was an active member of the CLEO experiment at Cornell Electron-positron Storage Ring (CESR) located at Cornell University in Ithaca, NY, where she studied the very rarely occurring Cabibbo-suppressed D-meson decays, for which she won APS travel award to present the work at 2007 APS meeting. Also, these measured values, of the rare decays, are most accurate till now and are being used in PDG. She has also actively monitored the raw data produced from the collisions of electrons and positrons.

Particle Physics is concerned with uncovering the basic constituents of nature and the laws governing interactions between them. Matter and anti-matter particles are collided at very high energies and the plethora of information contained in the data of these apparently chaotic collisions carries the hints about the underlying physics. Study of this sub-atomic debris has provided startling revelations about the matter that it is indeed made up of a few building blocks (quarks and leptons), up to the energy scales reached so far, interacting in a unified manner with forces which exhibit high degree of various mathematical symmetries. The unified picture of matter as emerged from these experiments is described by the theoretical frame work known as Standard Model of Particle Physics. However, the standard model has many loopholes and the time seems to be ripe for a great revolution in Particle Physics with the advent of Large Hadron Collider. Currently she is interested in understanding the disparity between matter and anti matter (CP violation), the origin of mass (search for Higgs particle) and how the current universe evolved from the big bang, what is the dark matter of the universe, by studying the proton-proton collisions at LHC. She has several publications and has also presented her work at various international conferences. She has also taught as an instructor at Syracuse University.
