Biography
My primary research is directed at the study of new
particles and new interactions using the ATLAS detector at the Large Hadron
Collider at CERN. My group has been
active in the commissioning of the ATLAS pixel detector, where we have
participated in the development of the data acquisition system and various
calibrations. Although we are broadly
involved in searches for new physics, we have initially been focused on the study
of jets and photons in high-energy proton-proton collisions. We are active in work pertaining to jet and
photon energy calibrations as well as first QCD measurements. As the data size increases, we will continue
to participate in the study of jets and missing energy that provide potential
signals for the study of SUSY and the search for Dark Matter, as well as
searching in the Higgs to two-photon channel.
We are also pursuing R&D activities in collaboration
with Brookhaven National Lab and Strasbourg (IPHC) on ultra-thin silicon
detectors for future colliders. Nevis laboratory has a high intensity x-ray
source, which provides a unique test facility for new detectors to be used in
high radiation environments. The
silicon research also will provide PhD theses for Columbia students based in
New York City. A significant research
investment in undergraduate education is also attached to this laboratory work.
Via my background in nuclear physics activities, I have a
deep interest in issues relevant to nuclear proliferation.
