I am working to understand the basic building blocks of our universe, and the forces that cause them to interact and create the complex structures that we see as atoms, molecules, and more macroscopic objects. In the past several decades, the Standard Model of the electroweak and strong forces has become the theory that appears to successfully describe the matter around us, and provides an excellent description of the electromagnetic, weak and strong forces. My research focuses on experimental tests of this model by studying particle interactions at very high energies.
My work today is focused on measurements at the Large Hadron Collider, where we are able to collide particles together at the highest energies possible. I am a member of the ATLAS collaboration, an intimate and collegial group of 3,000 of my closest colleagues. Together, we have built and operated the ATLAS detector, using it to record the 13 TeV proton-proton collisions created by the LHC. My work from 1986 to about 2008 was focused on similar sorts of collisions created by the Fermilab Tevatron Collider, but at a lower energy of 2 TeV and recorded by the CDF detector.
My specific interest has been the top quark, the most massive particle in the Standard Model. My group was involved in its discovery, and has participated in many of the first measurements of its properties. We are now using the top quark as a tool to search for evidence of new, very massive particles that preferentially decay to top quark pairs. This work is currently using ATLAS data.
The Standard Model has many "holes" in it -- it doesn't tell us what Dark Matter is, it doesn't help us understand gravity, it doesn't tell us why there are so many different types of quarks and leptons, and it doesn't tell us why we appear to live in a matter-dominated universe. I'd like to fill in answers to some of these fundamental questions, and hope to do so using data we will collect with ATLAS over the next several years.
Detector R & DMy hardware interests have been data acqusition technologies for hadron collider detectors, digital front-end electronics systems, and off-line software development. Much of this work is performed in close collaboration with groups in Canada and the US with similar interests.
I have been also been involved in the development of pixel detectors for the ATLAS detector, the development of a precision positioning system for tracker detectors and the construction and calibration of calorimeters, which measure the energy of the particles produced in the collisions we record.
Statistical Techniques in Particle PhysicsI have been involved in the development and use of advanced statistical techniques in particle physics, with particular emphasis on multivariate analyses and setting confidence intervals.
I wrote a report describing the statistical techniques used to make the most precise estimate of the top quark production cross section. I have also written a review article on the use of "significance" in particle physics analyses.
My earlier work involved the development of the SLAC/LBL Partial Wave Analysis system (see my thesis for more details!) and the first searches for the top quark on this side of the Atlantic.

The following is a selection of recent talks I have given:
Most of my peer-reviewed publications are multi-authored papers where I have had secondary or tertiary roles. The following are a subset of the more recent papers that I have been a primary author, typically in collaboration with one of my students or postdoctoral fellows:
