Research - I'm currently pursuing a Phd in experimental particle physics under the supervision of Dr. Thomas Mattison. My research is based on data and simulations of the BaBar Experiment at SLAC (
http://www.slac.stanford.edu/BFROOT).

PhD Thesis Abstract: My PhD project will be an analysis of neutral B-meson mixing and lifetimes using dilepton events. I will post more detailed information here soon, but here is my PhD thesis proposal. PhD Thesis Proposal.

Master's Thesis Abstract: This thesis contains a study of track-impact parameter resolution in the BABAR detector using lepton pair events from e+e- -> l+l-(gamma) and from gamma*gamma* -> l+l- where l is either mu or e. The high number of these events in the data set and Monte Carlo simulations allows the tails of the resolution to be studied in detail. The Gaussian core of the resolution is consistent within 20% with the track-by-track errors returned by the track fitting software for both data and Monte-Carlo simulations. Beyond about three standard deviations (sigma) the non-Gaussian tail approximately obeys power laws. A simple parameterization is presented which fits the data well to beyond 10 sigma. The tail shape is consistent with that expected from a large-angle Coulomb scattering Toy Monte-Carlo. The GEANT 4 -based BABAR Monte Carlo software reproduces the core out to approximately 2 sigma but the behaviour of the tails further out disagrees with the data and the predictions of Moliere Theory.

UBC Thesis LaTeX Class: Are you a UBC Grad student yourself? Need a LaTeX template to create your thesis? Michael Forbes created a nice one, and I used it for my Master's thesis above. You can download it here. UBC Thesis Class.

As an undergraduate, I spent one year working on the data-acquisition system of the TRINAT experiment at TRIUMF. (http://www.triumf.ca/welcome/trinat_exp.html)

Teaching - I worked as a Teaching Assistant (TA) in the following lab courses:

As a UBC Teaching Assistant (TA), I'm a member of the CUPE Union Local 2278. ( http://www.cupe2278.ca)

Quantum Mechanics - Finally, I have put a lot of time and energy into my grad courses, especially Quantum Mechanics & Quantum Field Theory. Here are some useful links I came across during late-night homework sessions. You might find them useful in your grad-level QM course.
