Patrick Bruskiewich,
September 04-present, Patrick did his MSc thesis here at UBC in particle theory.
He has 15 years experience in industry as well as teaching, and has returned to
UBC for his PhD. Topic on Babar TBA.
Douglas Thiessen,
PhD Thesis,
September 97-February 03, "Measurement of the Branching Fraction of the Semileptonic
Decay B0-> D* l nu in the BaBar Experiment".
Doug did his MSc thesis at HERMES with SFU, and has been working on his PhD on BaBar
since fall 97. He worked on the online controls and its database system for BaBar and
quickly became a Java and object oriented coding expert. His thesis topic was
measurement of the semileptonic B meson branching ratio, which gives information on a
fundamental parameter in heavy quark decay, the CKM matrix element Vcb. This analysis
relies heavily upon lepton identification software, and Douglas performed detailed studies to
understand of muon identification
efficiencies and performed systematic cross-checks of efficiency tables obtained from
control samples other than his own.
He is now a Research Associate with the Cancer Imagining group at the BC Cancer Research
Center in Vancouver working on instrumentation to non-invasively aid in the diagnosis of skin
cancer. Past President of UBC Toastmasters. Won an APS best student presentation prize
for his thesis work presentation at the APS Northwest Section meeting in Eugene, Oregon.
Jiansen Lu ,
PhD Thesis,
September 97-December 01, "Measurement of |Vub| using B Hadron Semileptonic Decay".
Jiansen completed his MSc studies at SAL at U Saskatchewan. He started
working on his PhD on OPAL in fall 97. Jiansen worked on the online reconstruction system and
his PhD thesis topic, Vub, a parameter describing the rare b quark to u quark decays.
Jiansen devised a new method making use of neural networks to
measure V_ub using the inclusive semileptonic B decay spectrum and
inclusive discriminators in the hadronic recoil system. He was a
Research Associate on the HERMES experiment with the TRIUMF group, and is now a Research
Associate at University of Alberta, working on ATLAS (Higgs physics strategies and radiation
hard electronics).
Zhongzhi Song
MSc Thesis,
September 03- July 05. "Monte Carlo Studies for Parameterization of B-Mixing with Dilepton
Events". Feasibility study for a global fit technique to simultaneously extract B mixing and
lifetimes using dilepton events. (Applying this methodology to data, instead of Monte Carlo,
is a PhD thesis waiting to happen.) Now a PhD candidate in Economics/Finance at UBC.
Zerah Lurie
MSc Thesis,
September 99- February 02. " Evaluation of the Photonic Conversion Finder for the BaBar
Experiment". Study of converted photon backgrounds to semileptonic B decays at BaBar. This
background must be addressed in investigations of B lifetime measurements, measurements of
matrix elements and form factors in B decays, neutral B meson mixing measurements, and
measurements of charge-parity violation in B decays. As an aspiring science writer, he also
completed journalism degree here at UBC, received a prestigious science journalism internship
with Newsday in New York and is currently working with the Canadian Broadcasting Corporation
(science journalist).
Won an APS best student presentation prize for his
thesis work presentation at the APS Northwest Section meeting in Seattle.
Stephen Sewerynek, MSc Thesis ,
September 97 - April 99, "A Monte Carlo Study of the Momentum Dependence on the Results
of Tracking Unknown Particle Species in the BaBar Detector".
After a year of work at Ontario Hydro, Steve decided to come back into
physics for a MSc on BaBar, which he started in 97. His thesis is a study
which has enabled reduction in reconstruction computational time for BaBar
charged particle tracking. He examined dependencies of tracking particles
as individual species as a function of momentum and devised an algorithm
which is presently implemented in the standard Babar reconstruction code.
He worked as a satellite imaging engineer/scientist
at MacDonald Dettwiler, in Richmond BC for 1.5 years, then software guru at AvantGo in San
Mateo California, and most recently at Good Technology (also in Silicon Valley)
Cherie Goodenough,
MSc Thesis , September 94-September 96, "Background Studies for BaBar".
Fall 96, joined OPAL Technologies (they make scanning electron microscopes
for use in lithography and semiconductor industry) as a Process Engineer,
in Santa Clara, California. In 1997 OPAL Technologies was bought
out by mega-giant Applied Materials
(one of the big semiconductor companies in Silicon Valley). In 1998, she was made an offer
she couldn't refuse at Cypress Semiconductor, a silicon chip processor and manufacturer, as an
engineering physicist. In 2000, she and her family moved to Los Alamos, New Mexico, where she
worked as an engineer for a startup alternative energy sources company, Energy Related
Devices, then as a research engineer at Los Alamos National Laboratory. Now doing graduate
research in non-proliferation studies.
Jaret Heise ,
MSc
Thesis ,
September 93-March 96, "Studies of Helium-Based
Gas Mixtures Using a Small Cell Drift Chamber".
Jaret performed gas studies with the BFactory Prototype I drift chamber. These were
crucial in choosing the gas mixture we eventually used in the BaBar drift chamber. He's
completed his PhD with the
Sudbury Neutrino Observatory (SNO) experiment at UBC, specializing in Supernovae
detection and is presently an NSERC PDF at Los Alamos National Lab,
continuing with SNO.
Fan Liu, MSc Thesis, January 92 - April 94, " Measuring B0 Fragmentation Through the
Decay B0 --> D*+ lepton neutrino using the OPAL Detector at CERN".
Now working as a Computer Analyst at Bay Networks, (networking and
telecommunications) in California. Bay Networks were recently bought out
by Nortel, (new name NortelNetworks)
so Fan's getting closer to coming back to Canada!
