Students have a critical role and often find themselves at
the center of the most important collaboration activities. A large collaborative
experiment is a collection of hundreds of smaller experiments, with a common
physics goal and central organization. Those small experiments need to be done
by a few people, and are not too different from experiments done in smaller
in-house facilities. Students concerned about this should read through the past
graduate student thesis topics listed at the end
of this section.
I am currently working on the direct detection of Dark Matter with the PICO
collaboration. So far, I have been involved and taken a lead in various tasks
related to hardware design/assembly, experimental operations and data analysis
in the PICO experiment that is deployed in SNOLAB underground laboratory. Prior
to this, I did my masters at York University and worked in CERN on the ALPHA
experiment (anti-hydrogen production/trapping) to study fundamental symmetries
between matter and antimatter.
I'm a master student currently working on SNO+
experiment. My work right now is mainly concerned with 'finishing' fabrication
of umbilicals (remember to thank me for doing this when you came here...) &
'starting' data flow. I'm also responsible for developing sodium source for
liquid scintillator phase.
I am a student working with SuperCDMS,
my work so far has consisted of assessing a two-template fitting model for
phonon pulses that come out of the detector. I have also done research at CERN,
and in modelling relativistic supernova shock propagation.

I am a PhD student, currently working on Dark Matter detection with NEWS. My
contribution so far has been on the analysis of data from the previous version
of the experiment in the Laboratoire Souterrain de Modane. My focus is on
understanding the pulse shape of our events, so that we might extract their
intrinsic structure and characterize them better.
I work on the SNO+ experiment,
and I am currently working on scintillator purification and radon background
I am a master student currently working in
SuperCDMS. The main aim of the
experiment is to measure the recoil energy out of the nucleus due to collision
with Weakly Interacting Massive Particles (WIMPs) using highly sensitive
I'm a master's student working on the
DEAP experiment. My current research is
essentially trying to understand the signal contributions from contaminants in
the detector using computer simulations. More specifically, I am working on
trying to understand the contamination profile based on comparing simulation and
real data, and developing ways to exclude contaminant decays events from dark
matter interaction events.
I'm a PhD candidate working on the DEAP-3600 experiment, which is currently
taking data in hope to find evidence for the existence of dark matter. My
involvement with DEAP-3600 ranges between various activity from R&D and
construction to different data analysis tasks. My primary focus is the
identification and reduction of alpha decays from the Uranium and Thorium
chains. Those type of decays could, in specific conditions, produce a signal
similar to what expected from dark matter. Prior to this, I did my masters at
Royal Holloway University of London where I was involved with another dark
matter experiment called DMTPC.
I am a Masters student working with the SNO+ Collaboration. I am currently
involved in scintillator purification and nitrogen source calibration for the
water phase of SNO+. I did my undergraduate studies in Mathematical Physics at
the University of Waterloo.
As a Ph.D. student, I share my time in three parts: research, teaching and
taking courses. Currently I am working on simulations for the NEWS-SNO project,
to determine the expected background from the different sources of
contamination. These backgrounds come from the detector itself or from the
experimental area (rock, air, etc.). We can reduce them by using clean
materials and building shields around the detector. Reducing is not eliminating,
so simulations can give us an estimation of the number of events which will come
from contamination, and help us to differentiate background from real
I am a Master's student working on the NEWS dark matter detection experiment.
My work so far has consisted of working on the production of Argon-37 as a
calibration source, and analyzing charge-sensitive amplifier noise. Prior to
this, I did my undergraduate degree at the University of Alberta, including work
on the PICO and SNO+ experiments.
