I have done work for both NEWS
and DEAP. I have a Bachelor's
degree from the University of Science and Technology of China and a PhD from the
University of Minnesota--Twin Cities. I joined the group in 2006 as a fresh PhD
graduate. After a short stay in Caltech in 2009, I decided to move back to
Canada and have been with the Queen's Physics department since.
I'm a postdoctoral fellow working with Dr. Tony Noble on the
PICASSO and PICO
dark matter search experiments at Snolab. I work both on and off-site on a range
of activities including detector operation, data analysis, and the development
of a small-size test bubble chamber at Queen's University. I earned my doctoral
degree in 2012 from Bern University, Switzerland, working with Dr. Jean-Luc
Vuilleumier. My dissertation research focused on the search for neutrinoless
double beta decay of xenon-136 within the EXO collaboration. After graduating, I
continued working as a postdoctoral fellow with Dr. Vuilleumier on the
development of a novel light detection scheme for use in medium-pressure gas
TPCs. I hold a master's degree from Université de Montréal where I worked with
Dr. Viktor Zacek on the detector fabrication, installation, and data analysis of
the PICASSO experiment.
I joined the NEWS-SNO experiment at Queen's in early 2016 as a
postdoctoral fellow after I completed my PhD in Fance within the
EDELWEISS collaboration (Direct dark matter searches using HP-Ge
crystals). I've been mainly focusing on the analysis of WIMP search data
taken with a prototype for NEWS-SNO : a 60 cm diameter sphere installed
at the LSM (Underground Laboratory in France). In parallel, I split my
time between lab activities and simulations for electron drift times
I started my work at Queen's in January 2009 and I'm focused on
matter experiment. Before, during my grad studies at the Jagiellonian
University in Krakow and at the Paul Scherrer Institute, I had been
involved in slightly different physics (physics of cold and ultracold
neutrons, neutron electric dipole moment). Currently, I am working mainly
on Monte Carlo simulations of the detector and reduction of radioactive
backgrounds (using ultra pure polymer coatings), plus some unrelated R&D
and mining, occasionally.
Hi! After I completed my PhD at Virginia-Tech, I joined
SNO+ with the Queen's group to
continue research in ultra-low background neutrino physics as a post-doctoral
fellow. I am currently focusing on purification of a major component of our
liquid scintillator that will be used in the neutrinoless double beta decay
phase of SNO+. In spare time, I try
to help with detector calibrations, various small-scale hardware projects, and
software development or analysis whenever possible. Personally, my humble goal
at Queen's is to help improve precision measurement of the solar neutrino
spectrum and get a glimpse into the (hopefully dual) nature of a neutrino
I recently joined the NEWS-SNO experiment which aims to probe
the light Dark Matter sector using a new concept of spherical gaseous
detector. My main effort up to now has been two-fold. First, I have
been analyzing prototype data collected in France (LSM) to extract
limits on a possible WIMP signal. Secondly, I have been designing the
NEWS-SNO calibration system while helping with other R&D projects
to facilitate a smooth setting up of the experiment at SNOLAB.
Prior to joining NEWS-SNO, I did a short term post-doc on PICO. With this experiment I focused on background reduction using a wavelet
approach for bubble technologies I developed during my PhD program.
I joined the SuperCDMS collaboration in July 2015 as a postdoctoral fellow at
Queen's. My main focus is working with Dr. Philippe Camus to build a cryogenic
underground test facility (CUTE) at SNOLAB. It will provide the opportunity to
test the discrimination power and energy resolution of the SuperCDMS detectors
underground. This facility will also help with incorporating the EURECA detector
towers into the SuperCDMS cryostat, bringing additional payload of detectors
into the experiment. Before moving to Canada, I finished my Ph.D. studies at
University of Oxford, working with Dr. Hans Kraus on developing and producing a
radio-pure cryogenic cabling system for the EDELWEISS experiment, as well as
constructing a novel phonon-scintillation cryogenic detector module based on
scintillating crystal, NTD-Ge sensor and PMT for next-generation dark matter
direct detection and other future rare event searches.
