Postdoctoral Researcher with Rare Decay group TRIUMF

Posting Expiry

Please refer to reference number PDFO-56729 when applying for this position.


The University of British Columbia’s Department of Physics and Astronomy and TRIUMF are seeking applications from recent particle physics graduates interested in a Postdoctoral position with the Rare Decay Group at TRIUMF. TRIUMF is Canada's particle accelerator centre, and one of the world's leading laboratories for particle and nuclear physics and accelerator-based science. TRIUMF is  an international centre for discovery and innovation, advancing fundamental, applied, and interdisciplinary research for science, medicine, and business.

The Rare decay group consists of ten scientists including four faculty members participating in the PIONEER, PIENU and NA62 experiments with  R&D, detector construction, analysis tool development, simulations, and physics analysis.

As the successful applicant, you will have an opportunity to participate in research related to studies of rare pion decays with the PIONEER experiment at the Paul Scherrer Institute (PSI). PIONEER ( is a next generation pion decay experiment focusing on precision tests of  flavor physics. PIONEER is building on the previous PIENU (at TRIUMF) and PEN (at PSI) experiments. PIENU results currently provide the best test of lepton universality and are sensitive to a plethora of large mass and low mass new physics. PIONEER will improve the sensitivity to new physics by one order of magnitude and will address  the unitarity of the Cabibbo–Kobayashi–Maskawa matrix through studies of pion beta decay. The PIONEER collaboration is an international team from 25 institutes from Canada, China, Europe, Japan and US.

As a member of the TRIUMF/UBC team, you will focus on and contribute in a significant manner to the development of the PIONEER experiment through:

• Simulations, detector R&D, and data analysis
• Data collection and shift-taking at PSI 
• Preparing reports and disseminating results as articles in peer-reviewed scientific journals and at national and international conferences and workshops
• Supervising undergraduate and/or graduate students

As the successful applicant, you will have expertise in  one or more  areas of data analysis and simulation techniques, software, and radiation detectors used in particles physics. Ideally this will include:
• Experience in instrument and/or electronics development particularly noble gas detectors and calorimetry, but also silicon and other detectors 
• Experience in data analysis and simulation
• Software proficiency e.g. with C++, ROOT, and Monte Carlo simulations using GEANT4, and expertise or interest in machine learning techniques
• Good interpersonal and communication skills, and the ability to work as an effective team member
• Ability and flexibility to travel  as required

Applicants must have a Ph.D. in particle physics that was awarded in the last 5 years or that will be awarded in the near future.

TRIUMF is located on the south campus of the University of British Columbia, in the heart of Pacific Spirit Park in Vancouver, BC.  We offer a competitive total compensation package, including comprehensive benefits, attractive salary, and an excellent opportunity to enhance your career portfolio in a high profile national research facility.   

TRIUMF is an equal opportunity employer, and we welcome applications from all qualified candidates.  This grant funded position is jointly offered by UBC’s Department of Physics and Astronomy and TRIUMF, located on the UBC campus.

Postdoctoral applications must:

Upload cover letter, brief statement of research interests, detailed CV with a list of publications 

Arrange for 3 letters of reference sent directly to and include JR number (JR100269) in subject line

Application closing date:    January 15, 2023

As a requirement of this position, the successful candidate will need to provide acceptable proof that they have been fully vaccinated for COVID-19, or demonstrate that they are unable to be vaccinated against COVID-19 for reasons protected under the BC Human Rights Code. TRIUMF will grant reasonable accommodation requests up to the point of undue hardship.
