I am a PhD physics student working on the TRIUMF Weak Interaction Symmetry Test (TWIST).
We are looking for physics beyond the Standard Model by precisely measuring the positron spectrum from muon decay.
The work takes place at the TRIUMF laboratory in Vancouver, Canada.
Prior to this I completed my undergraduate studies at the University of Oxford.
