Biography:

Prior to joining the Light Standards group at MSL in September 2016, Joe spent the previous 15 years performing precision measurements with atomic beams, plasmas and quantum-degenerate gases and building microscopes that were used for super-resolution microscopy.

He received his PhD in physics in 2009 from York University, Toronto where he performed high-precision spectroscopy with helium atoms as a stringent test of quantum electrodynamic theory and to determine the value of the fine-structure constant. After his PhD he moved to Geneva as a postdoctoral fellow where he worked at CERN to produce and trap antihydrogen atoms in order to probe the symmetries between matter and antimatter.

In 2010 he went to Amsterdam as a postdoctoral fellow to perform high-precision spectroscopy with ultracold helium-4 and helium-3 atoms. Comparison between theory and the spectroscopic measurement allowed for determining the nuclear size of helium to within 4 attometers. Additionally, he conducted experiments that controlled the interaction strength between helium atoms confined in an optical trap by exposing the atoms to magnetic fields (known as a Feshbach resonance).

He joined a biophysics research group in Barcelona in 2013 and became the head of software development for data-analysis and image-processing algorithms for single molecule localization microscopy (STORM/PALM). He also designed and built the optical systems of the microscopes that allowed for multi-colour, live-cell imaging of biological samples.
