Biography

Fung joined MSL in August 2016 as a research scientist. Since then, Fung has been undergoing training as a metrologist in mass and pressure standards. Other than maintaining and disseminating the mass standards, Fung is developing density measurement capabilities, especially in liquid density determination by using electronic densitometers and reference liquid density standards. Fung is also part of the MSL team in constructing the MSL-designed Kibble balance, with focus on the displacement measurements using interferometry and characterisation of the pressure balances.
Prior to joining MSL, Fung was pursuing his doctoral studies at the atomic physics lab in University of Otago, which is part of the Dodd Walls Centre for Photonic and Quantum Technologies. His thesis topic was on the deterministic method to prepare single atoms in the motional ground state by using lasers and optics, in which the techniques can be applied in quantum metrology. Fung has a strong interest in science communication and had been regularly organising science educational outreach programmes for rural schools in Otago/Southland region.

Professional activities
