Balances and Weighing Workshop

Fung joined MSL in August 2016 as a research scientist and is now one of our lead scientists in the Mass Quantities team. 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 also leads the MSL team in constructing the MSL Kibble balance with focus on the displacement measurements using interferometry and characterization of the pressure balances.

Fung has published a number of research papers and is very active in STEM outreach activities. Fung recently won the Early Career Researcher Award at the 2020 Science NZ awards.

Prior to joining MSL, Fung was pursuing his doctoral studies at the atomic physics lab in University of Otago, which is part of 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 strong interest in science communication and had been regularly organizing science educational outreach programmes for rural schools in Otago/Southland region.

Greg has worked as a mass and density metrologist at the Measurement Standards laboratory since 2005. His work includes calibration of hydrometers, density standards, volumetric glassware, and weights and balances from the high-accuracy state-of-the-art level (about 1 in 100 million) to those used in trade and industry, which require an accuracy of 0.1 %. His current research interests include the automation of mass comparisons.

Rebecca grew up in Wellington, and completed a BSc in Maths and Physics at Victoria University of Wellington followed by Honours and Masters in Physics. For her Masters project, she made blue-emitting OLEDs and studied their degradation during operation using electrically- and optically-detected electron paramagnetic resonance. Rebecca then moved to Oxford to investigate the lead-halide perovskites, a new class of materials which show great potential for use in solar panels. Her PhD project involved fabricating and characterising thin-films of inorganic lead-halide perovskites and testing them as the light-absorbing material in photovoltaic devices. Following her PhD, Rebecca used molecular dynamics simulations to investigate how the motion of droplets may be controlled with switchable surfaces. Rebecca has also been involved in developing and running science outreach workshops for both primary and high-school students.
