Yin Hsien Fung

Senior Research Scientist

Mass and Pressure

Areas of expertise

• Mass and length, and related quantities: density, pressure and volume
• Kibble balance development
• Experimental atomic, molecular and optical physics


  • PhD (Otago), Atomic, Molecular and Optical Physics, 2017


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.
