Prof. Daniel Shaddock

Chief Executive Officer
Daniel Shaddock is also a Professor in Physics at the Australian National University. His research focuses on precision measurements using advanced digital signal processing. Prof Shaddock led Australia’s involvement in GRACE Follow-on, a satellite mission launched on May 22, 2018 to track the Earth’s water movement. Prior to this work Daniel was a Director’s Fellow at NASA’s Jet Propulsion Laboratory where he served as NASA’s Interferometer Architect for the LISA mission. He is a Fellow of the American Physical Society and his publications have been cited over 20,000 times. Daniel was a co-author on the paper announcing the observation of gravitational waves, an achievement that was awarded the 2017 Nobel Prize in Physics.

Paul Altin, Ph.D.

Chief Scientist
Paul earned his Ph.D. in experimental quantum physics at the Australian National University in 2012, before moving to Germany to take up an Alexander von Humboldt fellowship at the Max Planck Institute for quantum optics in Garching. His research has spanned a range of fields across physics and precision measurement, including ultracold quantum gases, atom interferometry, precision gravimetry, dark matter, cavity quantum electrodynamics and gravitational wave detection. Paul has co-authored over 100 journal articles and was a member of the Nobel-Prize-winning team that made the first detection of gravitational waves from a pair of colliding black holes in 2016. At Liquid Instruments, Paul is responsible for designing the instruments and user interfaces that provide scientists and engineers with industry-leading usability and features.

Tarquin Ralph, Ph.D.

VP Business Development
After studying Physics, Tarquin Ralph worked building online banking systems before becoming the Marketing Manager of an Australian bank where he completed his MBA. He then spent time at two large international Advertising Agencies as Strategy Director. In the early nineties he moved to Canberra and into Management Consulting, first as a partner in Accenture and then as Managing Partner, Federal Government for Deloitte. He focused on change management and large scale program management, delivering or quality assuring 29 large Government programs, two of which were over half a billion dollars in size. In 2007 he established his own consulting company which specialises in bringing large consulting disciplines to mid-sized government clients. This firm still operates today. As his clients started to retire, he decided to return to university to take a PhD as a part of Daniel Shaddock’s group. His particular focus was the spatial modulation of laser light using digital interferometry to optimise transmission through a cavity. He is a founder of Liquid Instruments and an early board member and continues to offer a range of business advice.
