Brian Schmidt

Research and career

Schmidt was a postdoctoral research Fellow at the Center for Astrophysics | Harvard & Smithsonian (1993–1994) before moving on to the ANU's Mount Stromlo Observatory in 1995.

In 1994, Schmidt and Nicholas B. Suntzeff formed the High-Z Supernova Search Team to measure the expected deceleration of the universe and the deceleration parameter (q0) using distances to Type Ia supernovae. In 1995, the HZT at a meeting at the Center for Astrophysics | Harvard & Smithsonian elected Schmidt as the overall leader of the HZT. Schmidt led the team from Australia and in 1998 in the HZT paper with first author Adam Riess the first evidence was presented that the universe's expansion rate is not decelerating; it is accelerating. The team's observations were contrary to the then-current models, which predicted that the expansion of the universe should be slowing down, and when the preliminary results emerged Schmidt assumed it was an error and he spent the next six weeks trying to find the mistake. But there was no mistake: contrary to expectations, by monitoring the brightness and measuring the redshift of the supernovae, they discovered that these billion-year old exploding stars and their galaxies were accelerating away from our reference frame. This result was also found nearly simultaneously by the Supernova Cosmology Project, led by Saul Perlmutter. The corroborating evidence between the two competing studies led to the acceptance of the accelerating universe theory and initiated new research to understand the nature of the universe, such as the existence of dark energy. The discovery of the accelerating universe was named 'Breakthrough of the Year' by Science in 1998, and Schmidt was jointly awarded the 2011 Nobel Prize in Physics along with Riess and Perlmutter for their groundbreaking work.

Schmidt is currently leading the SkyMapper telescope Project and the associated Southern Sky Survey, which will encompass billions of individual objects, enabling the team to pick out the most unusual objects. In 2014 they announced the discovery of the first star which did not contain any iron, indicating that it is a very primitive star, probably formed during the first rush of star formation following the Big Bang.

He is the chairman of the board of directors of Astronomy Australia Limited, and he serves on the management committee of the ARC Centre of Excellence for All-Sky Astrophysics (CAASTRO). In July 2012 Schmidt was given a three-year appointment to sit on the Questacon Advisory Council. As of March 2017, Schmidt serves as a member of the Bulletin of the Atomic Scientists' Board of Sponsors.

ANU Vice-Chancellor

On 24 June 2015 it was announced Schmidt would replace Ian Young as the 12th Vice-Chancellor of the Australian National University, to commence his tenure on 1 January 2016. The Chancellor of the ANU, Professor Gareth Evans, said, "Brian Schmidt is superbly placed to deliver on the ambition of ANU founders – to permanently secure our position among the great universities of the world, and as a crucial contributor to the nation ... We had a stellar field of international and Australian candidates, and have chosen an inspirational leader. ... Brian's vision, vitality, global stature and communication skills are going to take our national university to places it has never been before." On 2 February 2023, Schmidt announced that he would be stepping down as vice chancellor at the end of the year.

Science advocacy

The publicity that came with winning the Nobel Prize has given Schmidt the opportunity to help the public understand why science is important to society, and to champion associated causes.

Public education

One of his first acts after winning the Nobel Prize was to donate $100,000 out of his prize money to the PrimaryConnections program, an initiative of the Australian Academy of Science that assists primary school teachers. He has continued to press for improvements to the public school system, particularly in the sciences and mathematical literacy (numeracy). He sees the major problem is that so few of the teachers are trained in "STEM" (science, technology, engineering and mathematics) disciplines. He used the opportunity of delivering a speech at the National Press Club to call for more focus on the public education system, including holding principals more accountable and the proper use of standardised testing, concluding with the warning that otherwise "the fundamental tenet of Australian democracy, that we all deserve a fair go, is at risk of being eroded away along with our public school system." At the other end of the spectrum, he also raises the profile of the matter by visiting primary schools personally to answer children's questions.

Funding for scientific and medical research

Schmidt is a strong supporter of funding scientific and medical research on a long-term, non-partisan basis driven by a national research strategy. He has often voiced his concern that the current year-to-year uncertainty and lack of co-ordination make it difficult to establish and staff large facilities, or to participate in multi-national ventures, and that scientists spend too much time applying for funding instead of doing research. Interviewed by the Australian Financial Review, Schmidt was characteristically forthright: "It's unclear to me whether or not we will continue to be a great astronomy nation... If we're damaged it will take 20 years to fix ourselves. It only takes one year to cause 20 years of damage."

Climate change

He urges people to pay attention to the consensus of expert opinions, instead of basing their conclusions on the incomplete information which they personally know. Launching the Australian Academy of Science's report "The science of climate change: questions and answers", Schmidt commented that "Whenever this subject comes up, it never ceases to amaze me how each person I meet suddenly becomes an expert... More surprising is the supreme confidence that non-experts (scientists and non-scientists alike) have in their own understanding of the subject." In 2014 he put up $10,000 of his own money in a bet with Maurice Newman, chairman of the Prime Minister's Business Advisory Council from 2013 to 2015, that global temperatures will rise. In 2015, he presented the Mainau Declaration 2015 on Climate Change on the final day of the 65th Lindau Nobel Laureate Meeting, which was signed by 76 Nobel Laureates and handed to then President of the French Republic, François Hollande, as part of the successful COP21 climate summit in Paris.

Personal life

Schmidt is married to Jennifer Gordon. They met while they were both studying for their PhDs at Harvard – he in astrophysics and she in economics. They decided to settle in Australia, which he had already visited on several occasions to visit family. He now holds dual citizenship of Australia and the United States.

He is not religious, being described as a "militant agnostic" with his tagline, "I don't know, and neither do you!"

Vineyard and winery

Schmidt and his wife own and operate Maipenrai Vineyard and Winery, a small winery established in 2000 in Sutton, near Canberra. The vineyard covers 1.1 hectares (2.7 acres), producing exclusively pinot noir grapes, and the wines have received favourable reviews. Schmidt has quipped that "it's easier to sell your wine when you have a Nobel prize". At the 2011 Nobel Prize Ceremonies in Stockholm, he presented the King Carl XVI Gustaf of Sweden with a bottle of wine from his winery.

In 2013, Schmidt was appointed to join the board of the federal government's Australian Wine Research Institute. The Institute's chairman Peter Dawson commented that Schmidt brings to the board "a unique combination of scientific excellence, wine industry knowledge and relevant board experience".
