Sir Alexander Norman Halliday is the Director of the Earth Institute at Columbia University.[1] He joined the Earth Institute in April 2018, after spending more than a decade at the University of Oxford, during which time he was dean of science and engineering. He is also a Professor of Earth and Environmental Sciences[2] at Columbia University.

Early lifeEdit

Halliday comes from Penzance, Cornwall, in the UK.[3] He went to school at the Humphry Davy Grammar School where he studied geology. He received his graduate degree and Ph.D. in geology from the University of Newcastle upon Tyne, in 1977.


Professor Alex Halliday FRS was Professor of Geochemistry at the University of Oxford from 2004-2018. Before coming to Oxford, he spent twelve years as a professor at the University of Michigan and then six years in Switzerland, where he was Head of the Department of Earth Sciences at the ETH in Zurich. His research involves the use of isotopic methods to study Earth and planetary processes.

Halliday is a former President of the Geochemical Society;[4] the European Association of Geochemistry; and the Volcanology, Geochemistry and Petrology Section of the American Geophysical Union. He has experience with a range of top science boards and advisory panels including those of the National Environment Research Council, HEFCE, the Natural History Museum London, the Max Planck Society, the Royal Society and the American Geophysical Union. At Oxford he was Head of the Division of Mathematical, Physical and Life Sciences (science and engineering) from 2007 to 2015. In 2014, he was elected Vice-President and Physical Secretary of the UK's Royal Society.[5] He is currently a Fellow of the Royal Society[6] and Foreign Associate of the US National Academy of Sciences.

On 14 December 2017 it was announced that Professor Halliday will be appointed as the new Director of Columbia University's Earth Institute. As a professor in Columbia’s Department of Earth and Environmental Sciences, Halliday divides his time between Columbia’s Morningside campus and his geochemistry lab at Lamont-Doherty Earth Observatory.


Alex Halliday is an isotope geochemist known for novel mass spectrometry[7] techniques and their applications to the Earth and planetary sciences. An enthusiast for technological innovation, most of Halliday's recent research is in developing and using new mass spectrometry techniques to shed light on the origin and early development of the solar system[8] and recent Earth processes, such as continental erosion and climate. However, he has also been engaged in other studies, such as the mechanisms of volcanic eruptions, and the formation of mineral and hydrocarbon deposits. Halliday has over 400 published research papers.[9]

Accomplishments and awardsEdit

Halliday's scientific accomplishments have been recognised with awards including the Murchison Medal of the Geological Society,[10] the Bowen Award and Hess Medal[11] of the American Geophysical Union,[12] the Urey Medal of the European Association of Geochemistry[13] and the Oxburgh Medal of the Institute of Measurement and Control.[14] He was elected a Fellow of the Royal Society in 2000 and a Foreign Associate of the U.S. National Academy of Sciences in 2015.[15] He was appointed a Knight Bachelor in the 2019 New Year Honours for services to Science and Innovation.
