Rate My Professor Malcolm Sambridge

Professor Malcolm Sambridge is Professor of Seismology and Mathematical Geophysics in the Research School of Earth Sciences at the Australian National University. He obtained his BSc (Hons) from Loughborough University of Technology in 1983, a Certificate for Advanced Study in Mathematics from the University of Cambridge in 1984, and a PhD from the Australian National University in 1988. His career trajectory includes serving as Harry Oscar Wood Fellow at the Department of Terrestrial Magnetism, Carnegie Institution of Washington from 1988 to 1989, Research Associate at the Institute of Theoretical Geophysics, University of Cambridge from 1989 to 1992, Research Fellow at RSES ANU from 1992 to 1995, Fellow from 1995 to 2001, Senior Fellow from 2001 to 2007, Head of Seismology and Mathematical Geophysics from 2006 to 2018, Visiting Professor of Geophysics at the California Institute of Technology in 2007, and Professor since 2008.

Sambridge's research specializations encompass data inference methods, inverse theory, computational seismology, wave propagation modelling, earthquake studies, Earth structure imaging, and mathematical geophysics. He has developed innovative stochastic inverse methods, notably the Neighbourhood Algorithm, detailed in landmark publications including 'Geophysical inversion with a neighbourhood algorithm—I' (Geophysical Journal International, 1999) and its sequel '—II. Appraising the ensemble' (1999), alongside 'Geophysical parametrization and interpolation of irregular data using natural neighbours' (Geophysical Journal International, 1995) and 'Modelling landscape evolution on geological time scales: a new method based on irregular spatial discretization' (Basin Research, 1997). These works have transformed approaches to analysing seismic waves for Earth's interior structure, landscape evolution, mineral age populations from isotopic data, and infrared absorption spectra in minerals. His influence extends to uncertainty quantification using Markov chain Monte Carlo and optimal transport in geophysical inversion. Sambridge has received the Beno Gutenberg Medal from the European Geosciences Union in 2021, Fellowship of the Australian Academy of Science in 2015, Fellowship of the American Geophysical Union, and the Price Medal from the Royal Astronomical Society. He serves as Principal Investigator for the Australian Passive Seismic Server and the Australian Seismometers in Schools Network (AuSIS), with an h-index of 57 reflecting his profound impact on the field.
