Tim Johnson

Professor Tim Johnson is a faculty member in the School of Earth and Planetary Sciences at Curtin University, where he has been employed since January 2014. His research focuses on metamorphic petrology, particularly the application of phase equilibria modelling using internally consistent thermodynamic data. Professor Johnson received his Honours degree in 1992 and PhD in 1999, both from the University of Derby in England.

• 1992: Honours degree, University of Derby, England

Professor Johnson's research concentrates on the study of crystalline rocks from various geographic and geodynamic settings to understand fundamental processes on Earth. His expertise lies in metamorphic petrology, particularly the application of phase equilibria modelling. Much of his work focuses on the generation, segregation and migration of melt in the crust and upper mantle, which are fundamental processes driving the evolution of the lithosphere.

His current research interests include the early Earth, planetary differentiation, secular change in metamorphism, and the consequences of giant impacts. Professor Johnson conducts extensive fieldwork, particularly in northwest Scotland, northeast Scotland, and western Norway. His publications demonstrate a progression from regional metamorphic studies toward broader questions about Earth's early evolution and planetary processes.

At Curtin University, Professor Johnson teaches undergraduate courses including GEOL3001 Tectonics and the Dynamic Earth and GEOL3011 Geology Mapping Project. He also runs online and face-to-face THERMOCALC courses and occasionally teaches short courses on crustal melting. His research group focuses on applying thermodynamic modeling to understand metamorphic processes and crustal evolution across geological time.
