Greg A. Valentine

Greg A. Valentine is a UB Distinguished Professor in the Department of Earth Sciences at the University of Buffalo, State University of New York. He specializes in basaltic volcanism, pyroclastic deposits, and volcanic risk assessment through multiphase fluid dynamics and numerical modeling.

• Education: PhD in Geological Sciences, University of California Santa Barbara (1988)

His research encompasses physical processes of basaltic eruptions, from small-scale vent dynamics to large-volume ignimbrite-forming events. Key areas include computational fluid dynamics for pyroclastic currents, soft sediment deformation in dry pyroclastic deposits, and volcanic landform evolution in arid environments.

Recent publications (2024-2018) reveal trends in

• phreatomagmatic explosion dynamics,
• numerical modeling of pyroclastic flows,
• erosion processes in volcanic constructs,
• caldera-forming eruptions,
• lithic content in ignimbrites,
• magma-water interaction experiments.

Scientific Awards:

• UB Distinguished Professor

He has advised 9 PhD and MS students, including Brandon Keim (2022) on computational models of pyroclastic surges and Maria Clara Parreira Murta (2022) on Utah basaltic volcanism. Former students like Andrew Harp (2018) and Matthew Sweeney (2018) explored magma transport and multiphase eruption modeling respectively.
