She was an assistant professor at Princeton University from 1986 to 1991, and then an associate professor (1991–1997) and full professor (1997–present) at the University of Oregon. She moved to the University of Bristol in 2011 on a research professorship funded by the AXA insurance.[1][8]
Cashman studies links between chemical and physical factors that control magma ascent, eruption, and emplacement on the Earth's surface. She has studied volcanoes on all seven continents and explored a wide range of eruption styles. She is best known for her work that links the kinetics of bubble and crystal formation to the behaviour of volcanic materials, but has worked on problems that span from the chemical to physical to social aspects of volcanism. She has worked with all the US volcano observatories and served on the scientific advisory committee for the island of Montserrat.[4][9][10]
