Early life and education
Kastner was born in Bratislava, then part of Czechoslovakia. She gained her M.Sc. in Geology from the Hebrew University of Jerusalem in 1964 followed by a Ph.D.from Harvard University in 1970.
In 1972, while a postdoctoral fellow at the University of Chicago, Kastner was approached by Scripps and asked to apply for an upcoming position as an Assistant Professor; she has been at Scripps ever since.
Kastner's research expertise is in marine geochemistry; early research focused on the origin of authigenic feldspars and of zeolites in oceanic sediments, the diagenetic transformations of opal-A and the control of dolomite formation. She also did important work on strontium distribution and on phosphate deposits. Her interests include fluid transport in the oceanic lithosphere, marine gas hydrates at convergent margins, chemical paleoceanography and the mineralogy and genesis of hydrothermal marine deposits.
