Dr Waszek is a global seismologist, researching the seismic properties of Earth’s deep interior from the inner core to the upper mantle. She is particularly interested in the relationship between seismic structures and their geodynamical origin. She is currently investigating the properties and characteristics of mantle transition zone and mid-mantle discontinuities, and their relationship to mantle convection and composition.
