Anna Ruth Halberstadt is an assistant professor at University of Texas at Austin, in the Earth and Planetary Sciences department. Her research integrates geologic data and numerical models to reconstruct climate and ice sheet dynamics across many different time periods, focusing on warm climates in the geologic past as well as the future. Dr. Halberstadt received B.S. and M.S. degrees from Rice University, followed by a Ph.D. from University of Massachusetts – Amherst. She completed a postdoctoral fellowship at Berkeley Geochronology Center prior to moving to Austin TX and beginning her professorship at UT. Dr. Halberstadt has conducted field work in Antarctica, aboard research vessels (a US-funded expedition in 2015, and an international scientific drilling ship in 2019) as well as on land (an ‘on-ice’ collaboration with New Zealand colleagues to collect data in the McMurdo Dry Valleys in 2016).
