Academic Career and Research Areas

Elisabeth Ullmann (b. 1979) conducts research in the area of uncertainty quantification using tools from numerical analysis, applied probability theory and computational science and engineering. Her work focuses on efficient discretizations, iterative solvers and estimators for partial differential equations with random coefficients.
Ullmann studied applied mathematics at TU Bergakademie Freiberg. She obtained her doctorate in Freiberg and subsequently worked as a postdoctoral researcher on DFG priority program “Extraction of quantifiable information from complex systems”. In 2009 she was a visiting research associate at the University of Maryland, College Park. From 2011 to 2014 she was a research associate at the University of Bath in England and subsequently at the University of Hamburg. In 2015 she joined TUM as an assistant professor.
