Ursula Hamenstädt (born 15 January 1961) is a German mathematician who works as a professor at the University of Bonn.[1] Her primary research subject is differential geometry.
Education and career[edit]
Hamenstädt earned her PhD from the University of Bonn in 1986, under the supervision of Wilhelm Klingenberg. Her dissertation, Zur Theorie der Carnot-Caratheodory Metriken und ihren Anwendungen [The theory of Carnot–Caratheodory metrics and their applications], concerned the theory of sub-Riemannian manifolds.[2]
After completing her doctorate, she became a Miller Research Fellow at the University of California, Berkeley and then an assistant professor at the California Institute of Technology before returning to Bonn as a faculty member in 1990.[1]
Honors[edit]
Hamenstädt was an invited speaker at the International Congress of Mathematicians in 2010.[3] In 2012 she was elected to the German Academy of Sciences Leopoldina,[4] and in the same year she became one of the inaugural fellows of the American Mathematical Society.[5] She was the Emmy Noether Lecturer of the German Mathematical Society in 2017.[6]
