Ulrike Tillmann

Professor Ulrike Tillmann FRS


Elected: 2008


Ulrike Tillmann is a mathematician who has worked in topology, K-theory, and non-commutative geometry. Her work on the moduli spaces of Riemann surfaces and manifolds of higher dimensions has been motivated by problems in quantum physics and string theory. Some of her recent work in applied topology has been motivated by the challenges in data science.


Born in Germany, Tillmann attended her local grammar school. With the help of a Wien Scholarship she studied at Brandeis University and later received her PhD from Stanford University.


Tillmann was awarded the Whitehead Prize by the London Mathematical Society (LMS) in 2004, a Bessel–Humboldt Forschungs Preis in 2008,  was elected an inaugural Fellow of the American Mathematical Society in 2012 and a Member of the Leopoldina in 2017. She has been a Fellow of the Alan Turing Institute since its establishment in 2015 and serves on scientific boards of several international  institutions, including  the Austrian Science Foundation (FWF). Currently she is the Director of the Isaac Newton Institute, Cambridge, and the President of the LMS.

A former member of  Council of the Royal Society where she also served as (interim) Vice-President in 2018, she has chaired the Royal Society's Education Committee since 2020.
