Uwe Grimm
Uwe Grimm (March 9, 1963 in Gütersloh, Germany – October 28, 2021 in Oxford, United Kingdom) was a German mathematician and physicist. He was one of the pioneers in aperiodic tilings and their dynamical and spectral properties. He also worked in statistical physics and combinatorics. Uwe Grimm earned his Ph.D. from the University of Bonn in 1991 with a thesis in statistical mechanics on quantum spin chains and their symmetries, written under the supervision of Vladimir Rittenberg. After that he spent eight years as a postdoctoral researcher in Melbourne, Amsterdam and Chemnitz, where he completed his habilitation on the  physics of aperiodic order. In 2000 he joined the Open University in Milton Keynes, where he became a professor in 2009. He was Head of the Department of Mathematics and Statistics from 2014-2016. He served as Co-editor of Acta Crystallographica Section A and was Chair of the IUCr Commission on Aperiodic Crystals from 2014-2017.
