Moritz Reintjes received a Ph.D. from the University of California in Davis, a Master degree (Diplom) from the University of Regensburg in Germany (where he grew up) and a B.Sc. (Honours) from the University of Cape Town. He held post-doctoral positions at the University of Regensburg (2011-2012), the Max Planck Institute for Gravitational Physics (2012), the University of Michigan - Ann Arbor (2013), the Instituto de Matematica Pura e Aplicada in Rio de Janeiro (2013-2016), the Instituto Superior Tecnico in Lisbon (2017 - 2018) and the University of Konstanz (2019 - 2021). He joined the City University of Hong Kong as an Assistant Professor in 2021.

He is interested in Mathematics that models phenomena of nature. His research concerns Mathematical Physics, using and developing the theory of Partial Differential Equations and Geometry. In particular, he worked for several years on the problem whether spacetime singularities of shock waves in General Relativity are removable. In collaboration with Blake Temple (UC Davis), he recently resolved this problem in the affirmative, and their method of proof extends Uhlenbeck compactness to Lorentzian geometry and to Yang-Mills connections with compact and non-compact gauge groups.
