Dave Morris

Dave Morris is a Professor in the Department of Mathematics & Computer Science at the University of Lethbridge since 2003. He holds a PhD in Mathematics from the University of Chicago (1985). His research focuses on algebraic and geometric aspects of group theory, particularly infinite matrix groups, arithmetic groups, and applications to graph theory and dynamical systems.

Key research areas include:

• Arithmetic groups and their rigidity properties
• Algebraic properties of infinite matrix groups
• Applications of finite groups in graph theory (e.g., Cayley graphs)
• Unipotent flows and Ratner's Theorems

His publications span over 50 works, including books on Ratner's Theorems (2005), Ergodic Theory (2008), and an open-access textbook on abstract mathematics (with Joy Morris). He has delivered numerous talks on topics like Hamiltonian cycles in Cayley graphs and actions of Lie groups on manifolds.
