Matthew B. Day

Matthew B. Day is an Associate Professor in the Department of Mathematical Sciences at the University of Arkansas. His research focuses on geometric group theory, low-dimensional topology, and combinatorial group theory, with a particular emphasis on automorphism groups of right-angled Artin groups (RAAGs), free groups, and mapping class groups.

• Research Interests: Automorphism groups, RAAGs, free groups, Torelli subgroups, Johnson homomorphisms, symplectic structures on groups.
• Collaborators: Richard D. Wade, Andrew Putman, Benson Farb (PhD supervisor).
• Education: PhD from the University of Chicago (2008), supervised by Benson Farb.
• Key Contributions: Studied virtual cohomological dimensions, solvable subgroups, and exact sequences related to automorphism groups.
