Matthew B Day

Matthew B. Day is an Associate Professor in the Department of Mathematical Sciences at the University of Arkansas, Fayetteville. He holds a Ph.D. in Mathematics from the University of Chicago (2008) and previously held postdoctoral positions at Caltech. His research focuses on geometric group theory, low-dimensional topology, and combinatorial group theory, with a recent emphasis on automorphism groups of right-angled Artin groups. He has received multiple NSF grants and fellowships, including a Postdoctoral Research Fellowship (2008–2010) and a Graduate Research Fellowship (2002–2007). He has co-organized conferences like the Redbud Topology Conference and contributed to teaching graduate and undergraduate courses in topology, algebra, and analysis.

• Education: B.S. Mathematics, B.A. Linguistics & Philosophy (UT Austin, 2002); M.S. and Ph.D. in Mathematics (University of Chicago, 2004 and 2008).
• Professional Service: Organized the 2015 Arkansas Spring Lecture Series, reviewed for Mathematical Reviews, and served on university committees for hiring and curriculum.
• Research Trends: His work bridges geometric group theory with low-dimensional topology, exploring automorphism groups, mapping class groups, and symplectic structures. Recent papers address cohomological dimensions, subspace arrangements, and finiteness properties of groups.

He has advised conferences and collaborates with institutions like the Ohio State University and Trinity College, Dublin. His teaching spans foundational courses to specialized graduate topics in topology and algebra.
