Thomas Gilsdorf

Thomas Gilsdorf is a Professor of Mathematics at Central Michigan University's Department of Mathematics. His research spans two primary areas: topological vector spaces and cultural mathematics (ethnomathematics). He holds a Ph.D. in Mathematics from Washington State University (1988), an M.S. in Mathematics with Computer Science from Mankato State University (1984), and a B.A. in Mathematics from the University of Minnesota (1981).

In functional analysis, Gilsdorf focuses on locally convex spaces, contributing to topics like quasi-locally Baire spaces and fixed-point theorems. His ethnomathematics work explores Indigenous knowledge systems, including textile patterns among the Mazahuas, Hñähñu, and Atayal peoples, as well as Inca quipu systems and Otomi numerical traditions. He emphasizes gender dynamics and cultural preservation in mathematical practices.

Notable honors include a Fulbright Scholarship (2006–2007) at ITAM in Mexico and the Division of Mathematics and Actuarial Sciences Teaching Award (2014). His textbook Introduction to Cultural Mathematics (2012) is a foundational resource in the field. Gilsdorf has presented globally, including plenary addresses at international ethnomathematics conferences, and collaborates with institutions like the Universidad de Santiago, Chile.
