Thomas Hermann Geisser (born February 28, 1966, in Wuppertal) is a German mathematician working at Rikkyo University (Tokyo, Japan). He works in the field of arithmetic geometry, motivic cohomology and algebraic K-theory.

From 1985 Geisser studied at Bonn University under the supervision of Günther Harder and obtained a master's degree in 1990. He continued to obtain a PhD under the supervision of Christopher Deninger at the University of Münster; the title of his thesis is A p-adic analog of Beilinson's conjecture for Hecke characters of imaginary quadratic fields. ^[1]

Geisser spent three years at Harvard University as a visiting scholar and visiting fellow, respectively. After further stays in Essen, University of Illinois, Urbana-Champaign and Tokyo University, he became assistant professor at the University of Southern California, and was promoted to associate professor in 2002 and professor in 2006. ^[2]

After visiting Tokyo University again he became a professor at Nagoya University in 2010, and moved to Rikkyo University in 2015 ^[3]

He received a Sloan Research Fellowship (2000) and a Humboldt Prize (2021). ^[4]

He is editor for Documenta Mathematica ^[5] and managing editor for Commentarii Mathematici Universitatis St.Pauli. ^[6]
