Dr. Herden was born in Münster (Germany) and raised in Essen (Germany) where he received most of his education. His interest in mathematics got sparked at an early age and resulted in a vivid participation in various mathematical competitions throughout junior and senior high school. He finished his high school career in 1999 as the most successful participant of the German Math Olympiad (5 first, 1 second and 1 third prize) and is currently ranked #2 in the Hall of Fame of this prestigious competition. Further achievements of this early era include 3 first prizes at the German Federal Math Competition and 3 silver medals at the International Mathematical Olympiad (Argentina 1997, Taiwan 1998, Romania 1999).

Dr. Herden joined the Baylor faculty in 2014 having particularly strong affiliations to the algebra research group of the math department. Prior to this he has held various other positions including post-doctoral positions at the Hebrew University of Jerusalem, Israel (2007-2008) and at the University of Münster, Germany (2009-2010), a position as associate professor at the University of Duisburg-Essen, Germany (2013) and a visiting professor position at the Charles University in Prague, Czech Republic (2013-2014).

Academic Interests and Research:

Algebra: Dr. Herden's interest focuses on the interaction between algebra and set theory. This concerns specifically the existence and construction of large algebraic structures (e.g., groups, rings, modules) under set-theoretic considerations.

Set Theory: Dr. Herden is interested in any applications of set theory and infinite combinatorics to other fields of mathematics, most notably to algebra. This research is inspired by Saharon Shelah and his proof of the undecidability of the Whitehead problem.

Combinatorics: More recently, Dr. Herden has also become interested in applications of finite combinatorics. He has contributed to incidence algebras, symplectic geometry, invariant theory, maximal operators, and ergodic theory. This research is influenced by Richard P. Stanley.

In addition, Dr. Herden has a long-running interest in promoting mathematically talented high school students. He is a current member of the problem proposal committee of the German Mathematical Olympiad (DeMO).
