#### Brief Bio

Dr. Tangedal earned his Ph.D. from the University of California at San Diego in 1994 under the direction of Harold Stark. After holding various positions at the University of Vermont, Clemson University, and the College of Charleston, he joined the faculty at UNCG in 2007. His research interests lie in algebraic number theory with a particular emphasis on explicit class field theory. This involves the constructive generation of relative abelian extensions of a given number field using the special values of certain transcendental complex and p-adic valued functions. Almost all of his research to date is concerned with a system of conjectures, due to Stark and others, that make class field theory explicit in a precise manner using the special values mentioned above.
