**Qualifications:**

Habilitation in Mathematical Physics, University of Leipzig, 2000

Ph.D. in Theoretical Physics, University of Kaiserslautern, 1992

**Biography:**

Dr. Kirsten joined the Baylor faculty in January 2003. Prior to
coming to Baylor he held research positions in Italy, Spain,
Germany and England. After his Ph.D. he was a visiting professor
at the University of Trento, Italy (1992-1993). He received an
Alexander von Humboldt Fellowship to do research at the University
of Barcelona, Spain (1993-1995). From there he was lured away with
a Fellowship from the German Research Foundation (DFG) to go to
the University of Leipzig, Germany (1995-1999). A Fellowship from
the Engineering and Physical Sciences Research Council enabled him
to spend time at the University of Manchester, England
(1999-2001). Finally, before coming to Baylor, he was a
post-doctoral Associate at the Max-Planck Institute for
Mathematics in the Sciences in Leipzig. Dr. Kirsten is originally
from Trier, Germany. He is married to Anja Moehring and he enjoys
all kinds of sports, hiking, languages and spending time with
friends.

**Academic Interests and Research:**

Dr. Kirsten's research is in mathematical physics. In particular,
he is interested in spectral theory of partial differential
operators, its applications in quantum field theory and its
ramifications in differential geometry.

**Teaching Interests:**

Dr. Kirsten's teaching interests range from introductory calculus
classes to specialized courses for Ph.D. students. He (together
with P. Loya, University of Binghamton, NY) is in the process of
writing a textbook on complex analysis and its applications.
