Fritz Gesztesy’s  research centers around applications of operator and spectral theory to a variety of problems connected to mathematical physics.  He has lectured and held visiting positions at numerous institutions and supervised 7 Masters and 14 Ph.D. students.  Currently, he is editor in chief of the Journal of Spectral Theory (EMS).  He also serves as a co-editor of several journals and book series, edited a number of proceedings volumes and special journal issues, and co-authored a Springer book (now in 2nd edition with the AMS) and two Cambridge University Press monographs. Details can be found in his CV.

His professional honors include:

  • Alexander von Humboldt Fellowship, University of Bielefeld, Germany, 1980-81 and 1983-84.
  • Ludwig Boltzmann Award, Austrian Physical Society, 1987.
  • L.M. Defoe Distinguished Professorship, Dept. of Math., Univ. of Missouri, September 1996 until August 2001.
  • M. & R. Houchins Distinguished Professorship, Dept. of  Math., Univ. of Missouri, since January 1, 2002. 
  • Election to the Royal Norwegian Society of Science and Letters, Trondheim, Norway, January 1, 2002. 
  • Fellow of the American Mathematical Society, January 1, 2013.
