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.
