Gerald Teschl (born 12 May 1970 inGraz) is anAustrianmathematical physicist andprofessor ofmathematics.He works in the area ofmathematical physics; in particular direct and inversespectral theory with application to completely integrablepartial differential equations (soliton equations).

After studyingphysics at theGraz University of Technology (diploma thesis 1993), he continued with aPhD inmathematics at theUniversity of Missouri. The title of his thesis supervised byFritz Gesztesy wasSpectral Theory for Jacobi Operators (1995). After apostdoctoral position at theRheinisch-Westfälischen Technische Hochschule Aachen (1996/97), he moved to Vienna, where he received hisHabilitation at theUniversity of Vienna in May 1998. Since then he has been a professor of mathematics there.

In 1997 he received theLudwig Boltzmann Prize from theAustrian Physical Society, 1999 thePrize of the Austrian Mathematical Society. In 2006 he was awarded with the prestigiousSTART-Preis by theAustrian Science Fund (FWF). In 2011 he became a member of theAustrian Academy of Sciences (ÖAW).

His most important contributions are to the fields ofSturm–Liouville theory,Jacobi operators and theToda lattice. He also works inbiomathematics, in particular in the novel area ofbreath gas analysis, and has written a successful undergraduate textbook (Mathematics for Computer Science, inGerman) with his wifeSusanne Teschl.
