He studied mathematics at the University of Vienna and finished with a Ph.D. thesis on uniform distribution under the supervision of Edmund Hlawka. He received his habilitation at TU Wien in 1983. Currently he is a professor at the Institute for Analysis and Number Theory at TU Graz. Previous positions include head of the Department of Mathematics and Dean of the Faculty of Mathematics, Physics and Geodesy at TU Graz, President of the Austrian Mathematical Society,[1] and Member of the Board (Kuratorium) of the FWF, the Austrian Science Foundation.

His research deals with Number theory, Analysis and Actuarial mathematics, and in particular with number theoretic algorithms, digital expansions, diophantine problems, combinatorial and asymptotic analysis, quasi Monte Carlo methods and actuarial risk models. Among his contributions are results in discrepancy theory, a criterion (joint with Yuri Bilu) for the finiteness of the solution set of a separable diophantine equation, as well as investigations of graph theoretic indices and of combinatorial algorithms with analytic methods. He also investigated (with Istvan Berkes and Walter Philipp) pseudorandom properties of lacunary sequences.

In the theory of equidistribution he solved (with Harald Niederreiter) an open problem of Donald Knuth's book The Art of Computer Programming, by showing that the sequence is completely uniformly distributed for almost all real numbers .

He is interested in the history of Alpinism and is also an avid climber.

In 1985 he received the Prize of the Austrian Mathematical Society.[2] Since 2004 he has been a Corresponding Member of the Austrian Academy of Sciences. In 2017 he received an honorary doctorate from the University of Debrecen. He taught as a visiting professor at the University of Illinois at Urbana–Champaign and the Tata Institute of Fundamental Research. In 2017 he was a guest professor at Paris 7; currently (until February 2021) he holds the Morlet chair[3] at the Centre International de Rencontres Mathématiques in Luminy.
