| Research experience: | From 1979-1983 I worked as a Ph-D student in Leiden, under
supervision of Rob Tijdeman and Frits Beukers. The purpose of my
Ph-D research was to give as good as possible estimates for the number
of solutions of Diophantine equations, using techniques from
Diophantine approximation.
From 1984-1988 I worked as a researcher at the CWI in Amsterdam in the cryptography group of David Chaum. There, my research was focused on cryptographic protocols and on the Data Encryption Standard. In 1988 I went back to Leiden and continued the research I started as a Ph-D student. From 1988-1993 I was a KNAW fellow, and since 1993 a Universitair Docent in the Leiden number theory group. Since then I have been working on Diophantine approximation, Diophantine equations and Diophantine inequalities, in particular on matters such as the Thue-Mahler equation, discriminants and resultants of binary forms, decomposable form equations, S-unit equations, Faltings' Product Theorem, Schmidt's Subspace Theorem, symmetric improvements of Liouville's inequality, approximation of algebraic numbers by algebraic numbers of bounded degree. My research in the past few years concerns generalizations and refinements of Schmidt's Subspace Theorem, estimating the number of equivalence classes of pairs of binary forms with given resultant, approximation of complex algebraic numbers by algebraic numbers of bounded degree, complexity of expansions of real algebraic numbers with respect to a given base, multiply monogenic orders, effective finiteness results for points from the intersection of a subvariety of a linear torus and a group of finite rank over the algebraic closure of Q, effective results on unit equations over finitely generated domains. I am presently writing a book with Kálmán Györy on Diophantine problems related to discriminants of polynomials. | ||||||||||||||||||||||||||||
