Research

Most of my work concerns elliptic curves and the "standard conjectures" for L-functions associated to arithmetic varieties. For my algorithms to compute special values of these L-functions see ComputeL (Pari-based), Magma (starting from V2.12, July 2005, see L-functions chapter) and W. Stein's SAGE

My Ph.D. thesis (2000, University of Utrecht, The Netherlands) is

``Deformations of p-divisible groups and p-descent on elliptic curves''

This is a link to the thesis, and on the right is a link to the genealogy tree 
of my Ph.D. ancestors  (light) and some of  my Ph.D. relatives (dark). 
Most of the data comes from the Mathematics Genealogy Project  
at Minnesota State University.
