Research

`I like work: it fascinates me. I can sit and look at it for hours. ... some of the work that I have by me now has been in my possession for years and years' (Jerome K. Jerome, Three Men in a Boat, Chapter 15)

A lot of my research consists of theoretical (computational) studies in solar system dynamics.
Interests include:

Publications
Review of (Leonid) dust trail theories - how to predict meteor storms
