Contact details

I don't have a secretary, and I try to avoid distractions when I'm working on a tough problem. Therefore, I prefer to let the (initial) communication run through email. You can reach me through tjalling(at) I check e-mail regularly, so normally you can expect a response within two (working) days.

  • My other website,, contains a huge amount of information on DEB and GUTS modelling in eco(toxico)logy. It includes Matlab software, (links to) e-books, lists of publications, etc.
  • Roman Ashauer's website about models in ecotoxicology at: His site contains many more useful links for the modelling enthousiast.
  • The website is dedicated to robust and user-friendly software to run GUTS analyses. It offers free downloads for a standalone Windows version as well as a Matlab-based version.
  • Bongers EcoTox Services is run by Marina Bongers. She also offers more standard GUTS analysis in a regulatory context (with me - Tjalling Jager - as a scientific advisor).
  • The DEB Node at Akvaplan NIVA, where Starrlight Augustine is currently working. This group has organised the 2017 DEB course and symposium. See also the other DEB nodes in DEBnet.
