| Topographica is developed by a distributed team of researchers in
the United Kingdom, the United States, and Europe. The most active
current developers are:
- James
A. Bednar, Lead author and project manager, 2002 -
- Jim is a Lecturer at the University of Edinburgh. Parts of
Topographica were inspired by Jim's C++
LISSOM
simulator in use from 1995-2004, but Topographica was entirely
reimplemented in Python for extensibility and generality. Jim
reviews all code and is the last word on the design and
features.

Edinburgh, he is preparing Topographica's next major release.
