| Topographica is developed by a distributed team of researchers in
the United Kingdom and the United States. The principal developers are:
- James
A. Bednar, Lead author and project manager, 2002-
- Jim is a Lecturer at the University of Edinburgh. Topographica
was inspired by Jim's C++ LISSOM
simulator, but is entirely reimplemented in Python for
extensibility and generality. Jim reviews all code and is the
last word on the design and features.
- Jan Antolik, September 2006-
- Jan is working on his PhD thesis about feedback from V2 to V1 at the
University of Edinburgh, but also contributes optimizations and
other code to Topographica.
- Chris Ball, September 2005-
- Chris works on nearly every part of Topographica, and is also working on
modeling
motion aftereffects in LISSOM.
- Yoonsuck Choe, 2002-
- Yoonsuck is an Assistant Professor at Texas A&M University.
He is implementing spiking neuron support,
primarily for integrate-and-fire neurons, and contributed
significantly to the web site and other graphical design.
- Judith Law, September 2005-
- Judith is working on her PhD thesis about V1 surround modulation
and species differences at the University of Edinburgh, but also
contributed tuning curve support and various GUI improvements.
- Chris Palmer, September 2005-
- Chris is working on his PhD thesis about spatial frequency
representations in V1 at the University of Edinburgh, but also
maintains receptive field plotting support and other analysis code.
- Jefferson
Provost, 2002-
- Jeff is a postdoctoral researcher in the Neuroscience Department at
the University of Pittsburgh. He wrote the initial GUI
implementation (first in Scheme, then in Python), and the first
Python version of most of the base classes (Sheet, CFSheet,
CFSOM, ParameterizedObject, LISSOM, etc.), but is now primarily
a Topographica user rather than a developer.
- Roger Zhao, September 2006-
- Roger is working on his PhD thesis about face aftereffects at the
University of Edinburgh, and contributes face-related code to
Topographica.
Other significant contributors include:
- Risto
Miikkulainen, Principal investigator, 2002-2005
- Risto is a Professor of Computer Science at the University of
Texas at Austin.
- Julien Ciroux, October 2005 - April 2006
- Julien recently received an MSc from the University of Edinburgh
(topic: modeling the McCollough effect in LISSOM). He implemented the
new plotting subsystem in 0.8.2 and other GUI-related functions.
- Foivos Demertzis, September 2006 - May 2007
- Foivos is working on his undergraduate degree at the
University of Edinburgh, with a project of developing
more sample models for Topographica.
- Judah De Paula, 2004-2006
- Judah has now completed his PhD at the University of Texas (topic:
modeling the development of color maps in LISSOM). He was
responsible for the initial Windows support, and implemented the
first complete plotting and related GUI code.
- Alan Lindsay, September 2005-May 2006
- Alan finished his undergraduate degree at the
University of Edinburgh in summer 2006. Alan developed the
Model Editor, a graphical interface for specifying Topographica
models by selecting and connecting pre-defined components.
- Louise Mathews, September 2005-May 2006
- Louise finished her undergraduate degree at the
University of Edinburgh in summer 2006. She implemented sample
models of visual cortex maps published by other research groups.
This effort will help ensure that Topographica has
general-purpose support for maps, and will build a library of
starting points for future studies (e.g. comparison studies).
- Ruaidhri Primrose, September 2006 - May 2007
- Ruaidrhi is working on his undergraduate degree at the
University of Edinburgh, with a project of developing
more sample models for Topographica.
- Yiu Fai Sit,
May 2005-
- Sit is a PhD student at the University of Texas (topic:
the role of feedback in a hierarchical LISSOM model of V1 and
V2). He was responsible for making the first Topographica
implementation of LISSOM match the C++ version, and for
writing C code to optimize key Topographica functions.
