Over 30 years modelling a wide range of biological systems.
The following lecture notes are available as PDF files and may take some time to download. The size of each file is given in brackets.
To my surprise, I discovered that my paper The behaviour of a model animal (Ludlow, 1976) is still being cited quite regularly. There are other papers and a Ph.D. thesis on the ‘Model Animal’. The fullest and most recent account is the Thesis, so I have scanned it in and made it available as a .pdf file.
