This site is devoted to my interest in mathematical biology, especially phylogenetic analysis and macroevolution.
A bit about me. I completed a PhD in pure maths back in 1983. From the early 1990s to 2007 I mainly worked in the area of pattern recognition (more likely to be called machine learning or computer vision these days). I was self-employed, and wrote and marketed the optical music recognition program SharpEye. I worked at the Centre for Theoretical Biology in Gothenburg in 2011 and 2012. This was on phylogenetic methods for dealing with allopolyploids. I enjoyed this, but I do not want an academic career. I am not very rich, but I can afford to pursue my scientific interests without grants. I am in favour of open notebook science.

The Software page has information about the BEAST packages DISSECT and STACEY, and a jar file for using SpeciesDelimitationAnalyser which analyses the output from either DISSECT or STACEY.
If you have problems using these programs, please use the BEAST-users forum. I don't check the forum as often as emails, so feel free to send me an email as well.
