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.

Working notes up to 2010.

Working notes 2011. Allopolyploids.

Working notes 2012. Allopolyploids.

Working notes 2013. Allopolyploids, species delimitation.

Working notes 2014. Species delimitation (DISSECT).

Software: DISSECT, STACEY, SpeciesDelimitationAnalyser

Software for species delimitation. Includes a package for DISSECT in BEAST2, a beta version of the BEAST2 package STACEY, and jar file for using SpeciesDelimitationAnalyser which analyses the output from either DISSECT or STACEY. Note that DISSECT is now available in BEAST 1.8.1.
