Graham Jones

This site covers my interests in

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.

I have lived in the North West of Sutherland since 1983. I have painted landscapes and seascapes in oils and watercolours of the surrounding area throughout that time. it was my main source of income until 1991. I started doing digital paintings around 2004. I use my own program to do most of them. I still paint in oils and watercolours, but the digital ones are easier to upload.



Mathematical biology

Software: DISSECT, STACEY, SpeciesDelimitationAnalyser

The Software page has information about the BEAST packages DISSECT, STACEY, and DENIM, and two command line tools. These are SpeciesDelimitationAnalyser which analyses the output from either DISSECT or STACEY, and Migration Analyser is a which analyses the output from DENIM.

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.

Published articles

This excludes some papers with many authors, where my contribution was a a small fraction of the whole, and some old papers. A fuller list is at my researchgate profile.
