Don’t Start Me Talking…

This website contains almost all of the work I’ve done in my teaching and research careers. I work in “spatial analysis” broadly defined, with a major interest in soil geography. I’ve written many tutorials and examples, almost all using the R programming language and software environment for data science.

Please note I am (semi-)retired and do not have an own research programme at any research institute, so I can not supervise graduate students, postdocs, or visiting scientists. Som please do not write me asking to be my student or join my (non-existent) research group.
