At the moment I am a psychotherapist with a private practice in London, UK. I specialise in relationships, sex, gender, trauma, dissociation, and diversity. I do some talks, blogging, research, peer review, contribute to professional groups, and some activism, including on Facebook.

I have had a “first career” of 30 years as an international businessman working for an oil multinational. I have a masters in Development economics, econometrics and statistics from Erasmus University in the Netherlands. My whole life I have been interested in and close to computers. I worked on mainframe IBM S/360 and a big Univac in 1969. Was on the Arpanet in the mid-1970s, and started with email in the early 1980s. I have coding experience in a number of languages, old and new. I have moved from using Apple machines to using mostly Linux on my personal laptops and workstations; I've also switched from iPhone to Android.

I want to expand my contribution to Wikipedia by editing and improving Wikipedia articles in the fields of psychology, psychotherapy, sexuality, and possibly social science in general, which I don’t think are as good as in many other subjects in scope or quality. However, my time to work on this is limited. Despite misgivings about misogyny, I have maintained a reasonable faith in the Wikipedia system, and admire many of their policies.

Re non-artificial languages, I am reasonably fluent in English, Dutch, German and French, and my Turkish has declined, but is still passable.

I am pretty keen on references and referencing systems, and pedantic when I write articles myself or when I review others’ contributions.
