I am the admin of this site and this runs on Pleroma as a backend to Soapbox front-end. I am a medical doctor (ENT specialist), an epidemiologist (Environmental Health), and a professor of Epidemiology at the University of Canterbury in New Zealand. I am a member of the NZ FOSS and my hobbies include LEGO MOC building and wood carving and working on shells.
