At work I manage the recording and production studios, equipment loan service, plus various specialist networks, services, and technical training at the University of Salford.
I'm a member of the British Computing Society and the Institute of Science and Technology, and completed my Avid Pro Tools Operator training in the distant past. Strictly speaking, I'm also an Apple Certified Technical Coordinator from back when that was a thing.
My specialist subjects are studio infrastructure and systems design, particularly network and computing technologies for creative applications. My academic background is in Psychology, where my focus was on human-computer interaction and auditory perception.
Tinker time usually boils down to very simple microcontroller-based hardware design or software for embedded systems, though this has to compete with family and snowboarding, which often win. I also appear to have become a bit of a computer security geek in recent years.
