I'm a computer scientist by training (Ph.D. in programming language technology, 2003), currently working in industry. Real mathematics is more of a hobby.

In general, don't assume I necessarily know what I'm talking about, unless it's about computer science or formal logic. I dabble in various other fields that I've never taken courses in, mostly just by extrapolating from Wikipedia.
