I am a retired teacher of 41 years. I taught Stock Market Game to students for about 25 years. I always encouraged my students to check biotech stocks as the game only lasted ten weeks an we were aiming for a good short term profit. As a result I became quite familiar with the patterns of the biotech industry. I have been quite successful investing in those stocks.
I am interested in both applied and theoretical mathematics so investing is a good outlet for me. I did a triple major in math, physics and astrophysics at the University of Toronto, and now I'm working on a double masters and phd in electrical/mechanical engineering at Penn State.
I'd say my investment strategy is generally just common sense and working with the financials and not the stories, which is pretty much how I interpreted Ben Graham's texts. I call it common sense, but half the articles on this website seem to seriously lack it, so maybe it's not that common.
My research interests are in artificial intelligence, machine learning, data mining, pattern recognition, signal processing, stochastic calculus, information theory, convex optimization etc.
