i run a problem-solving consulting shop called QED which focuses primarily on signal processing, machine learning, and algorithm design. some of the previous companies that i have worked at include the Jet Propulsion Laboratory, apple computers, and nec research labs. i studied computer science and electrical engineering at berkeley, followed by a mathematics masters' degree and phd in electrical engineering at stanford. for a copy of my old stanford research site, please click here.
most of this site is devoted to some of my interests, particularly riddles and mathematical puzzles. this topic consumes most of the visitor bandwidth, and almost all of the highly educational forum content. there's also some stuff on psychology, fractals, and other neat things. if you're into math and/or puzzles though, i think you'll enjoy the forum, and i invite you to join. it's an archive of discussions for thousands of puzzles at all levels of difficulty. new problems arise almost every hour, and we have members spanning all ages, countries, and professions.
btw, if you're wondering why this site is on a berkeley server, my undergraduate studies in EECS were done at berkeley. it's a big hassle to move everything due to the forum.
