Here is a recent talk I gave called Brain Control - It's Not Just for Mad Scientists

This covers my research inspired by Parkinson's disease, epilepsy, and cardiac arrhythmias.

with Kaia and Teagan

Many of you are probably here for Teagan's website or Kaia's website.
In my "spare time" I write concert reviews for A list of my reviews, plus interviews, etc, is available here.
Here's a webpage I created on The Mathematics of the Movie "21". This includes discussions of The Fibonacci Series, The Monty Hall Problem, and the Newton-Raphson Method. I don't say much about "card counting" for Blackjack because this is thoroughly covered elsewhere on the web.

    Erdös and Bacon numbers

  • My Erdös number is 4: I've written a joint paper with Edgar Knobloch, who has written a joint paper with Martin Golubitsky, who has written a joint paper with Bruce Rothschild, who wrote a joint paper with Paul Erdös. There may be other paths also! For more information, see the Erdös Number Project Home Page .
  • I played two small parts in a movie called Post Concussion directed by Danny Yoon. If you get a chance, go see it!!! Or, order from . My Kevin Bacon number is still infinity.
