I am currently an adjunct in the Financial Engineering Program at the Polytechnic Institute of New York University. I have a PhD in applied math from NYU's Courant Institute and expertise in applied probability and stochastic processes. At least as importantly, I am a native speaker of English, and I do mean ***English***, NOT "mathematese". I pride myself on being able to explain complex concepts clearly (though I don't claim to be a telepath. I doubt I could explain continuous time Martingales to someone without, say, pre-calculus).
I ***DO*** have a computer with a web cam, and an active Skype account. (To prove it, I can tell you that long Skype sessions work best with audio only.).
I realize that I am not the low bid on this, but you've probably paid lots more for the course itself. Go with someone who can really explain things clearly. In fact, why don't you respond by asking me a question or two for a free sample!
