As of spring 2007, I'm currently a seventh-semester graduate student in the Mathematics Department at Penn, living in West Philadelphia. In May, I will be leaving grad school and moving to Connecticut. My permanent email address is [my-first-name] [at] [my-last-name] [dot] [com].
Before coming to Penn, I was at Swarthmore College, where I got degrees in mathematics and in computer science.
I am a department-approved tutor at Penn for all undergraduate math, as well as for Maple. For new students, I charge $60 per hour; group rates are available starting at $90 per hour for two people. After spring 2007, I will not offer tutoring. Inquire by email: schak [at] math [dot] upenn [dot] edu.
I am not teaching this year, but I am doing one of the help sessions on Wednesdays this semester.
I TAed for Math 241 in Spring 2006 and Fall 2005, and for Math 114 in Spring 2005.
My email in the math department is schak [at] math.upenn.edu. My office is room 4C17 in David Rittenhouse Laboratories, and my phone number there is 215-898-5196. I have a personal webpage at www.schak.com. People who know me personally can ask me for my address, personal email address, cell number, AIM screen name, ICQ number, LiveJournal username, social security number, and ATM PIN.
