Seminars and workshops
Upcoming:

Directed Reading Program Network conference.
An informal workshop on best practices for undergraduategraduate Directed Reading Programs in mathematics. See website for details.
Of current interest:
Below are the webpages (including notes or readings) for some reading groups, and the Grad Student Summer school that I organized in the past.
Mathematical Outreach
 I am involved in the DRP network, an NSFfunded project to support
undergraduategraduate independent study/reading programs in mathematics.

I mentored students in the University of Chicago REU in 2009 and 2011. You can find information and student papers
here.
 I was also involved for many years wtih the U Chicago Directed Reading Program.
 And you may have also seen me at Mathcamp!
 Here's an amazing website created by Sophia Ellia, it eventually inspired her undergraduate thesis that I supervised.
