Below are various notes and talks for classes or seminars
and expository papers (these also appear on the publications page).
Notes:
 Lectures on Morse theory and handlebodies given at the 2019 PCMI Undergraduate Faculty Program.
 Lectures from an introduction to algebraic topology for undergraduates with an emphasis on knot theory.
 Survey talk on open books decompositions at MSRI, May 2009. There is only a pdf version of these notes.
 Lecture notes from the 2006 PCMI. These notes
are on "Conatact geometry and lowdimensional topology" and focus on
the techniques used to apply contact geometry to questions in
lowdimensional topology. In particular, they cover perturbations of
foliations into contact structures, symplectic handle attachment and
symplectic caps. These note were written by Shea Vick. There is only a pdf version of these
notes.
 Notes on convex surfaces from a contact
geomety class. Last revised July 2004 (very rough form!) pdf and ps.gz
 Very basic notes on sheaves and divisors.
These were from a series of seminars I gave as a graduate student some
time in the early 90's. These should definitely be used at your own
risk! pdf and ps.gz
