I love cycling, and used to be the adviser to the Cal Cycling Club:


I also love music, especially the jazz of Patricia Barber:

Partial manuscript of

Lectures on Logarithmic Geometry

(Version of November 27, 2015)

(email me for password)

I will be working on revisions during the Fall of 2015, so there may be frequent updates. I have finished a revision of Chapter II and the first section of Chapter III, which includes the basics about log schemes. Some of the earlier sections are still subject to change. I welcome comments and criticisms, especially corrections of mistakes, of which I fear many remain.

      My specialty is algebraic geometry. This means, roughly, the study of the geometric properties of solutions of systems of algebraic equations. What I love about this subject is the interplay among geometry, algebra, analysis, and number theory. I am especially interested in applying differential and integral calculus in an algebraic setting. I am also involved in "logarithmic geometry," which is a systematic way of dealing with two important phenomena in mathematics: compactification and degeneration. Currently I am studying various aspects of algebraic differential equations, especially differential equations modulo p and differential equations with log poles.
