I am a PhD student in mathematics at CUNY Graduate Center. My advisor is Dennis Sullivan. My research interest is algebraic topology. These days I've been thinking and learning about homotopy theory of algebraic structures, string topology, and other related topics. In this website I plan to post notes (mostly expository for now) among other things.
