The logo above is a configuration of 3 discs and 2 half-discs inside the unit half-disc. This belongs to the swiss cheese operad. My thesis is centered on the study of this object.
You can find various notes, mostly handwritten, on this page. These are from seminars, conference talks, and conversations.
Many links to papers and websites related to my field of research are here. Roughly, this covers some homotopy theory, category theory, operads, and mathematical physics.
