Two cats, one white with orange spots one tabby, curled up and asleep side by side on a bedspread.
Friend and collaborator pointing at a whiteboard. Whiteboard has one large spectral sequence diagram and two smaller spectral sequence diagrams. Many colors used.

Email from a student. Transcription: “Hey Jackson, Just wanted to say I really enjoyed your lecture in 208 A today. I left with a much stronger understanding of the day's concepts than I typically do. You were very approachable while also appealing knowledgeable, and I wouldn't have been nervous that my questions were too basic/obvious. It's hard to balance knowing and teaching with approachability and down-to-earth-ness, but I think you did it well. That's all, have a good rest of your week!”
Me, standing by my poster at a conference. Others standing nearby, listening as I explain
A middle column from a poster, with math text and some diagrams. In more detail, there are two sections on this poster. The first section outlines my main result, a computation of the ring of cooperations for a particular motivic spectrum by an Adams spectral sequence. The second section goes into a key step in my argument, an algebraic Atiyah-Hirzebruch spectral sequence. Roughly, the homology of my input to this Adams spectral sequence decomposed into a family of well-behaved modules. The first of these modules is, algebraically, a 3 cell complex, and a complicated Atiyah-Hirzebruch spectral sequence can be employed to compute its Ext group. The graphic below shows the cell complex, a heuristic for this aAHSS, and the charts which are attached to each cell in the algebraic cell complex. Woof!
Photo taken from the montlake bridge, which goes over the connection between lake Washington and lake union, on my walk to school. Beautiful blue sky, no clouds, mountains barely visible at the tree line.
