PROBABILITY, SEMINARS
April 9, 2024 1:30 pmHierarchical percolation is a toy model for percolation on Z^d that, much like percolation on Euclidean lattices, is expected to exhibit mean-field behavior in high dimensions, non-mean-field behavior in low...

ALGEBRAIC DYNAMICS, SEMINARS
April 4, 2024 4:00 pmLast summer, in this seminar, I introduced a dynamical system called "complex billiards" that extends the classical real billiards map to the setting of curves over algebraically closed fields. The...

CMSA Active Matter, SEMINARS, CMSA EVENTS
April 4, 2024 1:00 pmMaterials that increase in size offer intriguing possibilities for shape morphing applications. Here, we explore two such systems—swelling polyacrylamide hydrogels and expanding polyurethane foams. The hydrogels swell by absorbing water...
