Posters

After I exceeded a couple dozen posters, it seemed like it probably didn’t make sense to list them all individually anymore. But in the event you saw one somewhere (or saw the abstract for one), and you’d be interested in getting a copy, just get in touch and I’d be more than happy to oblige.

Theses

  • Caltech Ph.D. thesis (technically a “dissertation”): link | PDF
  • Fordham undergraduate honors thesis: PDF | color figures: 8, 9, 11, 12, 13 (inset)
