I'm broadly interested in theoretical computer science and its interplay with combinatorics.
Here there be brambles and trees and sunflowers, arthur, merlin, alice, and eve; what else could this be if not the garden of earthly delights?
I have a small side interest in neat geometric ideas, and am trying to learn other things too; it's tough, but we'll get there someway or somehow!
