Christina Goldschmidt

A (reasonably non-technical) account I wrote of some recent work on minimum spanning trees.

Research interests
- I wrote my Ph.D. thesis on various aspects of the structure of random hypergraphs, with particular emphasis on the use of stochastic process methods. I have worked extensively on processes of coagulation (or coalescence) and fragmentation. More recently, I have been working on scaling limits for random trees and graphs.
