Eleanor Archer


I am in my final year of the MASDOC programme, supervised by Dr. David Croydon and Prof. Daniel Ueltschi. Previously, I completed my BA and MMath at King’s College, Cambridge.

I spent July-December 2019 at RIMS, Kyoto University.

I am primarily interested in random walks on random media, particularly those relating to random trees and random maps. I am also interested in random permutations, and their applications to statistical physics.

Research Articles:

Brownian motion on stable looptrees, 2019, submitted.

Infinite stable looptrees, 2019, accepted in Electronic Journal of Probability.

Non-Academic Activities:

In 2018/19 I was the chair of the MASDOC SSLC, and was jointly responsible for organising the 2019 UK Joint CDT Colloquium. During my undergraduate degree, I took on a variety of roles on student committees, including as captain of King's College Boat Club. I also undertook an actuarial internship from June-September 2014.
