About me

I am a postdoc in the Probability group at ETH Zürich. I completed my PhD in the Cambridge Centre for Analysis (CCA) under the supervision of Nathanaël Berestycki.

I did my undergraduate and masters degrees at the University of Cambridge, Queens' College. I am also a former president of the Emmy Noether society for women in mathematics, for which I am now treasurer.

My CV is here.

Research

My research involves, broadly, the study of random systems at criticality. I am particularly interested in critical phenomena, scaling limits and more generally, random geometry. This is the study of the random curves and surfaces which arise as scaling limits of critical statistical physics models. I am especially interested in problems concerning the Gaussian free field, Schramm-Loewner evolutions and the relationship between the two.
