I am a PhD student in the Statistics, Probability, and Machine Learning Research Group at Universitat Pompeu Fabra (UPF), supervised by Piotr Zwiernik. I will hold the "la Caixa" Doctoral INPhINIT Fellowship starting in October.

My research interests include robust statistics, matrix analysis, and inequalities.

Previously, I completed my bachelor's and master's degrees at the University of Toronto and the University of Chicago, respectively.
