About
I am an Assistant Professor in the Department of Mathematics and Statistics at Auburn University, where I joined in August 2025. My research develops statistical methods for complex data, with a focus on change point detection and inference, nonparametric estimation, and high-dimensional time series.
Previously, I was a Harrison Early Career Assistant Professor at the University of Warwick (2023–2025). I held postdoctoral positions at Pennsylvania State University with Runze Li, Université catholique de Louvain with Johan Segers, and the University of Warwick with Yi Yu. My work at Penn State and Louvain was supported by an SNSF Postdoc.Mobility Fellowship.
I received my Ph.D. in Statistics from the University of Geneva in 2021, advised by Maria-Pia Victoria-Feser and Stéphane Guerrier, and my M.Sc. in Statistics from the University of Illinois at Urbana–Champaign in 2015.
