I am a postdoctoral researcher at the Copenhagen Causality Lab at the University of Copenhagen. Previously, I was a PhD student under the supervision of Niels Richard Hansen :sunglasses:

My research interests are in mathematical statistics and machine learning, with a focus on model-free statistical methods. My PhD work centered on statistical inference for conditional association measures in complex data settings, including unstructured covariates and counting processes.

Keywords: nonparametric statistics, model-free methods, covariate adjustment, local independence, double/debiased machine learning, continuous-time stochastic processes.

Aug 31, 2024 I submitted my PhD Thesis! :tada: It is publicly available. In addition to the already published and arXived papers, the thesis contains a new manuscript titled Assumption-lean Aalen regression, along with a brief introductory chapter. I will be continuing as a postdoc to complete projects from my PhD studies.
Apr 18, 2024 I gave a plenary talk at EuroCIM about our recent work on efficient adjustment :nerd_face: :speech_balloon:
[Handout version of slides]
Feb 21, 2024 New project: Efficient adjustment for complex covariates: Gaining efficiency with DOPE :rocket: :rocket: :rocket: [arXiv]
Oct 29, 2023 Our paper, Nonparametric conditional local independence testing, got published in The Annals of Statistics! :tada: :tada: :tada: The published version with supplementary material is also available in a single PDF at nrhstat :sunglasses:
Jan 27, 2023 My two side projects (spin-offs from my graduate studies) have been published in Journal of Mathematical Imaging and Vision and Journal of Algebraic Combinatorics.
