Research interests: graphical models, covariance matrix estimation, convex analysis, tensors, algebraic and combinatorial methods in statistics.

Editorial responsibilities: JRSS-B, Biometrika, Scandinavian Journal of Statistics, Algebraic Statistics.

Highlights: Join us on Tuesdays: Brown Bag Seminar. Laplacians, multivariate extremes and algebraic statistics (November 4-8, 2024), Eindhoven, The Netherlands. UAI 2024 will happen in Barcelona! I am looking for graduate students interested in mathematical statistics and its aspects related to combinatorics, convex analysis, and tensors. For recent PhD graduates: There is a number of open calls for postdoctoral positions at UofT - see here, here, here, here, and here (the latter is particularly suitable for underrepresented groups). GOLAZO R package for a general assymetric regularization of the log-likelihood in Gaussian graphical models. To install, just call in R: devtools::install_github("pzwiernik/golazo")

Math to the people (four axioms of Federico Ardila): Axiom 1. Mathematical potential is distributed equally among different groups, irrespective of geographic, demographic, and economic boundaries. Axiom 2. Everyone can have joyful, meaningful, and empowering mathematical experiences. Axiom 3. Mathematics is a powerful, malleable tool that can be shaped and used differently by various communities to serve their needs. Axiom 4. Every student deserves to be treated with dignity and respect.

I am on leave from: Department of Economics and Business Universitat Pompeu Fabra BSE Data Science Center Statistics group at UPF
