Publications

My broad interests lie in the areas of (statistical) graph signal processing for the study of networks, neuroimaging data analysis, and robust, distributed, as well as sparsity-aware signal processing. See also the list of my publications in Google Scholar, ORCID, IEEEXplore, or DBLP. A (somewhat outdated) overview of my research can be found here.
