Vlad Popovici

My research is focussed on statistical methods for pattern recognition with a special emphasize on their application to life sciences, mainly in bioinformatics and computer aided diagnosis. Current research topics include the design and analysis of sparse classifiers and clustering techniques in high dimensional feature space.
