I have an MS in Mathematics from the University of Bucharest, Romania, and a Ph. D. in Statistics from the University of Washington, Seattle (2000).
My research interests include machine learning and empirical processes theory. I am particularly interested in model selection and averaging (aggregation) in a variety of high dimensional parametric, semi-parametric and nonparametric models. My focus is on defining appropriate notations of sparsity and analyzing theoretically computationally efficient estimators tailored to sparse models, in problems where the number of parameters exceeds the sample size (" p > > n" problems). I have recently become interested in inference in high dimensional matrix models.
I currently serve as an Associate Editor for:
The Journal of the Royal Statistical Society, Series B.
The Bernoulli Journal
The Electronic Journal of Statistics ( EJS ), an open access journal of the Institute of Mathematical Statistics IMS .
I am a Series Editor for:
Chapman & Hall/CRC, Monographs on Statistics and Applied Probability (The Green Series) CH/CRC .
NSF DMS 10007444 Matrix estimation under rank constraints for complete and incomplete noisy data (2010 - 2013).
