The main goal of this research project is to study methods of statistical inference to identify different structural aspects in stochastic processes in high dimensions. We will consider principally the estimation of the graph of interaction in Markov random fields, also known in the statistical literature as graphical models, and the identification of change points for stochastic processes, both discrete and continuous. These two lines of research, particularly for models in high dimensions, constitute natural extensions of recent results obtained by me and my co-authors in the sabbatical research period in the Swiss Institute of Technology at Zurich.
