See http://micro5.mscc.huji.ac.il/~jr-s/ for the group of people I work with.

Check  aboud the workshop on "Sparsity and Inverse Problems in Statistical Theory and Econometrics"

Born 1951, Israel; B.Sc. 1969 (The Technion, I.I.T., Electrical Engineering), M.Sc., 1980 (The Technion, I.I.T, Electrical Engineering), Ph.D. 1983 , (Statistics, The Hebrew University of Jerusalem).

Lecturer, 1984; Senior Lecturer, 1989; Associate Professor, 1990; Professor, 1992. More details.

Declared statistical interests: Asymptotic theory of estimators for semi-parametric/non-parametric models; statistical analysis of stochastic processes; survival analysis; detection of a change and signal processing.

I have learnt a lot in my life. Unfortunately, most of it about technicalities. Here are some details.
