My research is in the fields of Harmonic Analysis and Geometric Measure Theory, with connections to Applied Mathematics. One part of my research lies on the interface between Harmonic Analysis and Geometric Measure Theory. It focuses on the theory of Quantitative Rectifiability. The goal is a quantitative study sets or measures, in a metric space (such as Euclidean space). This study is done via multiscale analysis. A second part of my research lies on the interface between Applied Mathematics and Harmonic Analysis or Geometric Measure Theory. In many applications one is given a large data set, represented as a subset of a metric space. A standard example is a subset of a high dimensional Euclidean space. One seeks to faithfully represent a large portion of this data set as a subset of a low dimensional Euclidean space.
I did my undergraduate studies at the Hebrew University, in Jerusalem, Israel. In May 2005 I received my Ph.D. in mathematics from Yale University. It was done under the supervision of Peter Jones. From Fall 2005 to Spring 2009 I was an NSF Postdoc/Hedrick Assistant Professor at the UCLA mathematics department. In fall 2009 I started as an Assistant Professor at the Stony Brook mathematics department. I am supported by the NSF. In the past I was also supported by a fellowship from the Alfred P. Sloan Foundation. (See Funding).
