About me
I am a postdoctoral researcher working with Prof. W. Clem Karl in the Information Sciences and Systems (ISS) Laboratory at Boston University. I specialize in signal processing, inverse problems and machine learning. Currently I am continuing my Ph.D. research on improving image reconstruction and material discrimination in multi-energy X-ray tomography for security applications.

I received my B.Sc. from Ben-Gurion University, Israel, and my M.S. and Ph.D. from Boston University, all in Electrical Engineering. In the summer of 2012 I was an intern at Analogic Corporation in Peabody, MA, where I implemented 3D tomographic methods for medical applications. In 2007-2008 I was a teaching assistant at Boston University for 'Signal and Systems' and 'Probablity'. In 2005-2007 I worked for Winbond Israel as a Chip Design Engineer.
