Biography

I received my B.Sc., M.Sc. (summa cum laude), and Ph.D. (summa cum laude) degrees in electrical engineering at 2000, 2006, and 2011, respectively, from the Ben-Gurion University of the Negev. During 2000 to 2007, I worked for WideMed and EarlySense companies in development of algorithms for biomedical signal processing. From 2010 to 2012, I was a postdoctoral fellow in the Department of Electrical Engineering and Computer Science, University of Michigan, Ann Arbor, MI, USA, with Prof. Alfred Hero's group. Since October 2013, I'm a faculty member in the Department of Electrical and Computer Engineering, Ben-Gurion University of the Negev.
