I am currently working in
Compugen as an algorithm designer. Previously I worked as a teaching assistant in the Hebrew University in Jerusalem, studying for a Ph.D. in mathematics which I haven't completed.My wife Irit is a social worker, working with the mentally disabled.
I am interested in mathematics, especially algebra and number theory (groups, fundamental domains, Hecke operators, number fields).
I enjoy singing in a choir, hiking and walking, and watching the stars when the sky is dark and clear.
