I am a Senior Lecturer (Assistant Professor) at the Einstein Institute of Mathematics, at the Hebrew University of Jerusalem, Israel.
I am interested in mathematical physics, chaos, and pseudo-randomness. Some of my research interests are non uniformly hyperbolic dynamics, thermodynamic formalism, symbolic dynamics, entropy theory, dimension theory, smooth systems with 0 exponents, and generalized physical measures.
