I received my Ph.D degree from Tel-Aviv University in 2013. Currently, I am a researcher at the School of Mechanical Engineering in collaboration with Prof. Alexander Gelfgat and Prof. Eyal Heifetz and working as lecturer at Department of Biomedical Engineering.

My research experience lie in the fields of computational fluid dynamics, hydrodynamic stability analysis, parallel computing (MPI).
