I'm a postdoc working with Kostas Bekris and Jingjin Yu at Rutgers University.
I obtained my BSc, MSc, and PhD in Computer Science at Tel Aviv University, where I was fortunate to work with Dan Halperin at the Computational Geometry Lab.
My PhD research focuses on coordinated motion planning for multiple moving agents/bodies. I've been deepening our understanding of what makes key problems computationally hard, identifying new algorithms and pushing tractability frontiers.
