I am a senior lecturer (assistant professor) and Taub Fellow at the Faculty of Computer Science in the Technion — Israel Institute of Technology. I've completed my PhD at Tel Aviv University, where I was fortunate to be advised by Noga Alon. After that, I was a postdoc at Weizmann Institute (hosted by Moni Naor) and later at Harvard University (mentored by Madhu Sudan), an instructor in applied mathematics at MIT, and a research fellow at Simons Institute. Research Interests: Theoretical and algorithmic foundations of big data, focusing on theoretical modeling of modern massive, complex, and challenging computational environments. Areas of interest include sublinear-time algorithms; algorithms and society; beyond worst case analysis of algorithms; robustness and privacy; knowledge representation; and complex networks. Prospective Students: I am looking for motivated students interested in algorithmic research "between theory and practice". Feel free to reach out!
