Research interests: network monitoring and management, programmable networks, network security and streaming algorithms. Currently, I am working on building tools for network monitoring by tailoring streaming methods to the computational model and constraints of programmable switches.

Bio

I am a senior lecturer (assistant professor) and head of the RUNS lab at the Open University of Israel. Before joining the Open University I was a postdoctoral researcher at Princeton University, advised by Prof. Jennifer Rexford. I received a Ph.D. in Computer Science from Tel Aviv University, where I was advised by Prof. Yehuda Afek and worked in collaboration with Prof. Anat Bremler-Barr and the DEEPNESS lab.
I have received several awards including the Eric and Wendy Schmidt Postdoctoral Award for Women in Mathematical and Computing Sciences, Google EMEA Anita Borg Memorial Scholarship and was the second place winner in the Broadcom Foundation University Research Competition. I was recently named one of the Rising Stars in Networking and Communications of 2020 by the N2Women Organization.
