Baruch Barzel (Hebrew: ברוך ברזל; March 19, 1976) is an Israeli physicist and applied mathematician at Bar-Ilan University,[1] a member of the Gonda Multidisciplinary Brain Research Center[2] and of the Bar-Ilan Data Science Institute.

[3] His main research areas are statistical physics,[4][5] complex systems,[6][7] nonlinear dynamics and network science.

In the following years, Barzel and colleagues developed a theoretical framework to predict the observed behavior of complex networked systems: their patterns of information flow;[11] the timescales of their signal propagation;[12] their resilience against failures and disruptions[13][14] and their recoverability.

[15] During the COVID-19 Pandemic Barzel's lab published the alternating quarantine strategy[16] to mitigate the spread of SARS-CoV-2 alongside continuous socioeconomic activity.

[19] Barzel completed his Ph.D. in physics at the Hebrew University of Jerusalem, Israel as a Hoffman Fellow.
