Jhonatan Tavori @ TAU

About Me

Hi there! I am a PhD Student at the Blavatnik School of Computer Science, Tel Aviv Univesity, under the supervision of Prof. Hanoch Levy.
Recently, I was a visiting scholar at Columbia University, working with Prof. Gil Zussman in the Wireless and Mobile Networking Lab.
My fields of interest revolve around networking and security, with a research focus on analyzing the performance of stochastic networks under attack. Currently, I am concentrating on optimizing the operation and budget utilization of cloud applications, with a particular emphasis on addressing the challenges associated with distributed microservices architectures.
