About Me
I am a Ph.D. student at The University of Arizona, supervised by Dr. Michael Chertkov and Dr. Laurent Pagnier, specializing in the mathematical modeling of power grid systems. My work integrates probabilistic and statistical methods with object-oriented programming to study complex energy infrastructures. I have engaged in collaborative research at Los Alamos National Laboratory and provided consulting services for NOGA, the Power System Operator of Israel. These experiences have strengthened my ability to work across industry, national laboratories, and academic environments, contributing to multidisciplinary teams focused on modernizing and optimizing power systems. Looking ahead, I plan to continue my graduate studies with a focus on artificial intelligence, machine learning, and operations research. I am particularly interested in data-augmentation methodologies, including natural language processing, diffusion models, and large language models, and aim to apply these tools to advance research at the intersection of energy systems and intelligent algorithms.

A Methodology to estimate the probability of rare events in the transmission level power system dynamics.
We study rare failures associated with cleared faults in the transmission level power system dynamics described by swing equations. We assume that (a) prior to a fault, which may occur at random at any line, the system was in a balanced state; (b) fault is cleared within a few seconds; (c) a failure is counted at a power line of the system if during the post-fault transient (before or after the fault is cleared) power flow along the line exceeded a safe limit. The goal of this project is to develop a procedure to understand, estimate and analyze the dynamics of any given power grid that satisfies the linear swing equations. We are looking for a way to determine the distribution of the magnitude of the overloading of the system over time. This way we can determine how reliable and stable the system is even if there are failures in the grid for a random period of time.
