I’m a P.hD. candidate @ Technion, Israel Institute of Technology, Supervised by Prof. Avi Ostfeld
My research focus is the optimization of water distribution networks.
Specifically, optimal operation under uncertainty conditions.
I’m passionate about mathematical programming, optimization algorithms,
Machine learning, and data analytics and their implementation for water, energy, and environmental applications
