I am a distributed systems researcher, with extensive experience in developing efficient and intelligent distributed systems. My current research focuses on building sustainable computing and societal infrastructures, as well as designing resource-efficient and failure-resilient AI systems for resource-constrained edge environments. I am working with Prof. Prashant Shenoy and funded by the NSF CoDec Project to work computational decarbonization of computing and societal infrastructures.

I received my PhD in Computer Science from the University of Massachusetts, Amherst in May 2025. I also hold a Master’s degree in Computer Engineering from Helwan University, Egypt, and a Bachelor’s degree in Computer Engineering from the same university.

Before Joining UMass I worked as a Researcher in multiple Universities and also worked as a software engineer for many years.

My work has been published in top-tier conferences, e.g., ASPLOS, SIGMETRICS, INFOCOM, HPDC, e-Energy, SoCC, IoTDI, SEC, and IWQOS.

For more details please checkout my CV.

I am currently on the 2025-2026 academic job market. Please feel free to reach out!
