I am a fourth-year PhD student in the College of Information & Computer Sciences, University of Massachusetts, Amherst. I am advised by Prof. Prashant Shenoy. I am affiliated with Laboratory for Advanced Software Systems. Before Joining UMass I worked as a Researcher and as an R&D engineer in multiple Universities. I also worked as a developer for a couple of years.

My research interests include cloud computing, software architecture and building large scale distributed systems. My current research focuses on building sustainable and energy-efficient systems. The work spans edge computing, green computing, energy informatics, and machine learning systems. For other details please checkout my resume.

• July 2023: I presented our presented our paper on the tradeoffs between carbon and energy efficiency in HotCarbon'23. (link).
• June 2023: I presented our low latency model-serving at IWQOS'23 which took place with FCRC.(link).
• May 2023: I received an MS degree in Computer Science, from UMass.
• April 2023: Our network accelerated Model-serving paper was accepted in IWQOS'23 (link).
• Jan 2023: Our Dělen paper was accepted in IoTDI'23 (link).
