Shubham Kaushik

Graduate Student, Researcher


Hello! 👋 I’m a PhD student at the Michtom School of Computer Science, Brandeis University, working under the mentorship of Prof. Subhadeep Sarkar. My research revolves around optimizing data systems and distributed systems, with a current focus on Log-Structured Merge (LSM) trees. In this domain, I explore innovative compaction strategies and improvements to range deletes. I completed a Master’s degree in Computer Science, specializing in Data-Centric Computing, at the Graduate School of Arts & Science, Boston University.

Professionally, I have been involved in various capacities across the tech industry, from innovative gaming startups like Kwalee to major corporations such as FIS Global and Wipro Limited. My roles have predominantly centered around data systems and distributed systems, where I developed skills that are integral to both my research and industry applications.
