    Research Experience


    My research interests are in the field of Storage and Distributed Systems. I got an opportunity to work with some of the finest minds while working as a Graduate Student Researcher for the Exploratory Systems Lab at UC Davis, where I worked on ResilientDB, an open sourced permissioned blockchain. Prof. Mohammad Sadoghi, along with Suyash Gupta and Sajjad Rahnama, helped me guide through my research.
    Research has not only taught me novel concepts, but it has also embarked a sense of discipline and focus which I believe is essential for success.



    Exploratory Systems Lab


    • Graduate Student Researcher

      (January 2020 – Present)


      ResilientDB is an open-sourced permissioned blockchain fabric, which easily allows its users to set up a blockchain application.

      Fault tolerance and scalability are the two major limitations of most distributed systems. In this project, we intend to show that sharding is a prominent solution to these limitations in distributed transaction processing, specifically for permissioned blockchain systems. We would achieve this by implementing a sharding protocol called AHL (Attested HyperLedger) in ResilientDB. AHL makes use of Trusted Execution Environment to improve fault-tolerance and sharding to enhance performance and scalability. ResilientDB is a high-throughput yielding permissioned blockchain system.

      Developed the sharding protocol by enhancing the Practical Byzantine Fault Tolerant protocol by using 2 Phase Commit Protocol. The result dramatically increased the system throughput by 200% to 240k txns/sec

      Technologies: C++, Bash, Python, Google Cloud Platform



    Teaching Experience


    University of California, Davis, is a rich and resourceful university and this is where I took a stab at Academic Teaching. I thoroughly enjoyed my time teaching young minds the concept of programming and it gave me immense pleasure to guide my students in order to shape their future.
