About Me

I am a Masters student in the Computer Science Department of Stony Brook University. I am interested in systems research and prior to joining Stony Brook University, I was working in systems and storage domain for 4 years. I am doing my advanced project under the guidance of Prof. Erez Zadok in File Systems and Storage Lab (FSL).

Marvell Semiconductors Inc., Storage R&D
Associate Software Engineer, July 2012 - January 2014

DragonFly - PCIe based caching solution
Host Storage Stack
• Proposed a design for platform independent CLI, implemented and handled ownership of the same
• Worked on entire Host Storage Stack - user space to kernel (Linux) while implementing commands to configure and manage PCIe based caching card
• Implemented timer based process monitoring mechanism in shell script

Windows Specific
• Ported the user space management stack to Windows
• Worked on Block Filter driver to export I/O statistics to PerfMon through Kernel Mode Performance Counters
• Developed system report using PowerShell
• Enhanced Windows Service

Academic Projects

• RISC-V Processor
  Developed a scalar, in-order, 6 stage pipelined processor core with direct mapped caches for the RV64IM ISA in SystemVerilog.
• Extending OpenSHMEM Memory Model to support heterogeneous memory
  Enhanced OpenSHMEM PGAS model to support multiple symmetric heaps, multiple memory registrations for RDMA, and different kinds of memory using Sandia OpenSHMEM and Memkind library.
• Ergonomics Monitor
  Developed a wearable device that monitors user's posture using Arduino and flex sensor, and provides feedbacks through 3D fabricated wrist band with LEDs to rectify the posture.
• E-- compiler
  Developed a compiler for the E-- language using flex, bison and C++.
• Mergesort system call
  Developed a Linux kernel module to support a new system call which merge sorts input files and writes sorted records to output file.
• Trfs (stackable file system with operation-tracing support)
  Developed a new file system - trfs to capture records of file system activity. These records are written to a file on disk which is later used by a user-land program to replay the traced operations.
• Linux kernel-based system to support per process system call vectors
  Modified Linux kernel and developed new system call vector modules to support system calls on a per process basis.
