About Me

Hello! I am a 5th PhD student (circa August 2021) in the Computer Science Department (CSD) at Carnegie Mellon University (School of Computer Science) advised by George Amvrosiadis (in PDL).

In the past, I worked with Don Porter at OSCAR lab on Virtual Memory (page table and TLB research using novel hashing techniques: Mosaic Pages) and File Systems (BetrFS). I'm still very much interested in novel Virtual Memory techiniques, but my broader research interests lies in all things OS.

Presently, I am exploring heterogeneous replication in datacenters for parquet and parquet-like file, to enable performance and I/O wins for different applications with different access patterns. Previously, I worked on computational storage at CMU and Samsung and created an emulator and sample workloads for such devices.
