About Me

Hello! I am a 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.

Currently, I am exploring the world of computational storage (CS), and am interested in providing a benchmarking, testing and prototyping standard for research in this community - in the form of a Computational Storage Emulator. I am also exploring offloading File System agnostic applications, such as compression and dedup, to CSDs (Computational Storage Devices).
