I am a PostDoc Researcher in the Department of Computer Science at Purdue University. I work in FRIENDS and PurSec labs under the guidance of Prof. Dongyan Xu and Prof. Dave (Jing) Tian, where i also completed my PhD. Other than that I also work closely with Prof. Antonio Bianchi. My research interest lies in the area of systems and security. In particular, I am interested in identifying novel architectures and security issues in confidential computing and operating systems.
Working on embedded systems security and program analysis technologies.
Worked on enhahcing Qualcomm's Trusted Execution Environment (TEE) OS (QSEE/QTEE)
Worked on design and rework of Nucleus RTOS for Industry 4.0.
Worked on the design and development of Mentor Embedded Hypervisor.
Developed POC for various systems mostly inclined to concentrated solar energy such as heliostats, parabolic troughs and fresnels.

Pieces is a highly programmable language-agnostic automatic program compartmentalization framework. Pieces can be programmed to partition programs based on various criteria, including methods of isolation between compartments.
Security Enhahnced FreeRTOS (SeRTOS) is a security enhahnced version of the famous RTOS, FreeRTOS. It has compile time privilege separation and other cool security features.
Organized the security reading group at Purdue and managed research logistics for PURSEC.
Organized various activities for the graduate student association and computer science department.
Part of the Ombuds Services program at Purdue Graduate School.
Part of the Diversity Task Force at Purdue CS.
Part of the faculty search/recruitment process at Purdue CS.
Apart from being a security researcher, i like to travel and hike. I've visited most of Northeren Pakistan and various places around the US. When forced indoors, I like to play games (I have achieved ELO of 1700+ on Age Of Empires using unconventional methods), learn new instruments and play with synthesizers. Here's some music i've written over the years.
