I am a Lecturer(Assistant Professor) in Computer Science in the School of Informatics at the University of Edinburgh. I am a member of the ICSA – Institute for Computing Systems Architecture institute. Previously, I was a postdoctoral researcher and Associate Lecturer at the University of Wisconsin–Madison. I earned my Ph.D. working with Prof. Andrea Arpaci-Dusseau and Prof. Remzi Arpaci-Dusseau at the University of Wisconsin–Madison. Prior to graduate school, I worked at NetApp for almost eight years building the WAFL (Write Anywhere File Layout) filesystem. I also spent time (8 months) at SanDisk trying to design the FTL for a TLC drive.
I am a Systems researcher and interested in building systems. My work spans several areas: Concurrency, Operating Systems, Security, Storage & File Systems, and Distributed Systems. In my dissertation, I introduced two new problems – scheduler subversion and adversarial synchronization and broke the decades-old basic assumption that synchronization is a cooperative entity. Instead, I show that synchronization needs to be viewed as a competitive entity to ensure strong performance isolation. I am interested in studying real-world isolation-related problems that arise in concurrent systems due to sharing of resources. My vision is to build abstractions and techniques that provide near-ideal isolation in a shared environment.
I am looking for Ph.D. students to join my group. If you are interested in working with me, please get in touch with me, and see the Informatics Postgraduate pages for information about our postgraduate program and the application procedure. If you are already a student at the University of Edinburgh (Ph.D./MS/MPhil) looking for research opportunities, please schedule a meeting with me.

NOTE: I have decided to refrain myself from highlighting the best paper awards. For me, everyone's work is important (and therefore the best) to ensure that Science makes forward progress.
Teaching
I will be teaching Security Engineering (with Ross Anderson) in Spring 2023. Please enroll if you are interested in Security and Systems. Other courses that I have taught are:
