I completed my PhD from Department of Computer Science, School of Computing and Information, University of Pittsburgh under the guidance of Dr. Rami Melhem (co-advised by Dr. Jun Yang). My dissertation was focused on designing adaptive memory management techniques for discrete CPU-GPU heterogeneous memory systems, including commodity cloud infrastructures and exascale systems. I have proposed a set of software-hardware co-operative solutions that leverage existing hardware advancements and software-managed unified memory runtime to relieve programmers from the burden of explicit memory management and to mitigate performance variability in consolidated heterogeneous systems.

My research interests are, broadly, computer architecture, heterogeneous systems, distributed computing, operating systems, and run-times. However, I am interested in studying many of the system-wide challenges, like QoS resiliency, fault-tolerance, encountered when building software for large-scale distributed systems.

I have started working as a Software and Hardware Modeling Engineer (ICT3) in Apple, Cupertino (IMG SW - GPU SW - Silicon Development Team) from November 2020.
