I am an Assistant Professor of Computer
Science at Stony Brook University. I co-direct the
Computer Architecture Stony Brook (COMPAS) Lab. Prior to joining
Stony Brook, I completed my Ph.D. at Carnegie Mellon University
(CMU) under the
supervision of Babak Falsafi. While completing my
dissertation, I spent several years working remotely from Ecole
Polytechnique Fédérale de Lausanne (EPFL).
My research interests are in the area of computer
architecture, with emphasis on the design of server systems. I
work on the entire computing stack, from server software and
operating systems, to networks and processor microarchitecture.
My current research projects include FPGA accelerator integration
into server environments (e.g., Intel HARP, Microsoft Catapult,
and Amazon F1), FPGA programmability (e.g., virtual memory and
high-level synthesis), accelerators for machine learning (e.g.,
convolutional neural networks), efficient network processing and
software-defined networking, speculative performance and
energy-enhancing techniques for high-performance processors, and
programming models and mechanisms for emerging memory
technologies (e.g., HBM and 3D XPoint).
If you are a PhD student at Stony Brook and want to work
with me, please send me email to
arrange an appointment.

Computer architecture, with particular emphasis on the design of efficient server systems.
Most recently, my main focus has been on Machine Learning Accelerators, developing hardware techniques to enable fast and efficient implementations of deep learning, and making FPGA-based accelerators more practical and easier to program.
More broadly, my work seeks to understand the fundamental properties and interactions of application software, operating systems, networks, processor microarchitecture, and datacenter dynamics, to enable software and hardware co-design of high-performance, power-efficient, and compact servers.
