Nadesh Ramanathan

I am a Research Associate in the Circuits and Systems Group at Imperial College London's Department of Electrical and Electronic Engineering, where I completed my PhD under the supevision of Professor George A. Constantinides and Dr. John Wickerson. My PhD was funded by the EPSRC Centre for Doctoral Training in High Performance Embedded and Distributed Systems (HiPEDS). Prior to my PhD, I graduated with an MPhil in Advanced Computer Science at University of Cambridge.

I am mostly interested in designing digital circuits on field-programmable gate arrays (FPGAs). I am particularly interested in the efficiency of high-level synthesis (HLS), a process in which software is automatically mapped to bespoke hardware. In my PhD, I explore the efficiency of high-level synthesis for multi-threaded C programs.
