About me

Currently I am a postgraduate researcher in the Computer Architecture research group of the University of Cambridge, under the supervision of Dr. Robert Mullins.

Previously I finished a research internship at the Max Planck Institute for Software-System, working in the field of Real-Time Systems after graduating from Delft University of Technology in the area of GPGPU.

My area of interest spans the intersection of architecture and systems, ranging from understanding of the hardware details of computational devices like GPUs to understanding and desiging hardware support for operating systems. With a background in parallel systems I am particularly motivated in understanding the different architectures in the GPGPU space.
