Hi, I’m Rajesh. I’m passionate about Computer Architecture and optimizing systems for Machine Learning. At ARM, I focus on scalability and efficiency of datacenter infrastructure for AI workloads.

With over 7 years of experience in the semiconductor industry, I’ve held roles at AMD Research, Qualcomm and Analog Devices, Inc., working across various levels of abstraction in Computer Architecture. I am well-versed in addressing challenges in parallel computer architecture and optimizing the performance of heterogeneous systems.

I earned my graduate degree from University of Wisconsin-Madison, where I worked with Prof. Matt Sinclair at the Heterogeneous Architectures Lab, on mechanisms to promote data reuse on chiplet-based GPU architectures.
