Siddharth Gupta

Senior Researcher at Huawei, Zurich

Hello!

I am currently a Senior Researcher at Huawei Technologies in Zurich.

I have recently finished my Ph.D. from the School of Computer and Communication Sciences (IC) at École Polytechnique Fédérale de Lausanne (EPFL). I was advised by Prof. Babak Falsafi and Prof. Abhishek Bhattacharjee.

I am broadly interested in the field of systems and cross-stack research problems found in modern, large-scale datacenters. My research focuses on designing high-performance and cost-effective TB-scale memory hierarchies for datacenter servers.

Intel funded a multi-PI project based on Midgard (Announcement).
I am one of the recipients of the Qualcomm Innovation Fellowship 2021 (Announcement, EPFL).

You can find my CV (updated March 2025) here.
