Stefan Abi-Karam

I am a PhD student at Georgia Tech in the School of Electrical and Computer Engineering under my advisor Prof. Cong (Callie) Hao as part of Sharc Lab.

My main research area is in the intersection of hardware acceleration and applied deep learning as well a mix of other topics, including electronic design automation (EDA), FPGA architecture, VLSI algorithms, non-linear optimization, and high-level synthesis (HLS).

I am also a research faculty at Georgia Tech through Georgia Tech Research Institute (GTRI) within the Cybersecurity, Information, Communication, Command and Control and Software Systems (CIPHER) lab division.

I got the opportunity to attend the DAC 2023 conference for the first time in San Francisco, CA, where I participated in the SIGDA University Demonstration event. I presented a live FPGA demo running on the Xilinx ZCU102 board for our INR-Arch work. It was also my first visiting San Francisco! I also got to meet up for dinner with our former lab mate, Akshay Karkal Kamath, who now works at Apple, as well as Rishov and Hanqiu, who are interning in the Bay Area over the summer.

I started my Ph.D. as a continuation of my Master's work under Prof. Callie Hao at Georgia Tech. Business as usual!

[2023-01-01]
I completed my Master's degree in Electrical and Computer Engineering at Georgia Tech and walked in the 2022 commencement ceremony! My Master's thesis was an inital version of my "GNNBuilder" work under Prof. Callie Hao.

I presented GNNBuilder as part of the 1st Workshop on Democratizing Domain-Specific Accelerators (WDDSA 2022) as part of the MICRO 2022 conference in Chicago, IL. This was my first time attending MICRO and visitng Chicago!

Graph Neural Network Accelerators
Building FPGA accelerators for graph neural networks (GNNs) using HLS. Also building an automated framework to translate PyTorch models to GNN accelerators.
Graph Neural Networks for Electonic Design Automation and Hardware Security
Using GNNs to better representations of digital hardware netlists. Also using these representations to build EDA and HOST tools for hardware designers. Currently exploring self-supervised learning and multi-task learning for this problem.
