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.

Projects

• 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.
