Alex Mathai is a Columbia CS PhD student and former IBM Research engineer with nine years of experience applying machine learning and deep learning to real-world software and networking problems. He builds LLM-driven agents to debug million-line system codebases like the Linux kernel and previously designed knowledge-graph and graph-neural-network approaches to modernize monolithic mainframe applications into cloud-ready microservices. His work spans AI robustness (exposing and mitigating NLP model failures), encrypted traffic classification at ISP scale, and satellite image segmentation using U-Net, demonstrating an unusual blend of systems-scale engineering and applied ML research. Based in New York, he combines rigorous academic training and top-tier industry impact, with a knack for translating complex legacy systems into practical, data-driven solutions.
