Dr. Liang Zhao

About Me

I am Winship Distinguished Research Professor of Computer Science at Emory University and a member of the Cell & Molecular Biology Division at Winship Cancer Institute. My research develops scalable and trustworthy machine learning for structured, spatial, and scientific domains, with major contributions in graph neural networks, geospatial and spatio-temporal reasoning, scientific ML, retrieval-augmented and reasoning-oriented LLMs, robust agentic systems, uncertainty quantification, and optimization for energy and infrastructure. I received my Ph.D. in Computer Science from Virginia Tech in 2017 as an Outstanding Doctoral Student. I have authored 200+ papers in leading venues including KDD, NeurIPS, ICLR, AAAI, and IJCAI. My work has been supported by NSF, NIH, and major industry partners including Amazon, Meta, Merck, NVIDIA, Cisco, NEC Labs, Oracle, Sony, and Bank of America. My work has been recognized by national and international institutions, including the NSF CAREER Award and the IEEE Middle Career Award, and has received sustained best-paper recognition across premier AI and data science venues. These honors include, test-of-time award, best-paper award or runner-up awards at KDD 2025, ICDM 2022, ICDM 2019, CIKM 2025, WWW 2021, and SIGSPATIAL 2022, reflecting both the immediate impact and long-term influence of my research across machine learning, graph AI, spatial intelligence, and scientific applications.
