About Me
I am currently a senior research scientist at NEC Laboratories America. Previously, I served as a research assistant professor in the Department of Electrical Engineering & Computer Science at Northwestern University, where I also completed a one-year postdoctoral fellowship under the supervision of Prof. Alok Choudhary. I received my Ph.D. degree from the Computer Science Department at North Carolina State University.
My research aims to advance real-world applications and systems through enhanced intelligence, increased security, and more effective decision-making capabilities. I have been primarily working on graph mining, anomaly detection, causal AI, AI security, graph neural networks, text mining, and their applications in computer security, IoT/OT systems, climate science, social media analytics, material science, bioinformatics, and finance, enabling machines to better understand real-world complex dynamic systems.
I have published over 80 peer-reviewed research papers in major academic venues such as CVPR, NeurIPS, KDD, ICLR, AAAI, WWW, and IJCAI. My work has been featured in various news media including NSF News, DOE ASCR Discovery, NHK TV News, The Conversation, and esciencenews. Additionally, my research has led to the filing of over 100 patents, with 40 already issued.
