Research
At OUNLP, we explore the frontier of natural language processing and machine learning with the goal of building intelligent, trustworthy, and practical AI systems. Our work spans multi-party, multi-modal dialogue and discourse analysis (in domains like education and mental health), agentic models and domain-specific “world” models for human-AI teaming, efficient structured-prediction and symbolic methods to augment neural networks, and the robust deployment and evaluation of trustworthy AI.
