Research Interests: Neural Entity Linking, Clinical Information Extraction, Question Answering, Natural Language Processing, Deep Learning
I did my PhD at the Natural Language Processing Lab in the School of Computing Science at Simon Fraser University in Vancouver, Canada. My research uses pre-trained language models and structured prediction based fine-tuning methods. My published work includes using structured prediction to extract linguistically useful representation learning from pre-trained models for neural machine translation, work on policy generation for simultaneous neural machine translation, novel pre-training, fine-tuning and structured prediction inference for entity linking to ontologies like Wikipedia, analyzing the strengths and weaknesses of recent entity linking methods without relying on hand-crafted candidate sets, and information extraction, specifically entity linking, as an alternative to retrieval-augmented generation methods, for enhancing large language models for question answering.
