about me

I am an assistant professor at the Department of Computer Science and Engineering, University of North Texas. I have two broad research interests: 1. Explaining the behavior and limitations of LLMs with a focus on model bias and reasoning abilities; and 2. Scholarly information processing to enhance users’ experience with digital libraries. Some example tasks are a) extracting information from scientific figures, b) understanding reproducibility of scientific articiles, and automatically generating limitations of scientific papers.

Experience

Previously, I was an NLP Scientist at the National Board of Medical Examiners. Before that, I worked at the University of Michigan Medical School on information extraction models on clinical text and their generalization abilities + models for early dementia prediction. I came to Michigan from the Department of Computer Science, UCPH, CopeNLU group, where I worked on the explainability of DNN models used in multi-hop reasoning systems, such as question answering, fact-checking and natural language inference.

During my Ph.D. from Penn State I worked in the CiteSeerX group on information extraction from scholarly figures and tables, information retrieval and crawling. Post Ph.D, I worked as an NLP/ML engineer at Interactions. I developed DNN models for large scale entity extraction and linking, dialog systems, and sentiment classification. I also contributed to a DNN library that was used as the ML backend for the company.
