I joined the University of Arizona School of Information in August 2016, after three years as an assistant professor in Computer and Information Science at the University of Alabama at Birmingham. I previously worked as a postdoctoral researcher at Stanford University's Natural Language Processing group, Johns Hopkins University's Human Language Technology Center of Excellence, KULeuven's Language Intelligence and Information Retrieval group in Belgium, and the University of Colorado's Center for Language and Education Research.
My research interests include natural language processing and machine learning theory and applications, including modeling the language of time and timelines, clinical language processing, machine learning for information extraction, and language processing for personalized learning tools. There is a large community at the University of Arizona pursuing similar natural language processing research. Visit us at: http://nlp.arizona.edu/.
My ongoing funded projects include:
- NIH NLM 2R01LM010090, Temporal Relation Discovery for Clinical Text, in which we are designing machine learning algorithms to extract timelines from clinical text and integrate those with structured data from the electronic medical record.
- NIH NIGMS 1R01GM114355, Extended Methods and Software Development for Health NLP, in which we are designing machine learning algorithms that leverage large collections of text to improve information extraction tasks such as mapping text to ontologies and discovering links between health events.
- DARPA W911NF-18-1-0014, Global Reading and Assembly for Semantic, Probabilistic World Models, in which we are designing machine learning algorithms to infer from text the times and locations over which a causal relation is valid, with the goal of modeling complex interactions in domains like food security.
