Research overview

My research is in machine learning/data mining and natural language processing, with an emphasis on applications in health informatics.

For example, one of my core ongoing research aims concerns optimizing the processes of evidence-based medicine using novel natural language processing and machine learning methods. The aim is to reduce the (human) workload involved in conducting systematic reviews, so that we can realize the aim of evidence-based care in an era of information overload.

More broadly, I am interested in core machine learning/natural language processing issues: e.g., structured and unstructured classification techniques; semi-supervised learning methods; learning from imbalanced data; and learning from alternative forms of supervision. Finally, I have recently been involved with projects that involve statistical models for novel problems in NLP, including narrative and sociolinguistic structures.

Support

My work has been supported with grants from the National Institutes of Health, National Science Foundation, the Army Research Office, Seton hospital, Amazon and seed funds from Brown University.
