I'm a researcher in the Center for Biomedical Informatics Research (BMIR) at Stanford University. I work on methods and tools (such as the Protégé ontology editor) for building, comparing, versioning, and reasoning over knowledge bases primarily represented as OWL ontologies. More recently, as part of the Center for Expanded Data Annotation and Retrieval (CEDAR) project, I've been investigating methods to analyze and to automatically clean scientific metadata in online repositories.

My research interests revolve around knowledge representation and reasoning, deep learning, software and ontology engineering, and Semantic Web technologies.

I graduated with a Ph.D. from The University of Manchester, in the Information Management Group of the School of Computer Science, under the supervision of Uli Sattler and Bijan Parsia. My main hobbies are scuba diving (I'm an Open Water Scuba Instructor), sailing, surfing, and more recently skiing.
