Research/Professional Interests:

Modeling of biomedical ontologies and clinical guidelines and protocols, development of knowledge-based systems, knowledge representation, databases, temporal database and temporal reasoning, protocol-based health care

Personal Research Statement:

Trained in computer science (with specialization in artificial intelligence), my research revolves around the representation of biomedical knowledge and the development of computational methods to apply such knowledge to solve biomedical problems. Over the years I have successfully worked with clinicians to elicit and to represent and make computable clinical protocols and guidelines and medical terminologies. Technically, I focus on (1) the formal representation of and reasoning on biomedical concepts in ontologies, and (2) the development of algorithms to apply such representation in query systems and clinical decision support. I had worked on projects that use such models to drive protocol-based decision support and on projects where I developed novel representations for autism, clinical research, and ICD-11 concepts.

My work is done as part of the PROTEGE , ATHENA and other projects at Stanford and elsewhere. In these projects we are looking at ontology development, meta-data representation, and protocols and guidelines in breast cancer care, diabetes, hypertension, and other disease areas.
