Personal Research Statement:

My work has largely revolves around the development of knowledge-based systems that provide decision-support for guideline-based medical care. Functionally, such systems assist healthcare providers screen patients who may be eligible for guideline-based care, and assist them in providing care according to the provisions of the guideline. Technically, the goals of my work are (1) to analyze algorithms used in guideline-based therapy, screening, and test-ordering, (2) to represent formally the terms and relations used in guideline-based decision-making, (3) to integrate a reasoning system with external time-oriented database, and (4) to develop ways network-based mechanism for users to interact with such systems. More recently, my work has focused on the development of biomedical ontologies that model drugs, clinical trials, and annotation of research studies.

My work is done as part of the PROTEGE , EON, InterMed, ATHENA, SAGE, and other projects at Stanford. In these projects we are looking at protocols and guidelines in breast cancer care, diabetes, hypertension, and other disease areas. I am looking at component-based approach for creating a guideline modeling and execution architecture. The integrated system will include temporal extensions to the relational database formalism and the ability to make abstractions over temporal intervals.
