I am a Distinguished Research Staff Member and Master Inventor at IBM Research AI in Yorktown Heights, where I lead the Foundations of AI Reasoning group. I have over 18 years of research experience in knowledge representation and reasoning focused on developing theories, algorithms, standards, and systems for scaling reasoning over large and expressive knowledge bases that tolerate inconsistencies and uncertainties inherent in KBs populated from unstructured sources. I have led various research efforts on applying machine learning and knowledge representation and reasoning in many domains. I am a co-editor of the OWL 2 Web Ontology Language Profiles specification, and have authored or co-authored over 100+ scientific reports and manuscripts that have been cited, in aggregate, more than 3500 times.
