Professor of Management Science & Healthcare Informatics
Professor Padman's research addresses problems at the interface of healthcare, information technology and management science, particularly healthcare information systems, operational planning and management, and data mining and decision support methods. Her current research in the healthcare domain investigates data mining methods for healthcare decision support; evaluating the use and impact of information technology and systems in healthcare environments, particularly for point-of-care disease management; and, examining tradeoffs between access and confidentiality in large multidimensional public-use and healthcare databases. Her research on these topics has been funded by the National Science Foundation, National Library of Medicine, DARPA, and the Army Research Office.
Prior to joining the Heinz School's faculty in 1989, Professor Padman was Assistant Professor of Management Science in the Carlson School of Management at the University of Minnesota. More recently, she was Visiting Scientist at Humboldt University in Berlin, Germany. She is an Associate Editor with the INFORMS Journal on Computing and a past Associate Editor with Operations Research. She has also served on the National Science Foundation (NSF) panels on Operations Research grants and on several program committees of information systems and operations research conferences.
Professor Padman has received the Emil Limbach Award for Excellence in Teaching and the Outstanding Instructor Award in the Woodrow Wilson Summer Studies program, both at the Heinz School at Carnegie Mellon University. She is also a recipient of the Individual National Research Service Award from the National Library of Medicine, a division of the National Institutes of Health. Professor Padman's paper titled "On Analyzing Interactions in a Software Agent Marketplace" (with Heinz School colleagues) was awarded the best paper award at 2000 Workshop on Information Technologies and Systems in Brisbane, Australia.
