Clairvoyance Management Team

The Clairvoyance Corporation management team is made up of a dynamic group of innovators, leaders and technology entrepreneurs from the scientific and business arenas:


Dr. David A. EvansDr. David A. Evans, President, CEO, and Chief Scientist

Dr. David A. Evans co-founded Clairvoyance Corporation in September 1992. Between 1992 and August 1996, he served as the company's chairman and chief scientist, and led the product development and marketing efforts of the company. He joined the Clairvoyance staff full-time as its president, CEO and chief scientist in 1996.

Dr. Evans is responsible for formulating Clairvoyance's corporate strategy, business relations, and new technology and product directions. He is also the director of Clairvoyance research activities and takes the lead in the development of new intellectual property.

Dr. Evans received his Ph.D. in Computational Linguistics from Stanford University in 1982. He joined the faculty of Carnegie Mellon University in 1983, where he established the Computational Linguistics Program (in 1985) and the Laboratory for Computational Linguistics (in 1986), both of which he directed until 1996. As a professor with appointments in the Departments of Philosophy and Computer Science, he brought an interdisciplinary perspective to his work in natural-language processing and information science. In particular, his development of the CLARIT system, beginning in 1988, realized a fusion of ideas from artificial intelligence, NLP and mathematics. The resulting CLARIT technology addressed the problem of using language analysis to support such diverse functions as automatic text indexing, retrieval, filtering, categorization, summarization, extraction, and clustering -- all with a single core process.

At Clairvoyance, Dr. Evans has led the Company's development of advanced technology for information management, which has set standards for precision and versatility. He regards his latest work, focusing on an approach to text mining that goes "beyond Search" directly to the problem of decision support, as the ultimate challenge for information processing.

Dr. Evans has authored three books and over one hundred refereed papers and technical reports. During his years at Carnegie Mellon University, Dr. Evans was the principal or co-principal investigator on 33 funded research projects, encompassing such areas of research as automating foreign-language instruction (the ALICE Project, including ALICE-chan, a module focusing on Japanese); modeling medical decision making and medical expertise (the Macy Project); biomedical knowledge base development for text analysis and indexing (the MedSORT Projects); and creation of an electronic archive for congressional papers (the HELIOS Project); as well as the CLARIT work.

Dr. Evans holds nine U.S. patents on techniques and algorithms related to information processing. A number of additional patents are pending in Japan.

Dr. Evans was recently elected Fellow, American College of Medical Informatics.
