BC at home




Prof. Caldwell conducts research in applying human factors and industrial engineering principles to team performance in complex task environments.  His early research examined the potential social and technological effects of internet multimedia communications, even before the release of the Mosaic browser in 1993.  Prof. Caldwell's discovery of the importance of information delay with increasing bandwidth has been meaningful since the growth of internet file sharing, which demonstrated that delay remains a concern to ensuring satisfactory quality of service.  A central and fundamental component of Prof. Caldwell's work in this area was the application of engineering feedback control models of information freshness, cost of access, and value of information gain.


Prof. Caldwell's research group is known as the Group Performance Environments Research (GROUPER) Laboratory.  The mission of the GROUPER Lab is to be a premier research group in the areas of analysis, design and improvement of how humans work with, and share knowledge through, information and communication technology systems on Earth and in space.  His work, and that of GROUPER, is internationally recognized for integrating social and technical considerations in human task coordination and team performance.  Over 25 of his former graduate students (MS and PhD) have achieved success in academic, government, industry, and military positions.



Primary GROUPER Streams


The primary mission of the PERCH research stream is to improve the efficient and timely availability of information, to enhance the quality and safety of healthcare delivery among healthcare consumers, providers, and services.  Over the past 10 years, Prof. Caldwell's efforts in this research area have generated over $200,000 in principal investigator funding, ongoing participation in the development and activity of the Regenstrief Center for Healthcare Engineering, and lecturing and advising with the Canadian Organisation of Medical Physicists.
