The biggest contribution Kreifeldt made to Tufts was the founding and directing of the undergraduate program in Engineering Psychology. This program broke new ground in a number of ways. It was the first and the only undergraduate program in the country dealing with ergonomics and human factors engineering. It was also the first program at Tufts that permitted students enroll in either the College of Engineering or the College of Liberal Arts. Hundreds of students have attended this unique program and gone on to related careers in the industry, government, and academia.

Research Interests: 

Kreifeldt’s research was extensive and varied. He worked on the problem of collision avoidance in the machines used in cancer radiation therapy and then extended these concepts to work with NASA on the problems of aircraft traffic control. His work on the latter problem in the nineteen seventies has recently been cited as the basis for the next generation of air traffic control systems.

Kreifeldt also worked on problems in automated analysis of microscopy slides for pathological conditions. Some of the ideas generated there, as well as his work with multidimensional scaling, led to a new approach to image analysis.
