Abstract A Research Experience for Undergraduates (REU) is an extra-curricular opportunity for science or engineering students in the sophomore, junior, or senior year to participate in academic research in much the way graduate students do. It is a way to introduce undergraduates to the excitement of real research. Because it also seems an easy and attractive way to integrate ethics into undergraduate education, working out how professors of engineering or science might actually incorporate professional ethics into an REU seems desirable. This paper describes one effort to do that with engineering students.
