The recognition was based on results from the Center for Instructional Excellence’s teacher evaluation surveys. Instructors were evaluated on six questions measuring teaching effectiveness on a five-point scale. Eligible courses included undergraduate and graduate engineering courses with at least 10 students and a response rate of 50% or higher.

For the spring 2026 semester, instructors whose evaluation scores ranked at or above the 75th percentile were recognized across four course-size categories: small, medium, large and very large.

Chatzidakis’ recognition highlights the strong marks he received from students and his commitment to excellence in nuclear engineering education.
