Engineering Lecturer Builds Class Character with Frequent Message

When Carissa Roper BS’12, MS‘13 walked into a class taught by Dr. Randall Lehmann, a senior lecturer in the Erik Jonsson School of Engineering and Computer Science, she was greeted not by a mathematical formula, but with the word “character” written across the board. 

“He then explained that we were all intelligent and capable, but our character is how we would really affect the world,” she said. “In his mind, it was important not only to instruct us on radio frequency (RF) engineering, but to help us develop a strong moral fiber so that we could be conscientious members of the community.”
For his efforts, Lehmann is a recipient of a 2014 Regents’ Outstanding Teaching Award.
