The College of Natural Sciences annually selects a very small group of graduating seniors -- just one percent of the graduating class -- to sit on the dais with the Dean during Commencement and be recognized as Dean's Honored Graduates. These students must be nominated by their department and are chosen by a College-wide panel of faculty.
The Department of Mathematics is usually very well represented in this group. We regularly graduate over 200 majors annually but in addition to the students we nominate for the DHG recognition, many of our majors are nominated by other departments in which these students are pursuing a second major. These other departments include most of the units in our College --- Physics, Computer Science, Astronomy, etc. (We also have very many strong students pursing second majors in departments outside the College, including Economics, Geology, and even English and History!)
Here are the mathematics majors among the recent Dean's Honored Graduates:
