The Department of Mathematics welcomed **William Yslas Vélez** as the speaker for the 32nd annual Lonseth Lecture on on Tuesday, May 2, 2017. Prior to his lecture, the department celebrated the achievements of undergraduates, graduates, and faculty with the annual Mathematics awards ceremony. Following the lecture, alumni and faculty joined in judging a graduate student poster competition.

**Lonseth Lecture**

In his lecture, Vélez argued that, too often, undergraduate students rule out further study in mathematics due to self-assessments based on peer interactions, instructor feedback, and their relationship to the material itself, in terms of how competent they feel as well as how passionate. And, at the undergraduate level, subjects like algebra and analysis are often taught as dry, discrete topics with little relevance to each other. Yet beyond the classroom, mathematical research is dynamic and interconnected in a way that more students would find engaging if they were introduced to it early on. Mathematics opens many doors for students and should never be an obstacle to a desired career path.

The Lonseth Lecture was established in 1985 to honor Arvid T. Lonseth, Professor Emeritus and former chair of the Mathematics Department at Oregon State University. Read more about Arvid Lonseth and the Lonseth Lecture series here.
