The Math Dept. Brings the School Year to a Close with Awards & Celebration!

The Math Dept. gathered at Poquitos Mexican Restaurant, near the Seattle University campus, for the annual salute to their graduating math majors. Students, faculty, and staff came together for a festive meal and to celebrate the hard work of students who will be moving on to careers, graduate school, and the further exploration of mathematical possibility. As part of this event, Math Chair Dylan Helliwell presented awards to five special students who went above and beyond what was expected of them. Each award was named in recognition of beloved faculty members past. The Janet E. Mills Award for Undergraduate Research in Mathematics was awarded to Suki Shergill. The Mirbagheri-Yandl Award for Achievement in Mathematics was awarded to Arthur Yae. The Wynne Alexander Guy Spirit of the Mathematics Department was awarded to Ranjani Sundaresan, as well as two students who graduated previously, Nancy Mariano and Ariana Mendible. It was decided for the first time this year that this last award could go to students who provided extraordinary service to the Math Department, whether or not they were math majors—therefore the delayed recognition of Nancy and Ariana. We wish all Seattle U.’s graduating seniors well, as they move out into the world to make it a better place.

Undergraduates To Untangle Knot Research

Logo for the Center for Undergraduate Research in Mathematics

With a grant from the Center for Undergraduate Research in Mathematics (CURM), Professor Allison Henrich will lead a team of three undergraduates in knot theory research throughout the 2019-20 academic year. Their research will seek to learn more about knotting complexity by studying unknotting operations on knotted structures. They will also apply their findings to studying topological-combinatorial games.

Dr. André Yandl, was a longtime Seattle University math professor. He passed away February 15, 2019. He was born March 28, 1931 in El-Biar, Algeria, and came to the US in 1949. Despite knowing little English, André enrolled at Wenatchee Junior College, earned his AA degree, then completed his undergraduate and graduate studies in mathematics at the University of Washington.

André taught at SU from 1956 to 1965, then from 1966 until he was granted the title of professor emeritus and retired from full-time teaching in 2001. He continued to teach a few classes at SU until 2011, when he finally retired at 80 years old. During his career, André taught for one year at Western Washington University after earning his Ph.D., one term at a university in India in 1969, and was math department chair at SU from 1966 to 1979.

André wrote 6 textbooks and co-wrote 2 more, plus numerous mathematical papers. He was the recipient of the first ASSU Outstanding Teacher Award in 1981 and received the first award by the PNW section of the MAA for Distinguished College and University Teaching of Mathematics in 1992. For many years he was the faculty advisor for the SU math club and served as faculty representative for the athletic department at SU.

The faculty and advisors in SU’s Mathematics Department are second to none! I am beyond impressed with the passion, care, and enthusiasm that they express inside and outside the classroom. I feel that I’ve received a top-tier education that has established a solid foundation for my future endeavors.
