The 33rd Annual Lonseth Lecture took place Thursday, May 3, 2018 in the Learning Innovation Center. This year's lecture was a big success due to the attendance of mathematics students, faculty, and guest speaker Dr. Henri Berestycki. The lecture began with an award ceremony recognizing achievements by undergraduate and graduate students in the mathematics departments. The awards were followed by guest speaker, Professor Henri Berestycki, from Ecole des Hautes Etudes en Sciences Sociales (EHESS) in Paris, France.

In his lecture, Berestycki, talks about the classical Lotka-Volterra model which describes predator-prey interactions, and why it's one of the cornerstones of mathematical ecology. His presentation included an extension of the original Lotka-Volterra system that shows how territories are formed as a result of strong competition between packs of predators.

### History

The Lonseth Lecture has been an ongoing tradition in the Mathematics Department. It was established in 1985 to honor Arvid T. Lonseth, Professor Emeritus and former chair of the Mathematics Department at Oregon State University (Arvid Lonseth and the Lonseth Lecture series).

### Department of Mathematics Awards

The Department of Mathematics awards ceremony gives acknowledgement to undergraduate and graduate students who demonstrate outstanding work and dedication, and the graduate faculty award recognizes excellence in teaching.
