# Chelluri Lecture Series

The Chelluri Lecture series is offered in memory of **Thyagaraju (Raju) Chelluri**, who graduated magna cum laude from Cornell with a Bachelor's degree in mathematics in 1999. Raju was a brilliant student, a gifted scholar, and a wonderful human being who died on August 21, 2004 at the age of 26, shortly after completing all requirements for the Ph.D. in Mathematics at Rutgers University. He wrote a thesis called *Equidistribution of the Roots of Quadratic Congruences* under the supervision of H. Iwaniec and was awarded a Ph.D. posthumously.

The Chelluri Lecture Endowment was established in 2004 with support from family and friends of Thyagaraju (Raju) Chelluri. Each year, a distinguished mathematician will be invited to give the Chelluri Lecture.

### Upcoming Lectures

**Daniel Wise**, McGill University

Thursday, April 20, 2017 - 4:30 PM - 251 Malott Hall*The Cubical Route to Understanding Groups*

Cube complexes have come to play an increasingly central role within geometric group theory, as their connection to right-angled Artin groups provides a powerful combinatorial bridge between geometry and algebra. This talk will introduce nonpositively curved cube complexes, and then describe the developments that recently culminated in the resolution of the virtual Haken conjecture for 3-manifolds, and simultaneously dramatically extended our understanding of many infinite groups.

Following the lecture, a musical performance and reception will be held at A. D. White House.

If you need accommodations to participate in this event, please contact Heather Peterson.
