Overview

Sirani M. Perera graduated with aB.Sc. (First Class Honors) degreein Mathematics from theUniversity of Sri Jayewardenepura, Sri Lanka, in 2004. She becamethe first Sri Lankanundergraduate in mathematicsto be selected by theCenter for Mathematical Sciences at the University of Cambridge, UK, and receivedafull scholarshipfrom the Cambridge Commonwealth Trust. In 2006, she graduated witha Master of Advanced Studies (the Part III Tripos) in Mathematics (with Honors)at theUniversity of Cambridge, UK, and earned aPh.D. in Mathematicsfrom theUniversity of Connecticutin 2012. She will be a fullProfessor of Mathematics at ݮƵ starting in the fall of 2026.

Dr. Perera was awarded theILAS Olga Taussky and John Todd Prizefor outstanding mid-career achievement by theInternational Linear Algebra Society (ILAS)in 2026.
