A Conversation with Dr. Seneviratne

Tell us about a project you are currently working on or recently completed.

Recently, I have been collaborating with a mathematician from the Nanyang Technological University in Singapore to study quantum error-correcting codes obtained from a class of graphs known as meta-circulant graphs. We were able to find several new quantum codes for the first time. This research is ongoing.

What would you tell a student who is thinking about attending A&M-Commerce?

You will have a great college experience. We have small class sizes, and students get individual attention. The faculty at A&M-Commerce are dedicated and care about students both in the classroom and outside. There are various research opportunities for students.

What draws you to your discipline?

Mathematics is both challenging and enjoyable at the same time. My area of research is in coding theory, which is an interdisciplinary subject that connects mathematics with communications engineering and computer science. This is a subject area where pure math concepts are applied in real-world applications.

What has been your favorite course to teach?

There is no one particular favorite class. I like to teach any class in the curriculum from first-year math to graduate classes. I have taught MATH 2318: Linear Algebra most often.
