Mr. PGP Kumara

Prasad graduated from the University of Kelaniya in 2021 with a B.Sc. Honours degree in Mathematics. After graduation, he started his academic career as a Graduate Teaching Assistant at the Department of Mathematics, University of Kelaniya. Later, he joined the Department of Mathematics at the Open University of Sri Lanka (OUSL) as a Temporary Lecturer in Mathematics. He also worked as an Instructor Gr. II at the Department of Mathematics, Faculty of Engineering, General Sir John Kotelawala Defence University. Meanwhile, he served as a Visiting Lecturer at the Ocean University, the Faculty of Engineering at OUSL, and the Information and Communication Technology Centre at the University of Kelaniya. Prasad is currently a Lecturer (Probationary) in Mathematics at the Faculty of Computing, Sabaragamuwa University of Sri Lanka.
