Prof. (Mrs.) Maheshi B. Dissanayake received the B.Sc. Engineering degree with First Class Honours in Electrical and Electronic Engineering from the University of Peradeniya, Sri Lanka, in 2006, and the Ph.D. in Electronic Engineering from the University of Surrey, United Kingdom in 2010. Since 2021, she has been a professor in electrical and electronic engineering at the Department of Electrical and Electronic Engineering, Faculty of Engineering, University of Peradeniya. From 2013 to 2021, she was a Senior Lecturer at the Department of Electrical and Electronic Engineering, Faculty of Engineering, University of Peradeniya. Also, she has been a visiting research fellow at King's College London from 2015-2017. Her research interests include error correction codes, robust video communication, molecular communication, machine learning in communication networks, deep Learning for video/image analysis, and biomedical image/clinical data analysis. Prof. Dissanayake is a Senior Member of the Institute of Electrical and Electronics Engineers (IEEE) and an Associate member of the Institution of Engineers, Sri Lanka (IESL). She has served as an organizing committee member and TPC Member of many IEEE conferences, and as a reviewer in IEEE journals in the area of molecular communication and image processing. Furthermore, she served as the first female chairperson of IEEE Sri Lanka Section for the year 2021/22, and she was the founder as well as the past Chair of IEEE Women in Engineering Sri Lanka section for the years 2015/16, 2016/17 and 2020/21.
