Suren Sritharan

I am a research assistant at the Sri Lanka Technological Campus, where I work on computer vision-related research. I am also volunteering at the University of Peradeniya: COVID Research Group which focuses on combatting the issues caused by the pandemic, through AI and computer vision. I recently graduated from the University of Peradeniya with a B.Sc specializing in Computer Engineering. Apart from research, I am also interested in competitive programming, and I love travelling.

Throughout my undergraduate studies, I was fortunate to be advised by many fantastic researchers. Most recently, I have been working with Prof. Janaka Ekanayake and Prof. Samath Dharmaratne on the potential of AI for COVID-19 related applications. Previously, for my final year research project, I worked with Prof. Roshan Ragel, Dr. Roshan Godaliyadda, Dr. Parakrama Ekanayake, and Dr. Vijitha Herath on image quality enhancement under low/high exposure conditions. During my internship at Nokia Bell Labs, I had the privilege of working with Prof. Haris Gačanin. I have been collaborating remotely since, and I completed a project on the application of machine learning models for dynamic wireless networks.

I'm interested in machine learning, computer vision, and their application in other domains. Most of my current research focuses on image quality enhancement, in the presence of varying illumination and noise. Besides, I am also working on a cross-domain research in the intersection of computer vision and community medicine which focuses on quantifying the risk associated with congested areas during pandemics. Before that, I was involved in an application-oriented machine learning research for wireless communication. I have explored a broad area of research topics around machine learning and vision during my undergraduate period, and some of my publications are mentioned below.
