Dr Nirodha Weeraratne

Agricultural microbiology

Gulbali Institute


Nirodha is an agricultural scientist conducting research and teaching in agricultural biology, soil science, and crop protection. Her research involves harnessing soil-plant-microbial interactions for sustainable management of agroecosystems. She is currently working on developing new resources to enhance sustainable agricultural production systems through pest and pathogen management, and improvement of soil health and fertility. She is also exploring the use of marine macroalgae for developing agrochemicals, nutraceuticals, and cosmetics.
