Sharada Navada
About
I am an Associate Professor in the Department of Biotechnology and Food Science at NTNU. My research focus is water treatment in recirculating aquaculture systems (RAS). This encompasses physicochemical and microbiological water quality and management in RAS.
I have nearly 10 years of work experience (including an Industrial PhD) as a process engineer in the water treatment industry, especially in RAS. I also completed an Industrial PhD, where I developed salinity acclimation strategies for bioreactors in RAS for Atlantic salmon. I investigated the nitrification process in biofilms under varying salinities, from freshwater to seawater. I also studied the impact of salinity on microbial communities in the biofilm and how microbial strategies may be utilized to improve bioreactor management.
