Background and activities

I am pursuing an Industrial PhD in collaboration with Krüger Kaldnes (Veolia Water Technologies, Norway), Nofima AS, and NTNU. My project is a part of CtrlAQUA SFI; an international project to develop technological and biological solutions for closed-containment systems for Atlantic salmon farming. 

About me: I completed my B.Tech degree in Chemical Engineering at the Indian Institute of Technology, Bombay. Thereafter, I moved to the USA to get my M.Sc. in Environmental Engineering at Carnegie Mellon University, where I studied water chemistry and water treatment. After my studies, I joined Veolia Water Technologies (VWT) USA where I worked for three years on industrial wastewater treatment, before moving to VWT Norway. Here, I was offered the opportunity to do an Industry PhD on the water treatment challenges faced in land-based farming of Atlantic salmon.    

My research goal is to develop strategies for managing the biological water treatment system in recirculating aquaculture systems (RAS). In particular, I focus on the nitrification process in biofilms under varying salinities, from freshwater to seawater. I am also studying the impact of salinity on biofilm microbial communities and how microbial strategies may be utilized to improve bioreactor design and management. With every new day of research, I am falling deeper in love with these fascinating creatures.
