Background and activities

I am a PhD Candidate in the department of Chemical Engineering, NTNU under supervision of Ass. Prof. Johannes Jäschke and co-supervisor Prof. Sigurd Skogestad. My PhD project is titled "Estimation of unmeasured variables in subsea systems" and is a sub project under the SUBPRO center for research (a.k.a Subsea production and processing). My project includes developing simplified control-oriented process models for separators (such as, gravity separators, and cyclonic separators: deoilers and dewateres) and flow meters that are used in subsea oil and gas production and processing. These models will facilitate estimation of variables, such as separation efficiency, droplet sizes, flow rates etc. that are not directly measured in subsea systems. The state estimation methods likely to be used in this project could span from basic Kalman filtering to state-of-the-art moving horizon estimation.

My Background: I am an Indian national born in Jabalpur, India. I graduated with a Bachelor in Chemical Engineering from Indian institute of Technology Bombay in 2010. I received a Master of Science in Chemical and Energy Engineering from Otto-von-Guericke University, Magdeburg, Germany in 2015. I have one year of industrial experience working as a Graduate Engineer at ONGC Petro-additions Limited, Bharuch, India and further 7 months of industrial experience working on my Master Thesis at BASF, Ludwigshafen, Germany.

My research interests include: modeling of separation processes, modeling of multiphase flows and multiphase separation, state estimation, and dynamic optimization for optimal control.
