In MSAT USP Capacitance based growth modelling for cell culture. Performed fermentation experiments to generate the data. Included making experiment plan, cell thaw, forming seed train, making the media and the feed solutions. Monitoring of the experiment with daily sampling, analysis of metabolites and feeding. The experiments were run in 2L glass bioreactors, and various equipment were used during the whole process. The data generated was then analysed and optimized to create the model for cell growth.

Teva Pharmaceuticals, MSAT USP Ulm (Germany) Involved in the experimental work with the cell culture, CFD simulation and data handling. The data handling involves the pre-processing of the data and its evaluation using software like SIMCA. Literature survey for various topics and documentation was also a part of the internship.

Drying process of cohesive powders in pilot Vibrational Fluidized Bed Reactor -parameter study to evaluate the effects of mechanical vibrations of fluidized bed on the drying process -study of flow behaviour, fluidization characteristics and reactor concept -investigation of system parameters like the vibration rates, temperature and different material parameters towards the enhanced drying efficiency -periodic sampling and characterization using moisture analyser, surface morphology etc

A Project on "Numerical flow field investigation of an acoustic levitator setup in an insulating chamber" -Parameter study using Ansys Fluent to investigate the drying conditions by analysing flow field around the droplet -Investigation of the effect of gas flow during the "Single Droplet Experiment" -Simulation of the flow field inside the acoustic levitator set with the main focus around the droplet -Post-processing and evaluation of the data for the quantitative analysis

Summer research intern in the Chemical Engineering department at Calcutta University. Worked on micellar catalysis, particularly to achieve and increased solubility of organic compounds in an aqueous solution. Main reagents used for conducting the research -di-butyl phthalate which was hydrolysed in a basic solution -Cetyltrimethylammonium Bromide, a cationic surfactant

At the crude oil refinery got introduced to the downstream processing of crude oil. Learned about the working of entire plant, journey of crude oil from the initial stage as the final product of upstreaming process to the valuable final products at the end of downstream processing. Including the waste-water treatment which mainly comprised of aerobic wastewater treatment facility. Various units in downstream processing were Crude Distillation Unit, Fluid Cracking Unit, and Diesel Hydridesulphurization etc.

During the studies got introduced to a wide range of subjects like Chemical Reaction Engineering, Heat and Mass transfer, Bio-nanotechnology, Catalysis, Transport Technology, Fluid Mechanics, CFD, MATLAB, Chemistry, Mathematics etc to name a few.
