Dr. Jayeeta Mitra graduated in Agricultural Engineering from Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, West Bengal. From the very beginning she was inclined towards processing and preservation of foods because very less amount of processing done in our country although it tops in production. At the same time there is huge loss of produce due to lack of proper preservation practices. Hence, she decided to continue further education in Food Process Engineering. She completed Masters in Food Process Engineering from G B Pant University of Agriculture and Technology, Pantnagar in 2006 and immediately joined as research scholar in Agricultural and Food Engineering Department of IIT Kharagpur. She earned her Ph.D in 2010.

She started her career as Assistant Professor in Centre of Food Science and Technology, Institute of Agricultural Sciences at Banaras Hindu University, Varanasi. In 2012 she joined as Research Engineer in an ICAR-ICMR funded project and continued for some time. However she had a keen interest to pursue academic career. In 2014 Feb, she started working as Assistant Professor in Food Process Engineering Department at NIT Rourkela. She joined IIT Kharagpur as Assistant Professor in Agricultural and Food Engineering in November 2014.

She has guided 6 M.Tech (Food Process Engineering), 1 M.Sc (Food Science and Technology) students and currently supervising 2 Research scholars. Her research group is working on  developing feasible solution for food packaging and preservation or storage using macromolecules. The two applications have been tried so far are bionano coating of macromolecules to extend shelf life of fruits and enhancement of mechanical and barrier properties of biofilm.

She works in RuTag, which is a socially challenging project aimed to empower the rural or marginal farmers by providing them low cost mechanised solution for farming and post-harvest processing. She contributed in design and development of Motorised Dhenki and doormat making machine; small scale paddle cum motor operated rice flaking machine.
