Short Bio

I, Dr. Winny Routray joined as Assistant Professor in the Department of Food Process Engineering at NIT Rourkela in February 2020. I have also been working as the Associated Graduate Faculty at University of Guelph, Canada. I received my Ph.D. in Bioresource Engineering from McGill University, Canada under the supervision of Prof. Valerie Orsat, where I was a Graduate Excellence Fellow. I received 2015 Best Graduate Thesis Award for best Ph.D. thesis awarded by the Canadian Society for Bioengineering. Afterwards, I moved to Memorial University of Newfoundland for my post-doctoral work, where I carried out vibrant research activities in nutraceuticals and biofuels. I also worked as Senior Research Associate on projects focussed on bioplastic production employing leather industry and agricultural waste at CSIR-CLRI, Chennai and CSIR-IMMT, Bhubaneswar. I have also completed Post Graduate Program in Data Science from Purdue University, USA in 2020. My main research interests encompass many aspects of food and post-harvest engineering, by-product utilisation and waste valorisation through bio-processing, downstream processing and microbial applications, with the general themes of exotic frontiers of bio-engineering including, biofuels, nanocellulose, sustainable biomaterials production and value-added product development from agricultural and industrial waste and by-products. I am also working on the application of Data Science and Machine Learning in the field of food and agriculture. Apart from research activities, I have keen interest in transfer of knowledge between academia and industry, mentoring of students and fresh entrepreneurs, and outreach activities.
