My research focuses on developing sustainable solutions that create value from agricultural and food processing byproducts. By combining food science, fermentation, and biotechnology, my lab transforms underutilized plant-based resources into functional food ingredients, alternative proteins, and other value-added products (smart packages and natural colors). A major goal of our research is to improve the sustainability and economics of food and bioprocessing systems through the valorization of agricultural and food side streams. We are particularly interested in developing novel fermentation media from plant protein co-products and agricultural byproducts, as well as using fermentation to enhance the functionality, nutritional quality, and flavor of plant-based ingredients. Through collaborations with industry and academic partners, we aim to translate scientific discoveries into practical solutions that support a more sustainable and resilient food system while training the next generation of food scientists and innovators.

My journey has been driven by curiosity, persistence, and a willingness to step outside my comfort zone. Growing up in Kerala, India, I developed an early interest in science and problem solving, though I never imagined becoming a professor or researcher. What motivated me was a desire to understand how things work and to apply science to real world challenges. I completed my Ph.D. in Materials Science at Trent University, Canada, where I worked on developing sustainable materials from renewable resources. During that time, I learned that research is not just about successful experiments; it is about asking meaningful questions, learning from failure, and continuously adapting. After my Ph.D., I completed postdoctoral training and spent six years in industry with companies including Louis Dreyfus Company, Noblegen, and Mane Kancor. Those experiences exposed me to alternative proteins, fermentation, microalgae biotechnology, and food ingredient development, while teaching me how to translate scientific discoveries into practical solutions. Today, as an Assistant Professor at the University of Minnesota, I focus on developing sustainable food systems through the upcycling and bioconversion of agricultural byproducts into high value ingredients and alternative proteins. Looking back, my career has been shaped not by a single defining moment, but by a series of opportunities, continuous learning, and a willingness to embrace new challenges.

Over the next decade, I see plant protein research moving beyond simply replacing animal proteins and focusing on improving nutrition, functionality, affordability, and consumer acceptance. Advances in breeding, ingredient processing, and protein characterization will continue to improve the taste, texture, digestibility, and performance of plant-based ingredients. I also believe sustainability and resource efficiency will become increasingly important. Researchers and industry will focus on maximizing the value of agricultural crops and co products, ensuring that every component contributes to the food system. As technologies for utilization and valorization continue to advance, the economics of plant proteins will become increasingly attractive. Ultimately, widespread adoption will depend not only on scientific innovation but also on consumer education and outreach. Helping consumers understand the nutritional, environmental, and economic benefits of plant proteins will be essential for building a more sustainable and resilient global food system.

My contribution is to help unlock the value of underutilized agricultural resources through upcycling and bioconversion. I believe there is tremendous potential in converting agricultural co products and food processing side streams into high value protein ingredients, fermentation media, and alternative proteins. By developing scalable and economically viable technologies, I hope to improve the sustainability, profitability, and accessibility of plant-based protein systems while reducing waste. I am particularly interested in creating pathways that connect traditional plant proteins with emerging protein production platforms, including microbial proteins produced through fermentation.

I also hope to bridge academia and industry by ensuring that research discoveries can be translated into practical solutions. Ultimately, my goal is to contribute not only new scientific knowledge, but also technologies, partnerships, and trained students that help advance a more circular and sustainable protein economy. 

Though I am excited about all the projects in my lab, I will highlight two that reflect the direction of our research. One project focuses on developing novel fermentation media from plant protein co products and agricultural byproducts. Traditional fermentation media can be expensive and often rely on refined ingredients. We are working to transform underutilized agricultural resources into nutrient rich substrates that can support the production of alternative proteins, including fungal proteins such as mycoprotein and microalgae-based proteins. The goal is to create more sustainable and economically viable protein production systems while reducing waste and increasing the value of agricultural resources. A second project focuses on using fermentation to improve the flavor and functionality of plant proteins. One of the major barriers to consumer acceptance of plant-based foods is the presence of undesirable flavors. We are investigating how microbial fermentation can reduce off flavor compounds and modify flavor precursors, resulting in ingredients with improved sensory properties and broader food applications. Together, these projects reflect our broader goal of using upcycling and bioconversion to create sustainable solutions for the future of plant based and alternative protein production.

I would probably say soybean, canola, and sunflower proteins. These crops are produced at a massive scale and generate substantial quantities of protein rich co products. While they are already widely used, I believe there is still significant untapped potential in how we utilize and add value to them. What excites me most is the opportunity to create additional value from these resources, whether as functional food ingredients or as substrates for producing alternative proteins through fermentation. Because they are already integrated into existing agricultural systems, they offer a practical and sustainable pathway for expanding protein production while making better use of the resources we already have.
