Dr Debashree Roy B.Sc.(Hons.), M.Sc., PhD

Research Officer

Doctoral Co-Supervisor
Riddet Institute

Dr Debashree Roy is currently a research officer with Riddet Institute and is pursuing research related to food structure, digestion, and innovation projects. Her research work is supported by Riddet Institute CoRE funding ‘Future Foods in Harmony with Nature’.

Debashree completed her PhD in Food Technology in 2021 at 羞羞视频, Palmerston North, New Zealand. Her PhD research was focused on understanding the structural changes in milk of different species during digestion. During PhD, Debashree developed a keen interest in understanding how different food structures/matrices affect the delivery of nutrients during digestion and impact human health. For the first time, Debashree investigated the digestive dynamics of non-cow milks, mainly focusing on their dynamic coagulation behaviour in the stomach. Her study has potential implications for designing bio-inspired food structures for optimal delivery of nutrients. Her research work was supported by Riddet Institute CoRE funding (Future Foods Inspired by Nature).

Before joining for her PhD, Debashree worked for industrial research and development in Middle East for about 3 years (2013-2016). She completed her Master of Science in Food Technology in 2013 from Central Food Technological Research Institute (CFTRI, India). She graduated with a Bachelor of Science in Agriculture (Honours) from Bidhan Chandra Krishi Vishwavidyalaya (BCKV, India) in 2011.

Debashree joined the Riddet Institute as a Postdoctoral Fellow in 2021. Debashree has been one of the recipients of the International Dairy Federation (IDF) Pavel Jelen Early Career Scientist Award (2022) and the International Pieter Walstra Science Award (2022) for her research projects. In 2023, she won the Falling Walls Lab Aotearoa New Zealand competition with her pitch on breakthrough technology for developing plant-based cheeses.

She is also a Co-Founder and the Agricultural Material Specialist for start-up company ANDFOODS, a spin-off company dedicated to pioneering new sustainable, plant-based foods using breakthrough technology from the Riddet Institute to make a significant contribution to the food system.
