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

Postdoctoral Fellow

Doctoral Co-Supervisor
Riddet Institute

Debashree completed her PhD in Food Technology in 2021 at Massey University, 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 is currently pursuing fundamental and applied research for the development of novel technologies to design structurally and nutritionally superior future foods. Her research work is supported by Riddet Institute CoRE funding ‘Future Foods in Harmony with Nature’.
