Shreyasi Chattopadhyay

Postdoctoral Researcher, 2018 – Present
Shreyasi joined JTSI group as postdoctoral researcher in November, 2018. She completed her B.Sc. and M.Sc. in Chemistry from Jadavpur University, India. Shreyasi pursued her PhD research in CSIR-Central Glass and Ceramic Research Institute and received her doctorate degree in May 2018 from Jadavpur University, and then moved to St Andrews. The objective of her PhD research was to develop new hierarchical nanostructured TiO2 materials and to study their efficiency mainly in photocatalysis and DSSCs. In JTSI group Shreyasi is working in the project entitled ‘Emergent Nanomaterials’. Aim of her research work here is to explore exsolution chemistry towards growth of emergent nanoparticles in titanate-based perovskite oxides.
