Dr Ronak Janani BEng, PhD

Research Fellow


I completed my PhD focused on sol-gel chemistry and energy storage in 2019 at Sheffield Hallam University. With the use of my background in sol-gel chemistry, I entered the field of biomaterials with a focus on bioactive glass ceramics for healthcare applications. I later joined the iPSpine consortium to contribute to the development of smart biomaterials as part of a non-invasive therapy for disc degeneration.

Over the years, I also took part in several Innovate UK and UKRI projects (such as EnviroAsh, Enviroglass 2 and GRIFFIN) helping to address some of the challenges faced by UK’s Foundation Industries. In 2022, I became PI for the HiT OFCs project which aimed to advance the TRL of a developing gas-Raman instrument designed for emission monitoring in several UK Foundation Industries.
