Rylie Green
Lead Researcher
Dr Rylie Green joined the Bioengineering department at Imperial College London in 2016. She received her PhD (Biomedical Engineering) from the University of New South Wales, Australia in 2008. Dr Green’s research has been focused on developing bioactive conducting polymers for application to medical electrodes, with a specific focus on vision prostheses and cochlear implants. Specifically, she has been investigating the application of bioactive electrode coating technologies to a developmental bionic eye device (with Bionic Vision Australia), and commercial cochlear implants (with Cochlear Ltd). More recently Dr Green has developed hybrids of conducting polymers and hydrogels to reduce strain mismatch with neural tissue and improve long-term cell interactions at the neural interface. This has led to her development of tissue engineered “living electrodes”, a new concept funded by an ERC Consolidator grant, which will allow neural cells to synaptically interface with bionic devices. Dr Green has ongoing collaborations with a range on industry partners including Galvani Bioelectronics, Boston Scientific and OxSyBio.

Sofia Peressotti
PhD Student

I am a Bioengineering PhD student. My interests include the development of interventional approaches for clinically viable brain regeneration platforms. I investigate the effect of electrical stimulation on neural stem cells encapsulated in a bioactive self-assembling peptide, towards a combinatorial treatment for Alzheimer’s Disease. The stimulation technique exploits temporally interfering fields (TI), an expertise developed in collaboration with the Interventional Systems Neuroscience Lab (Dr Nir Grossman, Division of Brain Sciences, Imperial College London). I previously completed a MSc in Bioengineering at Imperial College London with a focus on Biomaterials and Tissue Engineering, and a BSc in Biomedical Engineering at Politecnico di Torino, Italy.
