Summary
I am currently a UKRI Future Leaders Fellow at the Centre for Electronics Frontiers at the School of Electronics and Computer Science in the University of Southampton.
Previously I was a Research Associate in the Department of Materials, Imperial College London. I worked on an EPSRC Knowledge Transfer Secondment project, in close collaboration with PragmatIC, a UK-based SME that develops ultra low cost flexible electronics for smart packaging applications based on RFID and NFC technologies.
Prior to this position, I was a Marie Sklodowska-Curie Fellow in the Experimental Solid State Physics group (EXSS) at the Blackett Laboratory, Department of Physics, Imperial College, in the group of Professor Thomas Anthopoulos. The main focus of “A-LITHIA” project was to explore the scalability potential of a novel patterning technique, adhesion lithography (a-Lith), into large area flexible substrates. In parallel, I followed a multidisciplinary research trajectory aiming at the development of high performance co-planar nano-scale electronic devices on the a-Lith patterned substrates, the architectures and dimensions of which would be difficult or far too expensive to obtain with traditional patterning techniques (e.g. e-beam lithography).
Targeted proof-of-concept applications included:
- radio frequency rectifying Schottky diodes
- light-emitting diodes (LEDs)
- photodetectors
- resistive switching memories
- molecular nano-junctions
My broader research interests involve the following:
- photochemical tuning of emission colour of fluorescent and phosphorescent emitters for application in polymer light-emitting diodes (PLEDs)
- solution-processed organic and inorganic materials used as interfacial layers in PLEDs and organic photovoltaics (OPVs)
- synthesis of mesoporous nanocrystalline TiO2 for application in dye sensitized solar cells (DSSCs)
I am also interested in undertaking consultancy projects. Please contact me to discuss more on your queries or technical challenges.
