Research interests

I am an experimentalist with a broad range of research interests. My interests extend from novel quantum technologies and quantum nano-electronics to nano-photonics, plasmonics and THz opto-electronics. My research direction at the UoG is on Ultrafast Quantum nanoElectronics. 

My research interests extend over a broad range. I studied for my MSc and PhD in the fields of ultrafast optics, nano-photonics and plasmonics and focussed on THz plasmonics and metamaterial devices. 

After finishing my PhD, I was very interested on novel quantum technologies and I radically changed my research field to Quantum nano-Electronics. I did research on innovative single electron sources, that can produce single electron wave-packets that are well-defined in the time domain. These wave-packets can be used to access in real-time ultrafast quantum mechanics, and observe timelapses of how electrons interact with their environment. 

My research direction at the UoG will be towards creating Ultrafast electron wave-packets with 1 ps time duration (or THz bandwidth), by combining: quantum nano-electronics, nano-photonics, plasmonics and THz opto-electronics.

My long term vision is to create the first THz qubits that can be used in future quantum technologies.
