Introduction

I am currently pursuing a PhD student In Photonics Laboratory in the Computer, Electrical and Mathematical Sciences & Engineering (CEMSE) Division at King Abdullah University of Science & Technology (KAUST).

I joined KAUST in February 2014 as an MS-to-PhD student in Photonics Laboratory and I received my MSc degree in August 2015 with a thesis based on the recombination mechanism of CH3NH3PbBr3 perovskite. I obtained my bachelor of science in Material Science Engineering from University of Padua, Italy in 2013.

My research topic focuses on enhancing the optical power of AlGaN-based nanowires light emitters. It involves the device structure design optimization and the usage of highly conductive thin metal substrates.

I am a member of OSA and SPIE and I served as a reviewer for the Journal of Nanophotonics and the Journal of Photonics for Energy.
