I am an Associate Professor in the School of Sustainable Energy Engineering (SEE), Simon Fraser University, Canada. Concurrently, I am the Head of the “Pecunia Research Group – Sustainable Optoelectronics”, which I founded in 2016. My group’s multidisciplinary research is at the intersection of materials science, physics, and electronics engineering. Specifically, I investigate emerging, environmentally friendly, printable semiconductors, such as organic semiconductors, lead-free perovskite-inspired materials, amorphous metal-oxide semiconductors, and carbon nanotubes. My interest in these semiconductors is motivated by their considerable potential for easy-to-make and environmentally friendly (opto-)electronics and photovoltaics, which could be deployed ubiquitously to enhance the sustainability of our daily lives. 

My research focuses on the experimental characterization and conditioning of the optoelectronic properties of these materials, as well as their device applications in solar cells, thin-film transistors, and photodetectors. By gaining a detailed understanding of their optoelectronic and device properties, I seek to rationally realize the full potential of these semiconductors for optoelectronic and photovoltaic applications. My ultimate goal is to develop semiconductor technologies that can contribute to the reduction of electronic waste, provide low-cost green energy, and enable the sensorization of our homes and cities for more sustainable living.

Prior to establishing the Pecunia Research Group, I worked full-time for over six years at the Optoelectronics Group of the Cavendish Laboratory, University of Cambridge. Whilst there I earned my PhD in Experimental Physics and worked as a Postdoctoral Research Associate under the supervision of Professor Henning Sirringhaus. Before that, I completed my BSc and MSc in Electronics Engineering at Politecnico di Milano, Italy, where the MSc also included a joint program with the University of Texas at Austin, USA.

I have published numerous research articles in highly reputable peer-reviewed journals such as Nature, Advanced Materials, Advanced Energy Materials, Nano Energy, Advanced Functional Materials, Advanced Optical Materials, and Nano-Micro Letters. Moreover, drawing from my research experience, I have also authored the books Organic Narrowband Photodetectors (Institute of Physics Publishing) and Organic and Amorphous-Metal-Oxide Flexible Analogue Electronics (Cambridge University Press).

I serve on the Editorial Boards of the journals Nanotechnology, Journal of Physics: Materials, Springer Nature Applied Sciences, and Frontiers in Electronics. I am Co-Editor of the Research Topic entitled “Next-Generation Optoelectronics with Emerging Hybrid Materials” for Frontiers in Electronics, as well as the Research Topic entitled “Current & Emerging Trends in Renewable Energy Harvesting Technologies” for Frontiers in Sustainability. Additionally, I am the Lead Guest Editor of the Focus Issue entitled “Grand Challenges in Halide Perovskites: Next Generation Photodetectors” for Journal of Physics: Materials, and Lead Guest Editor of the Focus Issue entitled “Green Nanomaterials for a Sustainable Internet of Things” for Nanotechnology.

I am a Fellow of the Institute of Materials, Minerals and Mining (FIMMM), a Senior Member of the Institute of Electrical and Electronics Engineers (SMIEEE), and a member of the Institute of Physics (IOP) and the Materials Research Society (MRS).
