My research sits at the intersection of computer science, acoustics, engineering and psychology. My activities are primarily focused on modelling and simulations of sonic interactions in complex systems of virtual/augmented reality. My academic career is conceptually framed in three-levels:

1.    Immersive audio concerns the computational aspects of the acoustical-space properties of technologies. I have a strong background in computer science and engineering, having earned a MSc and a PhD in ICT Engineering at the University of Padova (2009,2014) with my theses on digital signal processing. My research gave a substantial contribution to the modelling of user acoustics, as well as to the personalization of immersive audio technologies with computationally efficient filter design and selection methods. After finalising my PhD, I contributed to the international standardization project “SOFA–Spatially Oriented Format for Acoustics” by characterizing headphones, and to “The Princeton Headphone Open Archive (PHOnA)” supported by Sony Corporation of America and Princeton University.

2.    Sonic interactions refer to human-computer interplay through auditory feedback in 3D environments; in 2016, I moved to the Department of Neurosciences - University of Verona, where I studied movement analysis and applied neurophysiological signal processing in the action-(auditory) perception loop with Prof. Paola Cesari. Cochlear R&D (U.K.), a world leader in cochlear implants, funded my work.

3.    The integration of spatial audio in multimodal VR/AR systems impacts on different application domains; in 2017 Aalborg University awarded me an international research fellowship to undertake research in Denmark with the project “Acoustically-trained 3D audio models for virtual reality applications”. I developed and tested my approaches to user acoustic personalization in several multimodal VR scenarios such as education, rehabilitation, assistive technologies and storytelling.

In 2019, I was elevated to Senior Member by the Institute of Electrical and Electronic Engineers (IEEE) as a result of my significant contributions to the profession. In 2020, I received the Scientific Accreditation at Associate Professor level in the field of computer science. My influence on the research community is evidenced by my increasing number of citations, invitations to conferences and guest lectures. In the past year at Imperial College London, I started a network of excellence granted under the EU’s Horizon 2020 project "SONICOM - Transforming auditory-based social interaction and communication in AR/VR" (gant number: 101017743, RIA action,5.5M €) by collaborating with internationally established research groups at the Sorbonne University (France), the University of Glasgow (U.K.), and the Austrian Academy of Sciences.

I was recently appointed to the post of Assistant Professor with a tenure track at the University of Udine. Starting from April 2021, I am Visiting Researcher at the Dyson School of Design Engineering, Imperial College London (UK).
The focus of my current research actions is progressively moving towards ethical and social aspects of the digital transformation, with particular attention to audio technologies in VR/AR environments integrating algorithms of artificial intelligence.
