David Maria Tobaldi obtained his MSc in Geology and PhD in Materials Science both from the University of Bologna, Italy. He was visiting scholar at the Department of Chemical Engineering, University of Patras, Greece (2007), Slovenian National Building and Civil Engineering Institute, Ljubljana, Slovenia (2008), Shanghai Institute of Ceramics, China (2009). From 2011 to 2020 he served as PDRA at the Department of Materials and Ceramic Engineering/CICECO—Aveiro Institute of Materials, University of Aveiro, Portugal. He currently is a research associate at the CNR-Nanotec, Nanotechnology Institute, Lecce, Italy. He has published >100 papers, having an h-index of 32, >2500 total citations (Scopus). His research interests cover structural and microstructural analyses via advanced X-ray methods; (multi)functional application of titania-based nanomaterials – for photochromic, photocatalytic, antibacterial and light-to-energy functionalisations. He is expert in photocatalysis and pioneer in hybrid inorganic photochromic multifunctional materials. His current research interests are: - light to matter interaction at the nanoscale; - photocatalysis for antipollution, self-cleaning and antibacterial self-sterilising materials; - multifunctional TiO2-based photocatalysts -- havingtuneable/coupled optical-magnetic-electrical-sensing properties; - inorganic visible-light photochromic nanomaterials; - energy materials and sustainable hydrogen generation. * He is Topic Editor for the journal Nanomaterials * He was an Editorial Board Member of Nanoscience & Nanotechnology-Asia. * He is in the scientific program committee of the ICAFMC2018, to be held in Barcelona, Spain, September 5-7 2018. * He is in the scientific program committee of the IWMSE2018, to be held in Xi'an, PRC, May 18-20 2018. * He was in the scientific program committee of Nano-Micro Conference 2017, sponsored by the Nature Research Society, and held at the Jiao Tong University, Shanghai, PRC, June 19-23 2017.
