Dr Mariello (Gallipoli, Italy – 1994) holds a BSc in Industrial Engineering (2015), a MSc (2017) and a PhD (2021) in Material Engineering and Nanotechnology at the University of Salento and the Center for Biomolecular Nanotechnologies of the Italian Institute of Technology (Italy). He worked on flexible microfabricated transducers and nanogenerators based on piezoelectric and triboelectric materials for energy harvesting and biosensing. He fabricated hybrid nanogenerators with record energy generation from water-based sources (e.g. waves, raindrops impacts), as well as soft biosensors for gait walking monitoring or sensing human gestures.

He was a Postdoctoral Scientist at the École Polytéchnique Fédérale de Lausanne (EPFL) since February 2021 where he worked on implantable bioelectronics and thin-film encapsulations for electrical/optical recording/stimulation. He specialized in the fields of bioelectronic implants, in vitro/in vivo deployment, photolithography-based microfabrication, biodegradable sensors, materials characterization. He patented a universal, ultra-sensitive method for quantifying accurately water permeability through thin-film encapsulations for flexible bioelectronics.

He moved to the University of Oxford (Institute of Biomedical Engineering) in 2023 as senior postdoctoral research associate for investigating laser-micromachined advanced bioelectronics and electronically-controlled drug-delivery technologies for treating neurological disorders.

So far, he is author and co-author of 18 pear-reviewed articles (13 first-author) and 3 book chapters. For a detailed CV and list of publications, please refer to his Linkedin and Researchgate profile.
