Dr. Alessandro Fasano is an instrumental astrophysicist specializing in the design, modeling, and deployment of millimeter- and submillimeter-wave instruments for cosmology. His work bridges engineering innovation and cosmological observation, advancing detector technology to enable precision measurements of the early Universe.

He earned his PhD (2017–2020) jointly at Institut Néel and LPSC–CNRS Grenoble, where he developed simulation frameworks and KID-based spectrometers for cosmology. He was a main contributor to the commissioning and characterization of the KISS experiment, gaining extensive experience in instrument deployment, calibration, and on-sky performance validation.

From 2020 to 2023, as a postdoctoral researcher at the Laboratoire d’Astrophysique de Marseille (LAM), he served as the modeling and hardware specialist for the ERC-funded CONCERTO spectrometer at APEX (Chile), leading system modeling, calibration design, and stability control during high-altitude field campaigns.

Since 2023, at the Instituto de Astrofísica de Canarias (IAC), he is the contact person and a major contributor for the GroundBIRD experiment, responsible for maintenance, observation coordination, and systematic mitigation. He also leads calibration activities for QUIJOTE, combining laboratory modeling with operational expertise to deliver high-precision cosmological data from the Northern Hemisphere.
