Sergio Sanabria, Ph.D.

Scientific Research Staff

Sergio J Sanabria was born in Vitoria, Spain, in 1984. He received a M.Sc. degree in Telecommunications Engineering from the University of the Basque Country, Bilbao, Spain, in 2007, a Ph.D. degree from ETH Zurich, Switzerland, in 2012 (non-destructive testing of timber materials with air-coupled ultrasound), and a habilitation as Instructor from University of Zurich, in 2020 (ultrasound physics and image processing). From 2012 to 2014, he was a postdoc at the Institute for Building Materials of ETH (multi-scale bio-composite imaging based on neutron and synchrotron tomography), from 2014 to 2017 he was Senior Assistant at the Computer Vision Laboratory of ETH (co-lead of ultrasound elastography research), and from 2017 to 2018 a Pioneer Fellow/founder at the Innovation and Entrepreneurship Laboratory of ETH (translation of breast cancer diagnosis technology based on pulse-echo ultrasound tomography), from 2018 to 2020 a Medical Physicist at University Hospital of Zurich (clinical validation of sarcopenia quantification based on speed-of-sound) and from 2021 a tenure-track Ikerbasque fellow at the University of Bilbao (artificial intelligence for biomarker discovery based on combinations of ultrasound raw data and  blood-based essays). In 2022 he joined the Dahl Lab as a Research Scientist/Engineer. His current-research interest is in prospecting tissue composition with multimodal ultrasound imaging by reconstructing acoustic properties and tissue angiogenesis. He works in close collaboration with ultrasound manufacturers and clinical partners to develop and translate new ultrasound sequences into medical products. Current clinical applications are staging of non-alcoholic fatty liver disease (NAFLD) and providing early stage indications of immunotherapy response in metastatic renal carcinoma (mRCC).
