Biography

Marta Saccher was born in Trieste, Italy in 1995. She received her BSc degree in Biomedical Engineering, in 2017, from Polytechnic University of Milan. She then moved to Delft to pursue her MSc studies in Biomedical Engineering at the Faculty of Mechanical, Maritime and Materials Engineering. She joined the ECTM group of TU Delft in 2018 and moved to Eindhoven to work on her thesis on MEMS ultrasound for implantable medical devices at Philips Research. In 2019, she obtained her MSc degree cum laude and later joined the department of Biomedical Instrumentation and Signal Processing at Aarhus University as a postgraduate student.

She is currently working to pursue a PhD degree at the ECTM group of TU Delft in the framework of the European project Moore4Medical, which aims to create open technology platforms for medical devices. She is currently based at Philips Research in Eindhoven, where she is investigating the use of capacitive micromachined ultrasonic transducers (CMUTs) for implantable medical devices, to be used as means for both power transfer and ultrasound modulation of the nervous system.
