Clinical validation lead

Starting as PhD student within the project, Martine Breteler obtained her PhD entitled ‘A safer care pathway from ICU to home with wearable & wireless monitoring’ in 2021 at the University Medical Center Utrecht. 

During her PhD, she performed several clinical validation studies to verify whether current wireless sensors are accurate to measure vital signs in high-risk patients and whether such sensors could serve as a safety net in day-to-day care both on a hospital ward and at home in the early days after discharge. She combined her PhD with working for FocusCura and later on Luscii, a health IT company that develops home monitoring services for patients and healthcare professionals.  

Martine is now working as a technical physician and postdoc at UMC Utrecht where she continued to further develop, implement and study remote monitoring projects both within hospital and at home.
