Portrait Helene Isler

Helene Isler
Dr. sc. ETH

Wissenschaftliche Mitarbeiterin Klinik für Neonatologie


  • MSc Physics ETHZ
  • MAS Medizinphysik ETHZ
  • PhD at BORL

Helene Isler studied Physics at ETHZ (Swiss Federal Institue of Technology in Zurich) and obtained her MSc degree in 2013. She started her PhD at the BORL group right afterwards and followed a Master of Advanced Studies in Medical Physics at ETH simultaneously. She finished her MAS degree in 2016. Her PhD is in the field of near infrared spectroscopy (NIRS) and its application in a clinical setting. She is interested in abdominal tissue oxygenation monitoring specifically as low levels can point to dangerous health conditions. Ms. Isler also works on phantoms to test NIRS devices on their function as well as to allow for calibration and verification. Silicone phantoms with long durability and stability as well as short-lived but highly human-like blood phantoms belong to her expertise.
