Main Interests

As an engineer I develop technical solutions and design experiments for measuring snow and ice. I am the head of the SLF cold laboratories where I develop instruments (e.g. SnowMicroPen), maintain control systems (LabVIEW) or support experiments. And supported by my long experience in harsh mountainous terrain, I regularly plan, consult and conduct snow physics field campaigns in polar regions.

Developed and Maintained Instruments

  • SnowMicroPen
  • X-ray tomography scanners
  • Instrumented X-ray sample holders (micro-compression stage, snow metamorphism stage)
  • Snow maker
  • Friction tester
  • Polarized light microscopy stage
  • Microscopes
  • Wind tunnel
