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
