About netjiro

bbq, chat, sail, surf, swim, dive, bike, run, climb, kayak, think, discuss, code, write, play.

I run tricky R&D projects. From inception to product and spinoffs.

Collaborative efforts spanning multiple disciplines, countries and cultures. Usually around 15-30ppl, 2-5y, 5-10 organisations. Mainly in medtech / biotech, fintech, computational modelling. Too curious to focus, often stray outside my comfort zone.

Work globally. Based in Liechtenstein / Zürich / München, Gothenburg / Oslo / Copenhagen. Mostly consulting, sometimes entrepreneurial, occasionally employed.

20y R&D leadership, 10y academic research. PhD on computational physics in medicine.
