👋

My name is Jean-François "Jeff" Schaff. I go by @jfschaff on the internet.

I have built atomic clocks ⚛️⏰ and co-founded the e-health startup Postelo 👩‍⚕️.

E-Health

Postelo was a telemedicine platform focused on medical advice between healthcare professionals. It was acquired in 2023 after we had difficulties finding a sustainable model for it.

I now work in the e-health sector for the French State.

Quantum Physics

I was an experimental quantum physicist between 2008 and 2017, both in academia and in a startup.

Thoughts

I sometimes write in my blog.
