Our field has lost a giant. I will never forget his talk I heard as a master student in Tokyo. It was very inspiring for someone so young. However, I am not sure how much the rest of the audience benefited - the French accent was superb, too 🇫🇷 Anyway, I asked the only question 🤭

Medical data protection is important and I do understand that the German laws for doing research with them are rather strict. But why is it allowed that private health insurances insist on you signing to lift all restrictions and allow them to store everything forever?

Anna Poetsch @apoetsch.bsky.social · 01/04/2026
Yes, I am familiar with those. Really nice work. I meant rather concretely modelling in infections. To achieve something like "one flu accelerates a particular CHIP phenotype by x months/years on average". I think such rather simple conclusions are important to advertise prevention efforts.

This is really a substantial change 😯. I wonder what else one would need to properly model the relationship between infection and clonal hematopoiesis. It does not seem totally out of reach... Ill think about that 🤔 This is really interesting!

And has anyone excluded a relationship with vaccinations? I am just asking, because for people to infer a link, is of course not a big leap…

I love this initiative. I think generally it would be great to have a grant system for providing basic income, if private citizens propose something that enriches society. This could be art, literature, building up something. It may even make sense for doing science or humanities.

My comment was specifically about MSCA, where I was (as a reviewer) shocked about the review process. For ERCs it is a completely different evaluation system.

Anna Poetsch @apoetsch.bsky.social · 09/02/2026
Yes, indeed. At the same time I have always been wondering whether it is a good idea to focus so much on PhD students with project funding. It might be worth shifting it a bit to postdocs to accommodate this bottleneck and at the same time the numbers in the system would go down.
110
Anna Poetsch @apoetsch.bsky.social · 09/02/2026
But how do you want to fix it? I understand the plan to reallocate big funds from super-PIs to the base, but ultimately - even then - money will be the limiting factor. So do you think the numbers of applicants should go down? And if yes, how would that be done?
120
Anna Poetsch @apoetsch.bsky.social · 09/02/2026
Well, for MSCA the review process is broken. It is mostly all about whether it is written the right way, much less about the content. What brings it over the threshold, is whether the candidates were advised properly on how to write it.
