Yesterday we watched the closing ceremony for the Relativistic Heavy Ion Collider (RHIC) @brookhavenlab. For somebody like me, who started my Ph.D. in heavy ion physics in 2000, the year when RHIC started its operations, it was an emotional moment.

What a day! I started with an online talk at my former Ph.D. advisor's retirement workshop, and a few hours later I celebrated the successful Ph.D. defense of my student 🤩 I am reflecting on the impact that my advisor had on my life, and trying to propagate it forward to my own students.

It was my great pleasure to work with @fannyetienne.bsky.social, Johannes Jahan and everyone else on the #pint25 team! Already looking forward to a great #pint26! Please get in touch if you want to help organize the event in your town!

For the second time, I had the amazing opportunity to co-direct Pint of Science in the US with @claudiaratti.bsky.social and Johannes Jahan. I couldn't be prouder of all the volunteers who made this possible and grateful for our sponsors to trust us. I can't wait for the #pint26 edition🤩

#pint25 is over, and it was a big success! We sold out all evenings in Houston and in many other cities. Lots of fun discussions and interest from the audience! Many thanks to all city teams for making it possible. Mark your calendars for #pint26: May 18, 19, 20. See you next year!

New paper day! We calculate the D-measure in a hadronic vs quark-gluon plasma scenarios and compare to LHC data, finding moderate evidence for fluctuations freezing out in the quark phase. arxiv.org/abs/2504.02085

Evidence for freeze-out of charge fluctuations in the quark-gluon plasma at the LHC

The D-measure of event-by-event net-charge fluctuations was introduced over 20 years ago as a potential signal of quark-gluon plasma (QGP) in heavy-ion collisions, where it is expected to be suppresse...

New paper day! 4D equation of state for strongly interacting matter with extended coverage from first principles! www.arxiv.org/abs/2504.01881

A new 4D lattice QCD equation of state: extended density coverage from a generalized $T^\prime$-expansion

We present a new equation of state for QCD in which the temperature $T$ and the three chemical potentials for baryon number $μ_B$, electric charge $μ_Q$ and strangeness $μ_S$ can be varied independent...
