Dr. Elena Sacchi

Since January 2024 I am part of the Supercomputing and E-Science group, working on PUNCH4NFDI software and data infrastructure, digital research products, and workflow engines such as REANA.

I joined the AIP in November 2020 in the Milky Way and Local Volume group, to work on the formation and evolution of galaxies in the nearby Universe through the analysis of their resolved stellar populations.
