Summary
🤩
Rockstar🎓
Top SchoolMatteo Bachetti is a staff scientist at INAF with 11 years of experience as an astrophysics researcher specializing in accretion onto compact objects and multiwavelength observational analysis. He combines deep expertise in X-ray satellite data (NuSTAR, XMM, RXTE, Chandra) with radio instrumentation work and theoretical modeling, and spent a year as a Fulbright visiting scholar at Caltech working on NuSTAR timing and mission planning. Matteo is an active open-source contributor—having improved astropy’s modeling and HDF5 metadata handling and extended the PRESTO pulsar toolkit for the Sardinia Radio Telescope—bringing research-grade software engineering to astronomy projects. Trained with a PhD in Physics from Università degli Studi di Cagliari, he is known for bridging rigorous data analysis, instrumentation support, and reproducible code in observational astrophysics.

Back-end Developer
Back-end DeveloperContributions:35 commits, 3 PRs, 24 comments in 6 years 2 months
Contributions summary:Matteo primarily contributed to the `presto` toolkit by adding support for the Sardinia Radio Telescope (SRT). Their work involved modifying several core files, including `misc_utils.c`, `polycos.c`, and `sigproc_fb.c`, to incorporate SRT into observatory lists and configurations. Further contributions include fixing string issues and addressing code style issues.

Role in this project:Back-end Developer
Back-end DeveloperContributions:55 reviews, 68 commits, 16 PRs in 7 years 4 months
Contributions summary:Matteo primarily contributed to the `astropy/astropy` repository by modifying and enhancing the `astropy.modeling.optimizers` and `astropy.io.misc.hdf5` modules. They fixed a bug in the Simplex optimization method by correctly passing keyword arguments and handling accuracy-related parameters. Furthermore, the user implemented and tested features for saving metadata, including column units and dictionaries, within HDF5 files and added tests to ensure preservation of the new features.
