Summary
👤
Senior🎓
Top SchoolJosh Borrow is a Systems Architect with 11 years of experience building data management and visualization infrastructure for large-scale astrophysics projects, currently leading Data Delivery for the Simons Observatory at the University of Pennsylvania. He combines hands-on HPC and parallel I/O expertise—developed during his postdoc at MIT where he built multi-TB HDF5 visualization pipelines and integrated a novel galaxy-formation model into the Arepo code—with production-facing system design for public data access (PI of the NSF "socket" project). An active open-source contributor and editor for the Journal of Open Source Software, he has made targeted improvements to the widely used yt project to better handle cosmological datasets. Trained as a computational astrophysicist with a PhD from Durham, he brings a rare mix of scientific modeling, scalable engineering, and data-delivery pragmatism to observational and simulation workflows.

Contributions summary:Josh primarily contributed to the scientific computing project by improving the handling of cosmological data within the Gadget frontend. They addressed issues with missing redshift information, implemented a fallback mechanism, and added corresponding tests. Furthermore, the user fixed an indexing issue related to NumPy and made code style adjustments by refactoring function names and improving the handling of comments in Enzo data structures. This included a change to search for '=' signs to account for valid comments.
