Summary
👤
Senior🎓
Top SchoolEric Neilsen is a computational physics developer with 11+ years of experience applying astronomy and software engineering to large-scale sky surveys, observing operations, and astronomical data processing. Based at Fermilab, he builds and maintains software for survey scheduling, observing efficiency, and distribution of processed data, drawing on a PhD in astrophysics and hands-on observatory experience from his time at Johns Hopkins and the Sloan Digital Sky Survey. He combines scientific rigor in image analysis and photometric calibration with practical systems thinking, automating observing workflows and operational tools that improve nightly photometric solutions. His background blends research-quality data analysis (including HST image work on galaxy clusters) with IT and management training, enabling him to bridge research teams and production computing. Notably, his career reflects a long arc from developing custom image-analysis pipelines to architecting survey-scale software at a national laboratory, emphasizing reproducible, open-science practices.
