Summary
👤
Senior🎓
Top SchoolParker Fagrelius is an instrumentation scientist and observatory leader with 11 years of experience delivering complex optical and spaceflight systems, currently serving as Mayall Telescope Site Director and Associate Scientist at Rubin Observatory. He holds a PhD in Physics from UC Berkeley for work on DESI and continues hands-on integration, testing, and on-telescope commissioning of DESI focal-plane hardware. Prior to graduate school he led a >20-person team at JPL as Project Manager for the OPALS lasercomm payload on the ISS, blending systems engineering, program management, and cross-organizational stakeholder coordination. Parker is fluent in Python-based data analysis and highly multiplexed fiber spectrograph instrumentation, and he pairs that technical depth with practical operational experience running major ground-based facilities. An uncommon mix of spaceflight project delivery and ground observatory commissioning gives him a rare end-to-end perspective on turning precision instruments into science-ready observatories.
