Summary
👤
Senior🎓
Top SchoolTyler Desjardins is a Principal Staff Scientist and Deputy Branch Manager at the Space Telescope Science Institute with nearly two decades of experience bridging astrophysics, observatory operations, and data-driven software workflows. He leads a ~20-person Roman Telescope Branch, coordinating science feedback, data processing, archiving, and mission operations across multiple ground-system elements while working closely with engineers under both agile and long-term project planning. Previously he supported Hubble’s Advanced Camera for Surveys—running calibration programs and serving as the polarimetry expert and HST help desk lead—bringing hands-on instrument and user-support experience to mission-scale operations. His research blends multiwavelength studies of galaxy evolution, compact objects, and AGN with practical data-analysis tooling; he contributes Jupyter-based notebooks and FITS-processing pipelines for the community. Based in Baltimore, he combines science leadership with day-to-day data-science craftsmanship, including image combination, alignment, and satellite-trail mitigation techniques that improve archival science return.
