• Designed and built a service (python) for automatic modeling of the complex response of each telescope in a 63-element interferometric array directly from science data, saving $35000 USD per year in calibration observations. • Developed a parallelized service (python, dask) for imaging and localization of candidate astrophysical signals. Designed and implemented image-based reference frame corrections, reducing localization errors by a factor of 2.• Contributed to the design of the software system for real-time and autonomous analysis of a 6 TB/s data stream.• Standardized software environments across servers; designed and implemented updated policy for data storage and sharing between servers.As the Systems Scientist for the DSA-110 instrument at Owens Valley Radio Observatory:• Directed a 6-person team in commissioning hardware and software systems for a 63-radio telescope array and mobilized the effort to transition from proof-of-concept to full science capabilities.• Defined key subsystem performance metrics and coordinated the implementation of continuous monitoring of these metrics, improving detection power by more than 60%.

• Devised, implemented, and published the first algorithm for 3-dimensional imaging of small-scale Galactic structures using their effects on astrophysical signals.• Developed predictive models from intricate physical theories. Collected, analyzed, and modelled time-series radio-wave measurements from a global interferometric array of telescopes to test these theories.• Mentored undergraduate and graduate students in data analysis, inference, and scientific research.
