POSTDOCTORAL ASSOCIATE, Haystack Observatory-Astronomy, to play a significant role in the radio astronomy group and contribute to ultra-high-angular-resolution studies of supermassive black holes and active galactic nuclei and related software development for the Event Horizon Telescope (EHT) and other radio interferometers. Current relevant research programs include astrophysical research of Sgr A*, M87, and other active galactic nuclei conducted with EHT and other radio astronomy instruments; ground and space expansions of the current EHT array in the area of software systems, receivers, correlators, data recorders, and overall telescope and array operations; development of advanced imaging and calibration techniques for interferometer data; application of machine learning techniques to research problems in astronomy and other research fields pursued at Haystack (e.g., geodesy and ionospheric studies); and development of astronomy analysis software and pipelines in high-performance computing systems involving GPUs and/or computing clusters. PIs are committed to comprehensive mentoring following MIT’s standard for postdoctoral training and offer a high degree of autonomy within the limits set by the project funders.
