Starting as a graduate student studying masers in star-forming regions, I have specialized in radio interferometry, especially the technique of very long baseline interferometry (VLBI). The EHT applies VLBI to the highest frequencies used in radio astronomy in order to make the highest-resolution astronomical images taken from the ground. I work on EHT operations, including scheduling and data quality assurance, and I serve on the EHT Science Council. I also help run the Haystack Research Experiences for Undergraduates (REU) program.
The Event Horizon Telescope is obtaining images of nearby supermassive black holes with ultra-high angular resolution to see down to the scale of the event horizon.
