Preshanth Jagannathan

Welcome to my academic website. I am preshanth jagannathan and I work in the algorithms research and development group here at NRAO in socorro. I specialize in radio astronomy, software development, and data analysis. My current work focuses on developing and applying advanced radio interferometric data analysis techniques towards polarimetric imaging.

My active projects and recent work can be found on my GitHub.
