James M. Cordes holds the George Feldstein Professorship in Astronomy at Cornell University, affiliated with the Department of Astronomy within the College of Arts and Sciences. He maintains dual associations with the Carl Sagan Institute and the Center for Radiophysics and Space Research (CCAPS), conducting observations across global facilities including Arecibo Observatory, the Very Large Array, Parkes Telescope, and space-based instruments like Hubble and Chandra.
His research centers on pulsar astronomy as a tool for fundamental physics, with expertise in radio signal processing, interstellar medium studies, and the search for extraterrestrial intelligence. Cordes pioneers statistical inference methods for gravitational wave detection and leads development of next-generation instrumentation like Arecibo's multiple-feed receiver system, while serving as a key contributor to the international Square Kilometer Array project.
Analysis of Cordes's 2008–2012 publications reveals a cohesive research program using pulsars to probe spacetime curvature near black holes, detect gravitational waves, and investigate galactic center environments. His work consistently integrates multiwavelength observations with innovative data analysis, establishing foundational methodologies for pulsar timing arrays and demonstrating how circumpulsar phenomena can reveal hidden astrophysical structures.
Cordes collaborates through the Carl Sagan Institute team and major consortia including NANOGrav. His observational campaigns coordinate radio, optical, infrared, and gamma-ray facilities worldwide—from Arecibo upgrades to Hubble Space Telescope campaigns—enabling breakthrough studies of cosmic plasma environments and gravitational phenomena, as highlighted in Cornell's coverage of the 2020 gravitational wave 'hum' detection.
