WELCOME! to the web site of Seth Redfield at Wesleyan University in Middletown CT, where I am an Assistant Professor
in the Astronomy Department.
These pages outline my research interests, which focus on the
three-dimensional structure of the Local Interstellar Medium (LISM) and its influence on the heliosphere and astrospheres, circumstellar and planetary systems around nearby stars,
stellar and exoplanetary atmospheres, and high-resolution spectroscopy.
