Biography

Christopher Groppi is an experimental astrophysicist interested in the process of star and planet formation and the evolution and structure of the interstellar medium. His current research focuses on the design and construction of state of the art terahertz receiver systems optimized to detect the light emitted by molecules and atoms in molecular clouds, the birthplace of stars. Development of multi-pixel imaging arrays of terahertz spectrometers is a key technology for the advancement of astrophysics in this wavelength regime. Professor Groppi is participating in several research efforts to develop advanced terahertz imaging arrays for ground based and suborbital telescopes. He also applies terahertz technology developed for astrophysics to a wide range of other applications including Earth and planetary science remote sensing, hazardous materials detection and applied physics.
