Dr. Sheehan was a CIERA Postdoc from 2019 – 2022.
Patrick Sheehan studied the structure of protostellar disks, searching the youngest known disks for signs that planet formation has begun, and measuring protostar masses in order to constrain pre-main sequence evolution. Patrick also worked on CIERA’s outreach and education activities, including coordinating CIERA’s summer research program for high school students.
