The College of Earth, Ocean, and Atmospheric Sciences (CEOAS) at Oregon State University is pleased to re-open the search for four (4) research-focused, tenure-track, open rank professor positions, who maintain or have the potential to maintain sea-going research programs. This is a cluster hire that promotes interdisciplinary research across four focus areas: Biological Oceanography, Chemical Oceanography, Physical Oceanography, and Marine Geology and Geophysics. Applications to more than one position is suggested for candidates with interdisciplinary focus. Given the extensive delay in this hiring action we are inviting new applicants as well as encouraging previous applicants to update their application materials. We seek faculty members who will develop and maintain vigorous, externally funded, sea-going research programs. We particularly welcome applications from individuals with interests that complement or strengthen existing CEOAS research areas, and will instigate new and innovative college- and university-wide, national and international oceanographic research programs. Review of applications will begin on April 16, 2021 and continue until April 30, 2021.
