Dr. Stephen Schellenberg, Ph.D.

Associate Dean, Division of Undergraduate Studies 


Dr. Stephen Schellenberg

Dr. Stephen Schellenberg, the Associate Dean of Undergraduate Studies, earned his BA and MS at the University of South Florida and his PhD at the University of Southern California, with an extended pre-doctoral residence at the Smithsonian National Museum of Natural History. After a National Science Foundation Post-Doctoral Fellowship at the University of California, Santa Cruz, Stephen joined the SDSU Department of Geological Sciences in 2002 and was promoted to Full Professor in 2013.


Dr. Schellenberg’s disciplinary interests include paleobiology, paleoecology, paleoclimate, geochemistry, and biomineralization. Specifically, he explores how the chemistry of animal skeletons, mainly mollusc shells, can inform our understanding of ancient biology, ecology, and climate. He also explores what the fossil record of ostracodes, small arthropods that produce the only numerically-significant multicellular fossils in the deep-ocean, can reveal about the history and dynamics of this vast ecosystem with respect to the ocean-atmosphere circulation and global biogeochemical cycles.


In addition to these disciplinary endeavors, Dr. Schellenberg is committed to effective student-centered learning through face-to-face and fully-online modalities using a strategic blend of assessment, technology, and high-impact practices. As a faculty member, he has developed and implemented core major courses, General Education Foundation and Exploration courses, advanced graduate seminars, and an honors seminar. As Associate Dean, he is engaged in promoting student success across the institution through facilitating the division’s myriad programs, implementing the SDSU Strategic Plan, and preparing for the upcoming WASC re-accreditation process.


A firm believer in both shared governance and academic duty, Dr. Schellenberg has a strong commitment to service on local to global scales. Within SDSU, he serves as a university senator, chair of the senate Academic Policy and Planning committee, and chair of the senate-appointed Student Learning Outcomes committee. Regionally, he collaborates with the National Park Service at Cabrillo National Monument in disciplinary research and docent training and serves annually as a judge at the Greater San Diego Science and Engineering Fair. Internationally, he serves as co-director and instructor for the Urbino Summer School in Paleoclimatology, which provides seventy-five graduate students from around the world with an intensive three-week immersive experience each summer in the methods, data, and models used to reconstruct the history and dynamics of the global climate system.
