About the Speaker

 julia wellner

Dr. Julia Wellner is a marine geologist who works primarily offshore Antarctica on questions related to the sedimentary record of glacial variability, climate history, and sea-level change.  Wellner has completed over a dozen ocean-going cruises collecting geophysical data, surface samples, and drill cores, including ten seasons in Antarctica.  Most recently, she served as the Co-Chief of International Ocean Discovery Program (IODP) Expedition 379, Amundsen Sea West Antarctic Ice Sheet History.  Next season she will be back in Antarctica as part of the International Thwaites Glacier Collaboration.

She and her students also work in the Gulf of Mexico, examining details of recent stratigraphic units as analogs for petroleum reservoirs and on coastal response to sea-level rise.  They use donated data as well as collect new data in shallow water using their own boat, the R/V Mishipeshu.

Julia completed a tour as an American Association of Petroleum Geologists (AAPG) Distinguished Lecturer in 2016 and now serves on several AAPG committees.  She volunteers to lead coastal field trips for many local meetings, including the upcoming 2020 AAPG meeting.

She earned her Ph.D. in 2001 in Geology and Geophysics from Rice University, where she also completed a post-doctoral fellowship.  She has been at the University of Houston since 2006 where she teaches stratigraphy, sequence stratigraphy, marine geology, oceanography, and field courses in facies interpretation.  She received the Outstanding Faculty Award from the UH Alumni Association in 2015 and served as a UH Energy Fellow in 2016-2017.
