Sarah Dean has been teaching at 麻豆视频官网 since 2020. She joined the faculty after six years in the oil and gas industry as a production geologist and exploration geologist. She worked in the unconventional (fracking) fields in the west Texas Permian Basin, as well as deep water exploration in the Gulf of Mexico. She has experience in numerical DEM and structural restorations, as well as physical modeling.

Her courses include Planet Earth, How the Earth Works,  Intro to Environmental Science, Regional Geology, and Structural Geology. She also teaches a First Year Seminar on Science and Christianity: are they in conflict or accord with one another?

Dr. Dean got into geology due to her love of field work, then ironically spent 10+ years studying the subsurface in a lab and on a computer. At Hope, she鈥檚 enjoyed stepping back into field work: her lab students visit dunes near campus with her regularly, and her Regional Geology class does field work with her in Utah.

AREAS OF INTEREST AND EXPERTISE

Dr. Dean鈥檚 current research focus is salt and shale tectonics, focusing on the Gulf of Mexico.

Her research investigates shale tectonics of passive margins using physical models. In other words, they have fun making a mess by creating deltas out of clay to simulate real geologic processes 鈥� looking at the implications for both geologic hazards and opportunities in the Gulf of Mexico鈥檚 oil and gas province. Her student researchers make clay slurries, help run experiments, and analyze the results through section analysis and video analysis using MATLAB and PIV.

Previous Research Projects

• Created computer models to study the formation of structures in fold and thrust belts in the Canadian Cordillera
• Created computer and physical (sand and clay) models to study the shale tectonics of the Niger Delta
• Collected and analyzed seismic data (on board the R/V Marcus G. Langseth) off the coast of Spain to study the rifting of the Atlantic margin in a sediment and magma poor location.

OUTSIDE THE COLLEGE

Dr. Dean enjoys reading, crafts and hiking (does this count as geology when you do it to look at rocks?). Her vacations are usually devoted to chasing her niece and nephews around and trying to tempt them into science experiments. Every fall she can be found hunched over her sewing machine with a hot glue gun in one hand and a crochet needle in the other, making them Halloween costumes. Some projects are more successful than others!
