Dr. Kathleen Marsaglia



Kathie Marsaglia joined the Department of Geological Sciences in 2000. She is a sedimentologist with expertise in sandstone petrology, sedimentation and tectonics, and marine geology. Between graduate degrees and before coming to CSUN, she worked at various levels in the petroleum industry including several summer internships and full-time positions, the latter first as an exploration geologist and later as a senior reservoir geologist. Over her career she has spent over two years at sea on scientific cruises collecting, describing, and interpreting marine sediments and sedimentary rocks. She is a Fellow of the Geological Society of America, was an AAPG distinguished lecturer, and received both the Outstanding Faculty and Exceptional Service to Students Awards at CSUN. In 2019 she was honored by AAPG with a Grover E. Murray Distinguished Educator Award and joined the U.S. Advisory Committee (USAC) for the International Ocean Discovery Program (IODP). In 2021 she resigned from USAC to become co-chair of the IODP Science Evaluation Panel in 2022.
