Dr. Jillian Maloney joined the SDSU faculty in 2015 as an Assistant Professor in the Department of Geological Sciences. Her research seeks to understand tectonics and sediment processes on and beneath the seafloor. In particular, she investigates submarine earthquakes and landslides, which can present hazards to human life and infrastructure. She is also interested in the geologic aspects of ecosystems and how geology can impact seafloor habitats, which is important for ecosystem risk assessment and preservation. Jillian received her B.S. from the University of Southern California and her Ph.D. from Scripps Institution of Oceanography. Prior to arriving at SDSU, she was a postdoctoral researcher at Louisiana State University, studying seafloor landslides on the subaqueous Mississippi River Delta.
Our lab uses geophysical tools to study geology underwater. These tools include swath bathymetry, sidescan sonar, and sub-bottom seismic methods that can be towed from small boats and larger research vessels. The swath bathymetry and sidescan sonar map the seafloor morphology and roughness, while the sub-bottom seismic data image the sediment and rock layers beneath the seafloor. We also collect sediment cores to ground-truth the geophysical data, obtain ages of sediment layers, and to measure sediment properties such as grain size. In general, we use these data to study: • Sequence stratigraphy and sediment processes • Neotectonics, paleoseismology, earthquake hazard • Subaqueous landslides • Coastal geomorphology • Geologic controls on habitats Current research projects include: 1. Archaeological and biological assessment of submerged landforms on the Pacific Coast 2. Mass wasting processes and products of the Mississippi delta front: Data synthesis and observation 3. Paleoseismic investigation of the Rose Canyon fault zone, San Diego, CA
