Chris Marone - Marone’s research focuses primarily on earthquake physics, friction, and fault mechanics. Recent themes have included: 1) rate-state friction mechanics, fault healing and the application of laboratory derived friction laws to the spectrum of fault slip behaviors, 2) poromechanical properties of deforming rocks, 3) the role of dynamic stressing in frictional instability, 4) granular mechanics and the effect of particle properties on friction, jamming and unjamming, and 5) the role of shear fabric and clay mineralogy on the frictional strength and constitutive properties of fault rocks. | Website

Demian Saffer - Dr. Saffer's research centers on (1) quantifying the role of fluids in geologic processes at the scale of the Earth’s crust, with a primary focus on fluid pressure, fluid flow, and fault physical properties along plate tectonic boundaries; and (2) understanding rock and fault zone deformation behavior, mechanical strength, and hydrologic properties. To investigate these processes, I combine laboratory measurements, computer-based numerical modeling, and field data collection. As part of these research efforts, my group is heavily involved in a range of scientific drilling projects to investigate plate boundary faulting; these include participation in the San Andreas Fault Observatory at Depth (SAFOD) and continental drilling to sample across the active Alpine Fault in New Zealand, and and a leadership role in several Integrated Ocean Drilling Program (IODP) projects to drill offshore of Japan and New Zealand to study earthquakes, including the high slip area of the 2011 Tohoku M9 event, and slow slip along subduction megathrusts. | Website
Derek Elsworth - Derek's interests are in the areas of computational mechanics, rock mechanics, and in the mechanical and transport characteristics of fractured rocks, with application to geothermal energy, the deep geological sequestration of radioactive wastes and of CO2, unconventional hydrocarbons including coal-gas, tight-gas-shales and hydrates, and instability and eruption dynamics of volcanoes. | Website
Eliza Richardson - Eliza is an earthquake seismologist who studies slow slip events in subduction zones, volcano-earthquake interactions and induced seismicity. She is also involved in some other projects including educating rural adults about all sides of shale gas extraction activities and impacts, learning progressions in children, cognition biases in geospatial intelligence analysis, and baseball. She is the lead faculty member for PSU's M.Ed. in Earth Sciences program which is a master's degree program aimed at mid-career high school science teachers. | Website
Shimin Liu - Shimin Liu joined Penn State as an Assistant Professor in 2013 after completing his Ph.D. from Southern Illinois University. His expertise is in gas storage and transport mechanism in coalbed methane reservoirs and carbon sequestration in geological formations, especially in the areas of laboratory characterization of gas-coal interaction, analytical modeling of gas transportation under in situ conditions for carbonaceous rocks, volumetric behaviors of coal with gas adsorption/desorption, CO2 sequestration in coal seams and enhanced gas production. | Website
Jacques Rivière - Assistant Professor of Engineering Science and Mechanics. Research Interests: Ultrasonics; Geophysics; Nonlinear acoustics; Vibrations; Nondestructive testing of materials; Structural health monitoring; Material characterization and damage assessment; Friction | Website
Parisa Shokouhi - Associate Professor of Engineering Science and Mechanics. Research interests: Stress wave propagation in fractured media, Nondestructive evaluation (linear and nonlinear ultrasonic testing), Structural health monitoring (acoustic emission), Machine learning and data analytics, Seismic metamaterials | Website
Steven Swavely - Steve is responsible for maintaining the laboratory equipment and helping us develop new equipment. Steve works with our electrical systems, building electronics, hydraulic and high pressure pump service, and works with the machine shop. Our lab has a very active group that continually devleops new techniques and needs technical support. Our systems also require regular maintence, calibration, and development. In addition, an inventory of equipment and small parts is maintained, safety paperwork kept updated, and lab purchaching is done through Steve.

Tim Witham - Tim earned his bachelor's from the University of Tulsa's Geoscience program in 2017. He is indebted to the faculty and alumni community there, who named him an Outstanding Senior upon graduation. His research interests include fracture propagation and ultrasonic monitoring techniques. While at Penn State, Tim was a member of the 2018 IBA team, which won 3rd place at the international stage. When not in the lab, he enjoys birdwatching, reading and writing short stories, and watching movies. | Website
