![]() Charlotte Bate, Laboratory Technician, has been working together in the Rock Mechanics Lab since 2019. She manages the lab, supervise research activities, and design/implement new instrumentation. Maciej Trzeciak, Postdoctoral Researcher, was a former visiting student from the Polish Geological Institute in 2016 and 2018. He returned as a postdoc now working on a project developing a technology to measure in-situ stress in boreholes utilizing thermal stresses. He works with the large true-triaxial apparatus with acoustic emission to validate the technology in lab-scale samples. He also started on a project to measure in-situ stress in geothermal reservoirs utilizing cooling-induced fractures in boreholes. ![]() Eril Suhada Lanin, PhD student, holds a MS (2011) and BS (2004) in Geology from Institut Teknologi Bandung (ITB) in Indonesia. Before starting his doctorate study at UW, he was an assistant lecturer at ITB. He also had previous experience working in the industry. He was a Technical Professional Log Analyst at Halliburton and a Petrophysicist/ Operations Geologist at Kangean Energy in Indonesia. His research focuses on mechanical properties, especially creep, of shales. ![]() ![]() Zirou Jin, PhD student, holds a MS (2018) in GLE from UW-Madison, BS (2016) in Applied Geophysics from Central South University in China. She studies geophysical methods as an undergraduate. She is currently focusing on analytical calculation and data inversion on laboratory fault slip data. Specifically, it is on Westerly granite properties during stick-slip cycles and the viscous properties of Nankai accretionary prism material undergoing stress accumulation. Benjamin Jahnke, MS student, BS in GLE from UW-Madison (2020). His research focuses on the characterization of elastic properties and fracture toughness of Yates Amphibolite and Rhyolite dike rocks found at the 4100 level of Homestake Mine, SD, for the EGS-Collab project led by LBNL. Ben is also involved in the WHOLESCALE project characterizing the stress state from geophysical data in a geothermal reservoir in San Emidio, NV. Ben will also conduct laboratory experiments to characterize the frictional properties of reservoir rocks in San Emidio. Porter Garts, Undergraduate Researcher, is in his second year of his BS in Geological Engineering. He is working on tensile strength measurements of Yates Amphibolite and Rhyolite rocks found at the 4100 level of Homestake Mine, SD, for the EGS-Collab project.
