The structure lab at ISU is looking for a graduate student at the MS level to join the team in 2022. If you are interested in working on an experimental approach to tackle problems related to friction and motion of faults, contact Jacqueline Reber via email (email@example.com). We are a welcoming and dynamic group that … Continue reading Seeking applicants for 2022!
Lab member Emily Ross was awarded a 2020 AGU Outstanding Student Presentation Award for her talk titled “Off-Fault Deformation Due to Changes in Slip Dynamics on the San Andreas Fault: An Experimental Approach.” You can watch her talk here:
Kyle Bogatz recently defended his Master’s Thesis titled, “Deformation of brittle clasts within a viscous matrix: field and experimental observations.” Kyle leaves us after many years, first as an undergraduate researcher and followed that up with his Master’s work. Kyle’s project combined field work at the Papoose Flat Pluton in California and some preliminary lab … Continue reading Congrats Kyle!
The Structure Lab has a new paper in press titled The effect of a liquid phase on force distribution during deformation in a granular system. Look for it in the Journal of Geophysical Research – Solid Earth. https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/2020JB019771 Abstract Two‐phase systems, where one phase is solid and the other fluid, are widespread in nature. Examples … Continue reading New paper in press!
The Structure Lab congratulates Claire Ruggles for successfully defending her Masters Thesis titled, A multiple-pulse emplacement model for the Shonkin Sag laccolith, MT. Claire will be moving on back to the University of Wisconsin to begin her pursuit of a Ph.D. We will miss you!
Now accepting applications for the Geol 406/506 course to Portugal! The field trip will depart Des Moines on Jan. 1st, 2021 and we will arrive back Jan. 10 in time for the start of the semester. The field trip will be led by Dr. Jacqueline Reber and Dr. Al Wanamaker. More information can be found … Continue reading Structures, Caves, and Coasts Field Trip | Portugal 2021
The Structure Lab would like to congratulate Chris Ladd for successfully defending his Masters Thesis titled “An experimental analysis of force distribution in a two-phase system.” Chris has presented his work at AGU in 2019 and 2018, as well as the 2018 NC GSA Regional Meeting. Chris originally entered Iowa State in 2012 as an … Continue reading Congratulations Chris!
Nearly 2 years after its conception, the Structure Lab’s ring shear device is up and running. The soothing green glow is from a laser sheet illuminating brittle polymer spheres surrounded by viscous gel. Kyle Bogatz is conducting experiments on processes of grain fracturing in semi-brittle material (picture feldspar clasts in a semi-brittle granitoid). This represents … Continue reading Ring shear device up and running!
Congratulations to Dr. Jacqueline Reber, assistant professor in geology, who has been awarded a National Science Foundation 2019 Faculty Early Career Development (CAREER) award, one of the NSF’s most distinguished awards. The 5 year award supports Dr. Reber’s research on “Combining physical and numerical modes to characterize the contribution of semi-brittle rheology for deformation dynamics … Continue reading Jacqueline Reber earns NSF CAREER award
Everyone at The Structure Lab would like to congratulate Jeremy Randolph-Flag for successfully defending his Master’s thesis: Experimental analysis of the effect of grain size distribution on stick-slip and creep behavior. While working in the lab, Jeremy presented his findings at both the 2018 GSA regional meeting in Ames and the 2017 national meeting in … Continue reading Congratulations Jeremy!
