Has over 25 years of industry experience including oil and gas, mining and geothermal. Her expertise includes microseismic and earthquake acquisition, processing, interpretation, and data integration across multiple industries. She has worked on tight gas and unconventional oil projects in North and South America, Australia, and Europe and applied surface, borehole, and fiber optic data acquisition methods. Her knowledge includes planning, data processing QC, and interpreting data in microseismic mapping of hydraulic fractures. She was selected to be a member of the National Research Council study on Induced Seismicity published in 2013, and since then, has been actively involved as a consultant to regulators and oil and gas operators on induced seismicity issues. She is an expert user of the Transform software platform, and was involved in the application's development. As an expert witness, she has testified on a variety of subjects, including cases related to hydraulic fracturing "frac hits", solution mining cavern failure, and land conflicts. Julie was a member of Society of Exploration Geophysicists (SEG) The Leading Edge Editorial Board from 2014-2017, serving as Chairman in 2017.
