CUSSP Early Career Network
CUSSP is committed to recruiting and developing the next generation of multidisciplinary scientific leaders. The CUSSP Early Career Network (ECN) provides resources and opportunities for researchers growing their careers.
The founding director of the CUSSP ECN is MJ Abdolhosseini Qomi with the University of California, Irvine. The early career researchers are represented by Tom Underwood, a postdoctoral research associate at Pacific Northwest National Laboratory.

Institute while in CUSSP: University of Maryland
Job Level: Postdoctoral Research Associate
Years with CUSSP: 2024-present
CUSSP Mentor: Wenlu Zhu
CUSSP Publications: pending
Research Areas: Performing deformation and micro-CT experiments on selected SURF core samples. Experiments are designed to measure permeability, porosity, electrical conductivity, and velocity of selected core samples for comparison to core-scale measurements. 3-D microtomography data will but used to construct digital rock analogues and perform digital rock physics simulations to obtain permeability and electrical conductivity from in-situ deformation experiments. These results will be used to connect reactive fracture flow and deformation to geophysical signals with the overarching goal is to improve subsurface permeability control at enhanced geothermal fields.
