Research highlight

    Broadly speaking my work relates to computational modeling of un/bonded or un/consolidated granular materials. This includes: matrix-skeletal stress analysis, nonlinear material softening/equations of state (as below), as well as coupled fluid flow modeling.

    Rate Jump

    Fig. 1. Isothermal Dieterich-Ruina friction coefficient models, showing jumps in slip rate: (a) the original relation of Ruina and (b) the completed slowness relation.

    Temp Jump

    Fig. 2. Temperature-dependent Dieterich-Ruina friction coefficient models, showing jumps in temperature: (a) the original relation of Ruina modified for temperature dependency by Chester and (b) the completed slowness relation modified for non-isothermal conditions.

 Educational Background/Employment:
  • 2020 - Present : CNLS Postdoctoral Research Associate, Los Alamos National Laboratory
  • Ph.D., Civil Engineering (2020) Presidential/Guggenheim Fellow and G/DRA for W. Sun, Columbia University
  • M.S., Petroleum Engineering (2016) GRA for M. Sharma, University of Texas at Austin

Research Interests:

  • Micromorphic continua formulations for solids deforming in the brittle/ductile regimes, derived by homogenizing un/bonded inter-granular contact interactions.
  • Thermoplastic frictional contact along fracture surfaces represented with implicit functions; mixed-mode and hydraulically-induced fracture.
  • Strain- and projected-strain-space mappings to numerically capture materials' fabric and mesostructural anisotropies, respectively.
