Expertise

  • Mudunuru’s primary research interest is on predictive modeling of coupled flow and reactive-transport with mechanical deformation in surface and subsurface systems. His emphasis is to develop mechanics, mathematical models, and numerical techniques to understand (steady-state and transient) multi-scale phenomena in heterogeneous deformable media.
  • His current research interests include (1) developing mathematical models with firm thermo-mechanical underpinning (2) developing reduced-order models (based on dominant coupling mechanisms/processes) using machine learning and dimensionality reduction methods (3) developing fast and robust computational frameworks for inverse problems to determine data-to-decision strategies for contaminant transport, bioremediation, structural health monitoring, and identification of geothermal prospectivity, and (4) performing predictive simulations to address scientific questions relevant to LANL’s mission, and solve practical problems using high-performance computing tools.
  • Mudunuru’s main application areas include geosciences (contaminant transport, groundwater hydrology, enhanced geothermal systems, environmental remediation, and induced seismicity), material damage (degradation and healing of geomaterials, infrastructural materials such as cementitious and asphaltic materials, and composites), and damage sensing and prognosis of subsurface, civil, and mechanical systems.
