Computational modeling and realtime control of patientspecific laser treatment of prostate cancer
(200805)Hyperthermia based cancer treatments delivered under various modalities have the potential to become an effective option to eradicate the disease, maintain functionality of infected organs, and minimize complications and ... 
Computing accurate solutions to the KohnSham problem quickly in real space
(201408)Matter on a length scale comparable to that of a chemical bond is governed by the theory of quantum mechanics, but quantum mechanics is a many body theory, hence for the sake of chemistry or solid state physics, finding ... 
Controlled selfassembly of charged particles
(201005)Selfassembly is a process of nonintrusive transformation of a system from a disordered to an ordered state. For engineering purposes, selfassembly of microscopic objects can benefit significantly from macroscopic guidance ... 
Coupled flow systems, adjoint techniques and uncertainty quantification
(201208)Coupled systems are ubiquitous in modern engineering and science. Such systems can encompass fluid dynamics, structural mechanics, chemical species transport and electrostatic effects among other components, all of which ... 
Data assimilation for parameter estimation in coastal ocean hydrodynamics modeling
(201312)Coastal ocean models are used for a vast array of applications. These applications include modeling tidal and coastal flows, waves, and extreme events, such as tsunamis and hurricane storm surges. Tidal and coastal flows ... 
Datadriven reduction strategies for Bayesian inverse problems
A persistent central challenge in computational science and engineering (CSE), with both national and global security implications, is the efficient solution of largescale Bayesian inverse problems. These problems range ... 
Datascalable Hessian preconditioning for distributed parameter PDEconstrained inverse problems
(20190621)Hessian preconditioners are the key to efficient numerical solution of largescale distributed parameter PDEconstrained inverse problems with highly informative data. Such inverse problems arise in many applications, yet ... 
Detecting software architecture deviations in development workflows
(201512)Software architectures are carefully designed with desirable qualities for software products, but they are often changed as code implementations evolve over time. If changes are not monitored and repaired, then a software ... 
Development of a multiphysics model for blood flow and drug transport with application to patientspecific coronary artery flow
(200705)A multiphysics model of blood flow and drug dispersion has been constructed for a section of coronary artery. Using NURBSbased isogeometric technology to describe the geometry, I model the release of a liquid drug into ... 
Discontinuous Galerkin (DG) methods for variable density groundwater flow and solute transport
(201212)Coastal regions are the most densely populated regions of the world. The populations of these regions continue to grow which has created a high demand for water that stresses existing water resources. Coastal aquifers ... 
Discontinuous Galerkin finite element methods applied to twophase, airwater flow problems
(2005)A set of discontinuous Galerkin (DG) finite element methods are proposed to solve the airwater, twophase equations arising in shallow subsurface flow problems. The different timesplitting approaches detailed incorporate ... 
Discontinuous Galerkin methods for Boltzmann  Poisson models of electron transport in semiconductors
(201608)The work presented in this dissertation is related to several lines of research in the area of Discontinuous Galerkin (DG) Methods for computational electronic transport in semiconductor devices using Boltzmann  Poisson ... 
Discontinuous Galerkin methods for reactive transport in porous media
(200308)Four discontinuous Galerkin (DG) methods, OdenBaumannBabuˇska DG (OBBDG), Nonsymmetric Interior Penalty Galerkin (NIPG), Symmetric Interior Penalty Galerkin (SIPG) and Incomplete Interior Penalty Galerkin (IIPG), are ... 
Discontinuous Galerkin methods for spectral wave/circulation modeling
(201308)Waves and circulation processes interact in daily wind and tide driven flows as well as in more extreme events such as hurricanes. Currents and water levels affect wave propagation and the location of wavebreaking zones, ...
