Research Interests

  • Spatiotemporal behavior in chemisorption and catalysis on metal surfaces: realistic atomistic-level modeling of reaction kinetics; analysis of chemical diffusion and multi-scale modeling of reaction-diffusion behavior; analysis of fluctuations in nanoscale systems.
  • Fundamental statistical mechanical studies of far-from-equilibrium reaction-diffusion phenomena including kinetic phase transitions.
  • Interplay between anomalous transport and reaction in catalytically-functionalized mesoporous and nanoporous materials.
  • Self-assembly and stability of single- and multi-component epitaxial metal nanostructures formed by deposition on single-crystal surfaces.
  • Growth and relaxation epitaxial thin films: submonolayer nucleation & growth of islands; multilayer kinetic roughening; post-deposition coarsening; step flow during growth and erosion.
  •  

    Selected Projects

  • Realistic multi-site lattice-gas models for CO-oxidation on Pd(100), Rh(100), Pt(100), and other surfaces.
  • Heterogeneous-coupled-lattice-gas modeling of patterns and fronts in catalytic surface reactions (HCLG is our Heterogeneous Multiscale Method).
  • Statistical mechanical analysis of discontinuous poisoning transitions (including generic two-phase coexistence and metastability) in reaction-diffusion models.
  • Modeling of catalytic conversion reactions and polymerization reactions in nanoporous systems with single-file diffusion.
  • Continuous-random-network models structure of amorphous materials (e.g., mesoporous oxide catalysts).
  • Formation of epitaxial nanostructures by deposition on a NiAl(110) binary alloy substrate, including analysis of alloy self-growth.
  • Effect of chalcogen additives (S, O) on stability of noble metal surface nanostructures (including additive-enhanced coarsening and cluster mobility).
  • Predictive atomistic and coarse-grained modeling of homoepitaxial thin film growth (for both submonolayer and multilayer regimes).
  • Development of general multi-site lattice-gas models and KMC simulation algorithms incorporating precise kinetics (surface diffusion barriers) for epitaxial systems.
