Research:
Ardalan is studying metal-mineral interactions with particular emphasis on the molecular-scale dynamics of interfacial reactions. He is developing reactive molecular dynamics simulations and enhanced sampling methods coupled with advanced in situ spectroscopic techniques to elucidate complex reaction pathways. Ardalan is using this novel approach to examine thermodynamic and kinetic aspects of metal adsorption onto iron (oxyhyd)oxides. |
Research:
Valerie is studying dynamics of metal-mineral interactions with implications for metal mobility in both modern environments and paleoenvironments. Valerie integrates synchrotron techniques, electron microscopy, and experimental approaches to address both fundamental and applied scientific questions with implications for environmental change through geologic time and for mine waste management and site remediation. |
