Physicist
Research Interests
Method development in the field of X-ray Absorption Spectroscopy (XAS) and related inner-shell spectroscopies, including development of novel measurement techniques and detector technologies
Development of software tools for XAS data acquisition, processing, and analysis
Application of XAS to a wide variety of scientific disciplines. Along with materials science interests in the areas of ferroelectrics and strongly correlated electron systems, I have applied XAS measurements to a wide variety of scientific disciplines, including the environmental sciences, the interpretation of astronomical spectra, the study of objects of cultural heritage, and many others.
Postdoctoral Research Opportunities
Synchrotron-based X-ray absorption spectroscopy is used in conjunction with novel theory and analysis methods to develop, understand, and optimize materials for microelectronics, catalysis, energy science, and other fields. Materials that can be investigated cover all forms of condensed matter from monolayer films to the bulk, from crystalline to highly disordered. These studies offer the opportunity to develop and utilize world-class X-ray instrumentation and detectors.
Professional Service
Member of the IUCr Commission on XAFS, 2014-2023
Chair of the spectroscopy Proposal Review Panel for NSLS-II. Member of proposal review panels for synchrotron facilities worldwide, including the Stanford Synchrotron Radiation Laboratory (SSRL) and the Cornell High Energy Synchrotron Source (CHESS), SPring-8 in Japan, Elettra in Italy, the Canadian Light Source, and SESAME in Jordan.
We propose a standard data format for the interchange of XAFS data. The XAFS Data Interchange (XDI) standard is meant to encapsulate a single spectrum of XAFS
The analysis of EXAFS data measured on a material with a disordered local configuration environment around the absorbing atom can be challenging due to the
