Dr. Baer is EMSL's science theme lead for Molecular Transformations. As lead he implements the vision for development and implementation of scientific leadership within that area of emphasis, including objectives, targets and assembling the necessary team and resources.
He is internationally known for the application of surface analysis methods to examine corrosion processes and the reactive properties of oxide and mineral surfaces. Since joining PNNL, he has specialized in the use of surface sensitive techniques to study surface and interphase reactions and material surface chemistry. Experienced in using Auger electron spectroscopy, x-ray and ultraviolet photoelectron spectroscopy, secondary ion mass spectrometry, Rutherford backscattering spectroscopy, nuclear reaction analysis, and particle induced x-ray emission, recent research also involves atomic force to examine and create nanoscale features on surfaces.
Dr. Baer's interest in nanoscience and nanotechnology extends to the characterization and reactivity of nanoparticles. He has published more than 260 peer-reviewed journal articles and is internationally recognized for using a wide range of surface sensitive and other methods to understand behaviors of nanoparticles (e.g. ceria, silver and iron core-shell), corrosion processes, and the reactive properties of oxide and mineral surfaces in aqaueous environments.
