Aaron M. Goldfain (Fed)
Aaron Goldfain is an applied physicist in the Surface and Interface Metrology Group in Gaithersburg, MD. He is interested in using light scatter to characterize particles and surfaces and in developing quantitative, label-free imaging methods.
He is currently co-leading a project to develop new light-scattering-based microscopy techniques to characterize nanoparticles. This project aims to speed the development of new gene therapy treatments and improve their efficacy and safety by providing novel, multi-attribute physical measurements (e.g. mass, size, concentration, composition) of gene delivery nanoparticles at the single particle level.
He is also building a database of the bidirectional reflectance distribution functions (BRDF) of materials in the UV/VIS/NIR range. The present focus of this database is the reflectance properties of materials relevant to UV disinfection applications. He is also developing methods for acquiring accurate algae reflectance spectra in the field and helps maintain the NDOSI instrument to characterize diffuse optical materials.
He started at NIST as an NRC Postdoc in the Molecular and Bio-Photonics Group in Boulder, CO. There, he investigated photoacoustic imaging methods and optical methods for ultrasound detection. He received his Ph.D. in Applied Physics from Harvard University where he used interferometric optical microscopy to study the assembly and disassembly of viruses.
