Dr. Bronstein specializes in optics, nanomaterials, and physical modeling. He has extensive experience creating custom experimental apparatus and optical models to understand light emitting materials and devices, including lasers, LED devices, and color displays. His consulting work to date has focused on optical models and radiometric measurements for eye and skin safety of laser/LED products.

Before joining Exponent, Dr. Bronstein supported the development of carbon nanotube reference materials at the National Institute of Standards and Technology (NIST) by developing a thin-film thermogravimetric analysis technique and statistical data analysis tools. Afterward, his doctoral research at UC Berkeley focused on utilizing first principles to design photovoltaic windows based on semiconductor quantum dots. This effort led to a postdoctoral position at Lawrence Berkeley National Lab, where he solved the problem of high-accuracy photoluminescence quantum yield measurement. Afterward, as a postdoctoral fellow at the National Renewable Energy Lab, he developed nonthermal plasma processes for semiconductor nanomaterial synthesis.

A physical chemist by training, Dr. Bronstein has experience with the following analytical tools:

  • Optical absorption, transmission, and reflectance measurements
  • Fourier-transform infrared (FTIR) and Raman spectroscopy
  • Steady-state and time resolved photoluminescence
  • Nuclear Magnetic Resonance (NMR)
  • Transmission electron microscopy (TEM)
  • Energy-dispersive spectroscopy (EDS)
  • X-ray diffraction (XRD)
  • X-ray absorption fine-structure (XAFS)
  • Capacitance-voltage (C-V) profiling

He also has experience with the chemical techniques associated with:
  • Air-sensitive materials synthesis
  • Pyrophorics
  • Toxic gases
  • Vacuum systems.

And finally, he has extensive knowledge of the following materials systems:
  • Lead-salt perovskites, such as CsPbBr3 and (CH3NH3)3PI3
  • II-VI semiconductors, such as CdSe, CdS, and ZnS
  • III-V semiconductors, such as GaAs, InGaAs, InP, GaP, and InGaP
  • IV-VI semiconductors, such as PbS and PbSe
  • Carbon nanotubes
