Steven Brown, Ph.D.

Dr. Steven Brown earned his B.S. in nuclear engineering from the University of Florida and his Ph.D. from the University of Michigan. At H3D, he works on gamma-ray imaging systems and algorithms for nuclear security, defense, and other applications. He currently leads DOD- and DOE-funded projects to develop gamma cameras for nuclear materials characterization, mobile imaging, and CZT-based PGAA.

David Goodman, Ph.D.

Dr. David Goodman earned his BSE, MSE, and Ph.D. at the University of Michigan. As a Research Engineer at H3D, Inc., his work focuses on a wide variety of topics ranging from isotope identification and nuclear coolant trending to fast, computational-efficient 3-D gamma-ray imaging. He currently leads a Phase II DOE SBIR to develop hot cell-capable CdZnTe imaging spectrometers.


H3D, Inc. is an upstart radiation detection company that develops and manufactures 3-D pixelated CdZnTe spectrometers.

These spectrometers fit into the “goldilocks zone” between HPGe and scintillator detectors, offering better than 1% FWHM energy resolution in a rugged, room-temperature package. The “3-D” nature of pixelated CdZnTe detectors, where a 6 cm3 crystal is subdivided into nearly 5000 subdetectors, also enables gamma-ray imaging.

We will present H3D’s recent progress on DOD and DOE research ranging from isotopic monitoring of commercial nuclear power plants to high-resolution, 3-D imaging, as well as discuss the process of transferring new research ideas to real-world products.
