Knowledge of the speed of sound in these materials is required to accurately predict a materials stress to strain relationship as a function of frequency. The speed of sound can often be frequency dependent and we are working to measure these dependencies using ultrasonic techniques. The selected student will work with their mentor to measure the dispersion relations and elastic constants of piezoelectric materials using pulse and resonant ultrasound spectroscopy techniques. They will gain experience in computational data analysis, automated measurements with instrument control, and hands-on experiment design.

To be specific, the existing measurement precision is inadequate to differentiate the performance of radio communication frontend chips in noise-sensitive applications. This led GlobalFoundries, a US-based semiconductor manufacturer, to write an open letter to NIST asking for help on this problem. In order to compete globally, US semiconductor chip makers need high-precision on-wafer measurements of microwave noise parameters. This is the set of metrics used to characterize transistors for highly sensitive receivers, and to prove their performance for integration in commercial products. NIST is in the process of developing a new instrument for noise measurements to address this challenge.

And, in that image, they often need to extract and compute statistics of coherent patterns or structures to compare and contrast pairs of pictures. We'll be working in-person with scientific computing and geometric methods applied to broad computer vision challenges such as solar ultraviolet imaging (SUVI) of the sun, electron backscatter diffraction (EBSD) of materials like lithium-ion batteries and steel, as well as x-ray computed tomography (xCT) of silicon chip packages. The position requires a candidate curious to explore some or all of the following topics in applied mathematics: (i) image segmentation and morphology, (ii) abstractions of calculus over curves and surfaces, (iii) topological data analysis, and (iv) implementations/comparisons with generative models. Familiarity with linear algebra and computational geometry is very helpful. Exceptional candidates will also have some experience with introductory real analysis and algebraic topology.

The Fluid Characterization Group (647.07) at NIST is building the foundational science to support deployment of roadside cannabis breathalyzer technology. Some of these commercial breath devices rely on the capture of cannabis particles upon the use of impaction filters –i.e., the inertia of particles drives them to collide with the surface of a filter, which can then be collected.
