Projects and Programs

Standards Development to Ensure Reliable Breath Analysis in the Field

Ongoing

Numerous volatile organic compounds (VOCs) have been identified in human breath. These compounds can be produced by the body or by organisms in the body (e.g., bacteria or viruses) and provide a non-invasive window into human health. Inexpensive point-of-care devices are being developed to diagnose

Statistical Support for Bioassay Standard Development

Ongoing

Biological assays are procedures that can determine concentration, purity, or biological activity of a substance through scientific experimentation. Fluorescence-based quantification one of the most widely used technique in quantitative clinical and biochemical assays, and it depends on the

Face Recognition Prize Challenge 2017

Ongoing

Results From June to September 2017, NIST evaluated 41 face recognition algorithms from 16 developers. The algorithms were applied to datasets of 2D still photographs in two ways: verification of “wild” photojournalism and social media images, and identification of faces from surveillance videos

Using Geodesics in Cell Cytometry

Ongoing

This project involves image cytometry, mathematics and statistics. Understanding cellular responses to stimuli, such as pharmaceuticals or environmental toxins and discovering correlations between cellular responses and the cell phenotype are applications motivating this work. Change in shape is a
