Dr. Cooksey’s laboratory at NIST focuses on creating microfluidic tools to improve measurements and enable discoveries in biomedical and clinical research. His group is developing new approaches to measure optical properties of cells and materials in flow, and applications related to cytometry.
The group recently published the first direct uncertainty measurements in flow cytometry, which required novel flow control and analysis techniques in microfluidic devices with integrated waveguides. Work with collaborators in the Information Technology Laboratory is using signals analysis to improve counting, classification, and understanding of physical properties (e.g. size and shape) of objects in flow.
The team continues to improve accurate measurements of volumetric flow rates, recently demonstrating dynamic measurements of 1 nL/min with 5 % uncertainty and limit of detection of about 10 pL/min. The technique involves linking fluorescent properties of materials to the dosage of light they receive while flowing through an optical interrogation region.
These projects are part of the NIST on a Chip program and are supported by a NIST Innovation in Measurement Science (IMS) award.
Greg Cooksey joined NIST in 2007 as a National Research Council postdoctoral fellow and is a biomedical engineer and Project Leader in the Microsystems and Nanotechnology Division. Prior to NIST he was a graduate student and postdoctoral researcher at the University of Washington, where he developed surfaces and devices to study migrating cells and neurons.
