Biography

Kayte Denslow is a senior research scientist at Pacific Northwest National Laboratory (PNNL) in Richland, Washington. Denslow has an MS in chemistry from Washington State University and 23 years of experience developing and evaluating technology for ultrasonic non-destructive evaluation (NDE), ultrasonic fluid process monitoring, and high-power ultrasonic processing of fluids. She is a co-developer of commercialized and licensed acoustic technology for noninvasive container inspections and acoustically enhanced coal liquefaction.

Today, she leads a test and evaluation project at PNNL to verify and qualify new robotic ultrasonic NDE technology designed for the volumetric examination of buried nuclear waste tanks at the Hanford site. She is also the principal investigator on a project that is using machine learning, natural gas pipeline data, and existing corrosion rate models to develop a hybrid "data-driven/physics-based" model of pipeline degradation, which can be used to support estimates of remaining useful life and inform preventive maintenance decisions that reduce unforeseen natural gas pipeline incidents.
