Stephen Kennedy, Ph.D.

Consulting Scientist

Dr. Stephen Kennedy, Consulting Scientist, is an expert in the use of computer controlled scanning electron microscopy (CCSEM) for the characterization of particle composition, size and shape. Dr. Kennedy has applied this tool to the specification of mineral and anthropogenic particulate in soils and dust, including the determination of the abundance, composition, size and shape of heavy metal particles for sourcing, remediation and assessment of potential health effects, both in the context of environmental and industrial forensics. Some of his projects have included: characterizing particulate in buildings damaged by fire, determining the abundance of slag in river sediment, identifying and characterizing potential fatigue crack inducing inclusions and mixed alloys in powder metal to document cleanliness, and assessing powder metal size and shape related to flow behavior of powder used in additive manufacturing.

In addition, Dr. Kennedy has participated in a variety of educational activities, such as outreach, mentoring, and educational module development. He has held several teaching positions, including that of Assistant Professor at the University of Pittsburgh for eight years previous to joining the company. Dr. Kennedy received his Ph.D. in Geology with a specialty in sedimentology from the University of South Carolina. He is the author or co-author of more than 80 publications and presentations and has published in peer-reviewed journals.
