Co-founder and CEO of ThinTherm, LLC and a Senior Scientist in the Department of Mechanical and Aerospace Engineering at the University of Virginia. John has conducted research characterizing the mechanical, optical and thermal properties of materials since 2005.
John received his Ph.D. in Mechanical and Aerospace Engineering from the University of Virginia in 2013. His work developed methodologies for testing the size dependent properties in thin film structures. After his Ph.D. John joined Patrick Hopkins group as a post-doc, followed by a position as a Senior Scientist, extending his Ph.D. work focussed on mechanical property characterization to optical and thermal properties.
John’s current research focuses on development of novel optical based non-contact non-destructive thermal characterization tools. His specific interests lie in bridging the divide between neighboring disciplines by incorporating external fields, namely external heat sources, electrical bias, and a variety of reactive atmospheres, during property measurements. Extension of traditional visible based pump-probe techniques to IR wavelengths is a current development project which allows for direct probing of material properties (traditional methods make use of a metallic optical transducer) and dictates lower sensitivity to surface roughness, another limitation of traditional pump-probe techniques.
