Biography

Dr. Whalen received his PhD from Washington State University in 2004 where he developed the world’s first, and still only, engine to ever to be fabricated on a silicon chip and shown to run on a thermodynamic working cycle. After graduation, he completed a post-doctoral appointment at Sandia National Laboratories investigating micro-scale thermoelectric materials and devices. As a staff scientist at Sandia, Dr. Whalen performed R&D on all aspects of plutonium and tritium-based thermoelectric systems and materials. Dr. Whalen joined PNNL in 2012 where he now investigates solid-phase processing techniques to achieve novel microstructures and improved material properties that cannot be realized by conventional means. Areas of particular interest include extrusion of lightweight structural metals, joining of dissimilar materials and fabrication of nanocomposites in bulk form.
