Dr. Rolfe specializes in failure analysis and materials characterization and processing, focusing particularly on the micro- and nano-scale. He has over 4 years of research experience focusing on materials processing and microfabrication. He has additional experience in the design and fabrication of extreme-environment sensors and actuators.
Prior to joining Exponent, Dr. Rolfe conducted his Ph.D. research at the University of California, Berkeley, under the supervision of Professor Albert P. Pisano. His research focused on novel techniques for the fabrication of micro- and nano-scale conductive patterns using metal nanoparticle inks. Through this work, Dr. Rolfe gained familiarity in microfluidics, permeable membranes, lithography, polymer synthesis and processing, and laser etching and transfer. He also has experience in scanning electron microscopy (SEM), white light and infrared interferometry, laser and optical confocal microscopy, thin film reflectometry, and surface profilometry. For his master’s work, Dr. Rolfe developed a silicon carbide flame sensor for in-situ engine monitoring. Prior to that, he developed a piezoelectric motor to be used at ultra-low temperatures for the Axion Dark Matter Experiment.
While at UC Berkeley, Dr. Rolfe was a teaching assistant for an introduction to engineering laboratory class focusing on rapid prototyping and mechanical testing. He consulted for the West Contra Costa County School District, advising on rapid prototyping curricula for secondary school students. Dr. Rolfe has also collaborated with ethicists and other engineers to research ethical frameworks and education for nanotechnology researchers.
