- David Cahill is the Grainger Distinguished Chair in Engineering and Professor of Materials Science and Engineering at the University of Illinois at Urbana-Champaign. He joined the faculty of the Department of Materials Science and Engineering at the U. Illinois after earning his Ph.D. in condensed matter physics from Cornell University, and working as a postdoctoral research associate at the IBM Watson Research Center. His current research program focuses on developing a microscopic understanding of thermal transport at the nanoscale; extremes of low and high thermal conductivity in materials; the interactions between phonons, electrons, photons, and spin; and the kinetics and thermodynamics of aqueous and electrochemical interfaces with materials. He received the 2018 Innovation in Materials Characterization Award of the Materials Research Society (MRS); the 2015 Touloukian Award of the American Society of Mechanical Engineers; the Peter Mark Memorial Award of the American Vacuum Society (AVS); and is a fellow of the MRS, AVS, APS (American Physical Society), and AAAS. Prof. Cahill received the 2020 Tau Beta Pi Daniel C. Drucker Eminent Faculty Award from the Grainger College of Engineering.
Thermal management is a critical issue in a wide variety of applications of thin films materials from state-of-the-art microprocessors to turbine engines. Heat can be carried by any excitation of the solid that is thermally excited: lattice vibrations, electrons, spin-waves. The lifetime or coherence of these excitations have a complex dependence the microstructure of materials; at nanometer length scales, the transfer of heat between various excitations at interfaces becomes the controlling factor. Our group studies the basic science of thermal transport in materials with a particular emphasis on the exchange of thermal energy at solid-solid and solid-liquid interfaces. We have recently developed new and powerful methods of characterizing nanoscale thermal transport using ultrafast laser metrology of precisely controlled thin film multilayers and suspensions of metallic nanoparticles. We are currently working to extend our experimental methods to higher resolution in time, space, and energy.
