Operating temperature, and hence heat dissipation, impact the performance of energy conversion technologies and electronic devices. Thermal transport in advanced materials for these technologies cannot be described simply by Fourier’s law when the mean free paths of energy carriers are commensurate to feature sizes. Instead, interfaces and non-diffusive transport can govern macroscopic quantities like thermal conductivity. The objective of my research group is to experimentally measure these effects and so to better design and understand these materials. I will begin with an introduction to the nanoscale heat carriers, and I will then present two projects where interfaces influence performance and present methods for . (1) organic-inorganic hybrid materials, and (2) heat assisted magnetic recording (HAMR).

Bio: Jon recieved his Ph.D in Mechanical Engineering at the University of California, Berkeley under the co-advisory of Professors Arun Majumdar (ME, MSE) and Rachel Segalman (ChemE).  He investigated thermoelectricity in single molecule junctions, in an effort to learn more about electronic transport in molecular electronics and organic-inorganic hybrid materials.  Jon received his B.S. in Mechanical Engineering at the University of Michigan, Ann Arbor in 2000 and an S.M. in Nuclear Engineering (2003) from MIT, where he studied transport at the macroscopic reactor scale under the advisory of Professor Neil Todreas.  Since his arrival at Carnegie Mellon in 2009, Jon has received the AFOSR Young Investigator Award (2011), ARO Young Investigator Award (2014), ACS PRF Doctoral New Investigator Award (2011), NSF CAREER Award (2012), ASME Bergles-Rohsenhow Young Investigator Award in Heat Transfer (2014), and the Carnegie Mellon College of Engineering Outstanding Research Award (2016).
