Jonathan Malen seeks fundamental understanding of thermal transport processes from atomistic to macroscopic scales in advanced materials and technologies. The Malen Laboratory leverages ultrafast laser techniques, micro/nanofabrication, and thermal imaging approaches to measure thermal properties and processes. Recent projects are related to thermal management in high powered electronics (e.g. GaN and Ga2O3), thermal imaging in advanced manufacturing processes, evaporative cooling in nanoscale menisci, and phonon transport in organic-inorganic materials (e.g. superatomic crystals, organic perovskites, liquid metal composites).

Malen is a recipient of the Benjamin Richard Teare Teaching Award (2019) and the David P. Casasent Outstanding Research Award (2016) at Carnegie Mellon, the ASME Bergles-Rohsenhow Young Investigator Award in Heat Transfer, the Army Research Office Young Investigator Award (2014), the National Science Foundation CAREER Award (2012), and the Air Force Office of Scientific Resarch Young Investigator Award (2010). He came to Carnegie Mellon in 2009 after receiving his Ph.D. in mechanical engineering from UC Berkeley (2005-2009), his MS in nuclear engineering from MIT (2002-2003), and his BS in mechanical engineering from the University of Michigan (1996-2000).

Dailymail features “thubber”

MechE’s Carmel Majidi and Jonathan Malen have developed a material that could allow you to fold your iPad so that it fits inside your wallet. The duo’s creation, nicknamed “thubber,” can conduct heat while retaining its elasticity, much like biological tissue.

Majidi and Malen develop Thubber

MechE’s Carmel Majidi and Jonathan Malen have recently made a breakthrough in the field of soft robotics with the development of a thermally conductive, stretchable rubber called “Thubber.” Able to stretch to over six times its length while still remaining conductive, Thubber strikes an unprecedented balance between thermal and mechanical properties in soft dielectric materials and opens the door to high-power, flexible devices.
