Rate My Professor Joshua Cohn

Cohn's research centers on the low-temperature electronic, magnetic, and thermal properties of novel materials exhibiting interesting physics, including quasi-one-dimensional metals, helimagnetic insulators, correlated transition-metal oxides, thin films, and thermoelectric materials. His lab employs techniques such as precise measurements of electrical conductivity, thermal conductivity, and thermoelectric effects on millimeter-sized crystals cooled to cryogenic temperatures, as well as fabrication and analysis of thin films. Key publications include “Ballistic magnon heat conduction and possible Poiseuille flow in the helimagnetic insulator Cu₂OSeO₃” (Physical Review B, 2017; Editor’s Choice), “Spin phases of the helimagnetic insulator Cu₂OSeO₃ probed by magnon heat conduction” (Physical Review B, 2019), “Extreme Thermopower Anisotropy and Interchain Transport in the Quasi-One-Dimensional Metal Li₂Mo₃O₁₀” (Physical Review Letters, 2014), and “Giant Nernst Effect and Bipolarity in the Quasi-One-Dimensional Metal Mo₅Li₃O₁₀” (Physical Review Letters, 2012). With 79 refereed journal articles, his scholarship has earned 6,143 citations and an h-index of 35 according to Google Scholar. Cohn has received the University of Miami 2011 Provost Research Award, the American Physical Society Outstanding Referee award in 2009, and other honors. He serves as Associate Editor for Frontiers in Physics and has co-edited research topics and conference proceedings.
