Rate My Professor Joshua Cohn

Cohn's research centers on low-temperature electronic, magnetic, and thermal properties of novel materials exhibiting potential for future electronic devices, including thermoelectric effects, spin-mediated heat transport, superconductivity in low-dimensional systems, and thin-film heterostructures. His laboratory utilizes techniques such as pulsed-laser deposition and magnetron sputtering for thin films, x-ray crystallography for structural analysis, and measurements in liquid helium and high magnetic fields. He has obtained major funding from the Department of Energy Basic Energy Sciences, National Science Foundation, and Research Corporation. Key publications include 'Semiconducting Ge clathrates: Promising candidates for thermoelectric applications' (Applied Physics Letters, 1998), 'Glasslike heat conduction in high-mobility crystalline semiconductors' (Physical Review Letters, 1999), 'Giant Nernst Effect and Bipolarity in the Quasi-One-Dimensional Metal, Li_{0.9}Mo_6O_{17}' (Physical Review Letters, 2012), and 'Superconductivity at carrier density 10^17 cm^{-3} in quasi-one-dimensional Li_{0.9}Mo_6O_{17}' (Physical Review B, 2023). With over 6,000 citations and an h-index of 35, his contributions have advanced understanding in condensed matter physics. Awards include the American Physical Society Outstanding Referee (2009), University of Miami Provost Research Award (2011), and Bertman Prize in Physics (1983). He has mentored four postdoctoral fellows, eight Ph.D. students, and thirteen undergraduates, and co-edited proceedings for University of Miami superconductivity conferences.
