Rate My Professor Jamie Warner

Warner’s research centers on nanostructured materials for electronic, opto-electronic, and energy applications, utilizing aberration-corrected transmission electron microscopy and spectroscopy to investigate atomic-level structures and dynamics, complemented by tools such as SEM, AFM, and FIB. Focus areas encompass 2D crystals (graphene, BN, MoS2, WS2), 1D nanotubes, 0D quantum dots, and energy storage materials like batteries, including in-situ electrochemistry studies. He has produced over 325 peer-reviewed publications—170 as corresponding author—in leading journals including Science, Nature Materials, Nature Nanotechnology, Nature Communications (x3), Nano Letters (x16), Advanced Materials (x4), and ACS Nano (x60+), achieving an h-index of 69 and more than 18,500 citations. Key works include “Atomic Structure and Defect Dynamics of Monolayer Lead Iodide Nanodisks with Epitaxial Alignment on Graphene” (Nature Communications, 2020), “Controlling Defects in Continuous 2D GaS Films for High Performance Wavelength-Tunable UV-Discriminating Photodetectors” (Advanced Materials, 2020), “Spatially Controlled Fabrication and Mechanisms of Atomically Thin Nanowell Patterns in Bilayer WS2” (ACS Nano, 2019), and “Atomic Electrostatic Maps of 1D Channels in 2D Semiconductors using 4D Scanning Transmission Electron Microscopy” (Nature Communications, 2019). Notable honors comprise the ACS Nano Lectureship (2019) and Fellowship of the Royal Society of Chemistry (2019). Warner’s leadership elevates UT Austin’s prominence in clean-energy storage, water purification, and quantum technologies.
