Educational Background
Biography
Dr. Joshua L. Knobloch is an Assistant Professor in the Department of Physics at Utah State University. He received his B.S. degree in physics and mathematics from Purdue University (2014). And, he received his M.S. (2018) and Ph.D. (2020) in physics from the University of Colorado Boulder under the advisement of Profs. Margaret Murnane and Henry Kapteyn. From 2020-2024, he was a postdoctoral associate and then a senior research associate at JILA—a joint research institute between the Department of Physics at the University of Colorado Boulder and NIST Boulder. He has received multiple awards for his educational and research success including the Purdue College of Science Most Outstanding Physics Student for three consecutive years, the Semiconductor Research Corporation Education Alliance/Intel Graduate Research Fellowship, and the graduate Student Presentation Award at TECHCON. His current research focuses on observing and predicting novel energy transport behaviors in nanostructured materials using unique ultraviolet tools for applications in next-generation nanoelectronics and novel energy technologies. His work has been published in journals including PNAS, Science Advances, ACS Nano, and Nano Letters with one publication receiving a top 5% ‘attention score’ and featured in several news outlets including Denver7 News on ABC.
Teaching Interests
Dr. Knobloch enjoys teaching physics classes at all levels. He is especially interested in the subject areas of thermal, statistical, solid-state, and material physics in addition to waves, electricity and magnetism, optics, and nanoscale energy transport
Research Interests
Dr. Knobloch's research focuses on cross-disciplinary efforts to gain fundamental insights into condensed matter and material physics by using state-of-art ultrafast, short-wavelength lasers. His current research directions include building new ultrafast, ultraviolet spectroscopies to understand novel nanoscale energy transport behaviors and to measure the functional properties of new materials for applications in next-generation nanoelectronic, quantum, and energy technologies.
