**About the Special Issue Editor**

**Julia W. P. Hsu** is Professor of Materials Science and Engineering in the Erik Jonsson School of Engineering and Computer Science of the University of Texas at Dallas (UTD) and holds the Texas Instruments Distinguished Chair in Nanoelectronics. She received her B. S. E. degree in Chemical Engineering from Princeton University in 1985 and her Ph.D. degree in Physics from Stanford University in 1991. After a two-year postdoc at Bell Labs, she joined the faculty at the University of Virginia (UVA) as an Assistant Professor of Physics, earning tenure there in 1997. In 1999, she returned to Bell Labs as a Member of Technical Staff. Prior to coming to UTD, she was a Principal Member of Technical Staff at Sandia National Laboratories in Albuquerque NM from 2003 to 2010.

Prof. Hsu's research is in the area of nanoscale materials physics and interfacial phenomena at the interfaces of dissimilar materials. She has done extensive work on the spatially resolved characterization of electronic and photonic materials and devices using scanning probe techniques. The material systems she has studied are wide ranging, including metals and alloys; group IV, III–V, and II–VI semiconductors; polymers; nanocomposites; and oxides. Her work focuses on how macroscopic materials properties or device characteristics are affected by local materials chemistry or materials processing. Her recent research focuses on nanomaterials for optoelectronic and energy applications, including organic photovoltaics, nanomaterial synthesis, solution processing of inorganic nanocrystals and thin films, the synthesis and processing of few-layer transition metal dichalcogenides, electrical and optoelectronic studies of solar cells and transistors, earth-abundant oxides for clean air treatment, and low-temperature high-throughput processing of flexible electronics. Prof. Hsu has published over 200 journal papers, has been granted five patents, and has given over 180 invited talks.

Prof. Hsu is a Fellow of the American Physical Society (APS), the American Association for the Advancement of Science, and the Materials Research Society (MRS). She is a winner of a Hertz Foundation Fellowship, APS Apker Award, a National Science Foundation Young Investigator Award, and a Sloan Foundation Research Fellowship. Prof. Hsu currently serves on Department of Energy Basic Energy Science Advisory Committee. She was an August-Wilhelm Scheer Visiting Professor at Technische Universitat M¨ unchen in 2018 and was recently awarded a Visiting Research ¨ Professorship at the University of Hong Kong. She was an organizer of the TMS Electronic Materials Conference and a co-chair for the Fall 2004 MRS meeting. She served as a Member-at-Large on the APS Division of Materials Physics Executive Committee (2004–2007), on the MRS Board of Directors (2005–2007), as the Treasurer and Chair of Operation Oversight Committee for the MRS (2006–2007), as chair of the MRS International Relations Committee from 2010 to 2011, and is a long-time member of MRS Meeting Assessment Subcommittee. She has held several key committee positions at UVA and UTD, and been on numerous review panels for funding agencies and on external advisory committees for research centers.
