Dr. Zhang was awarded Honorary Docent from Lund University in 2004 after a rigorous evaluation of scientific achievements and pedagogical skills. Since 2006, she has held a guest professor appointment at Peking University (China), where she supervises graduate students in the field of materials research. She currently has served as a member of the Advisory Editorial Board for Nuclear Instruments & Methods in Physics Research, Section B since 2009. Dr. Zhang joined Oak Ridge National Laboratory in June 2010 with a joint faculty appointment in the Department of Materials Science and Engineering at the University of Tennessee.
Dr. Zhang’s notable experience and accomplishment over the years is highlighted by her publication record, which includes more than 130 journal articles (lead author on 57), and 15 peer-reviewed conference papers. She is an author of an invited chapter: MeV Ion beam Modification of Materials in the book Electrostatic Accelerators – Techniques and Applications, and is a co-editor for a book on Ion Beams in Nanoscience and Technology. She has given more than 70 presentations at universities, research institutions, scientific conferences and workshops, including 35 invited presentations. In recognition of her professional and personal achievements, community service and exemplary leadership, she was awarded a 2005 Presidential Early Career Award for Scientists and Engineers and DOE Office of Science Early Career Scientist and Engineer Award. Dr. Zhang has organized several society symposia and international conferences, serves as a reviewer for international journals, and has been active in mentoring of students at the high school, undergraduate, graduate and postdoctoral levels.
Dr. Zhang’s research experience covers a range of topics in both theoretical and experimental materials science and engineering. The central aspect of Dr. Zhang’s research has been the interaction of ions and electrons with materials and how these interactions can be applied to the analysis and modification of materials, as well as the detection and characterization of charged particles. Her work has included radiation effects in materials, ionization-induced recrystallization, electronic stopping in solids, radiation detector physics, nanoscale defect/interface engineering, ion-beam modification and synthesis of materials, impurity diffusion in solids, environmental degradation of materials, numerical simulation, and applications of ion-beam analysis techniques. Her research has also included developing automatic instrumentation control programs for accelerator beam lines and end-stations, as well as the computational capabilities for multi-dimensional data acquisition and fast data analysis in association with high-resolution time-of-flight spectroscopy and ion-channeling. Dr. Zhang has experience with various ion sources, tandem accelerators, ion implanters, vacuum systems, channel plate, solid-state detectors, gas ionization detectors and electronics.

Awards and Recognitions
2008 Invited to participate in the 14th annual German-American Kavli Frontiers of Science (GAFOS) symposium in Potsdam, Germany on June 11-14, 2008. The symposium, co-sponsored by the Alexander Von Humboldt Foundation and the U.S. National Academy of Science (NAS), is the Academy’s premiere activity for distinguished young scientists. Attendees are selected by a committee of Academy members from among young researchers who have already made recognized contributions to science. Since its inception in 1989, more than one hundred of its “alumni” have been elected to the National Academy of Sciences, and eight have received Nobel Prizes.
2008 Invited to participate at the 2008 German-American Frontiers of Engineering (GAFOE) Symposium, in Irvine, CA, April 24 -27, 2008 that is hosted by the National Academy of Engineering (NAE) and the Alexander von Humboldt Foundation. The invitation-only GAFOE aims to bring together outstanding, early-career German and American engineers to facilitate an interdisciplinary transfer of knowledge and methodology that could eventually lead to collaborative networks of engineers from the two countries.
2006 Recipient of the 2005 Presidential Early Career Awards for Scientists and Engineers (PECASE). This is the highest honor bestowed by the United States government on outstanding scientists and engineers beginning their independent career.
2006 Recipient of the 2005 DOE Office of Science Early Career Scientist and Engineer Award with 5 years of research funding.
