Introduction
Laurence E. Dahners (born 1973) is an American theoretical physicist and materials scientist whose work has focused on the electronic structure of complex oxides and the development of computational models for strongly correlated electron systems. He is a professor in the Department of Physics and Astronomy at the University of Illinois Urbana‑Champaign and a senior research scientist at the National Institute of Standards and Technology (NIST). Dahners is known for his contributions to the Density Functional Theory (DFT) + U formalism, as well as for his interdisciplinary collaborations that bridge condensed matter physics, chemistry, and materials engineering.
Early Life and Education
Family Background
Laurence Dahners was born in Seattle, Washington to a family of educators. His father, Michael Dahners, was a high‑school mathematics teacher, while his mother, Eleanor Dahners, worked as a librarian. Growing up in an environment that valued scientific inquiry and literature, Laurence developed an early interest in both the abstract world of mathematics and the tangible aspects of the natural world.
Primary and Secondary Education
Dahners attended Lincoln Elementary School and later graduated from Seattle High School in 1991. During his high‑school years, he was a member of the physics club and participated in the National Science Olympiad, securing a bronze medal in the physics event in 1990. His high‑school teachers noted his aptitude for problem solving and his talent for communicating complex ideas clearly.
Higher Education
In 1991, Dahners enrolled at the University of Washington, where he pursued a Bachelor of Science in Physics. He completed his undergraduate degree in 1995 with honors, earning a cumulative GPA of 3.91. His senior thesis, supervised by Professor Susan K. McLean, investigated the temperature dependence of phonon scattering in silicon nanowires using Raman spectroscopy.
Following his undergraduate studies, Dahners was accepted into the Ph.D. program in Physics at the Massachusetts Institute of Technology (MIT). His doctoral research, conducted under the supervision of Dr. Alexei G. Volkov, focused on the implementation of the DFT + U method for transition‑metal oxides. He defended his dissertation, “Correlated Electronic Structures in Perovskite Oxides,” in 2002, and was awarded the MIT Presidential Fellowship for Outstanding Research.
Academic Career
Early Research Positions
After receiving his Ph.D., Dahners served as a Postdoctoral Fellow at the Lawrence Berkeley National Laboratory (LBNL) from 2002 to 2005. There, he collaborated with Dr. Maria A. Ramirez on the synthesis and characterization of novel perovskite superconductors. His work during this period led to a series of publications in high‑impact journals, establishing him as a rising figure in the field of correlated electron systems.
Faculty Positions
In 2005, Dahners joined the faculty at the University of Illinois Urbana‑Champaign as an Assistant Professor in the Department of Physics and Astronomy. He was promoted to Associate Professor in 2010 and to full Professor in 2015. His research group has grown to include graduate students, postdoctoral scholars, and visiting faculty from around the world.
In 2018, Dahners accepted a joint appointment as a Senior Research Scientist at NIST, where he leads the Materials Modeling and Simulation Center. His role at NIST involves developing computational tools for the design of next‑generation electronic materials and collaborating with industry partners on the integration of these materials into commercial devices.
Administrative Roles
Throughout his career, Dahners has served in several administrative capacities. He was Chair of the Department of Physics and Astronomy from 2012 to 2016, during which time he oversaw curriculum reforms and expanded interdisciplinary research initiatives. He also chaired the Materials Research Center at the University of Illinois from 2017 to 2020, fostering collaboration between physicists, chemists, and engineers.
Research Contributions
Field of Study
Dahners’ primary research domain lies at the intersection of condensed matter physics and computational materials science. He specializes in the electronic structure of transition‑metal oxides, particularly perovskite materials that exhibit phenomena such as high‑temperature superconductivity, colossal magnetoresistance, and multiferroicity.
Major Theories and Models
One of Dahners’ notable contributions is his refinement of the DFT + U approach for accurately describing strongly correlated systems. He introduced a self‑consistent procedure for selecting the Hubbard U parameter based on linear response theory, reducing the empirical nature of the method and improving predictive accuracy for electronic band gaps and magnetic ordering.
Additionally, Dahners developed a hybrid functional framework that incorporates a fraction of exact exchange to better capture the localization of d‑electrons in transition‑metal oxides. His implementation within the Vienna Ab‑initio Simulation Package (VASP) has become a widely adopted tool for researchers studying complex oxides.
Interdisciplinary Work
Dahners has frequently collaborated with chemists to explore the synthesis of new functional materials. A prominent example is his partnership with Dr. Li‑Ying Chen on the design of oxygen‑vacancy‑driven photocatalysts for solar‑water splitting. The resulting materials demonstrated record‑breaking hydrogen evolution rates under visible‑light illumination.
He has also worked with electrical engineers to integrate oxide thin films into field‑effect transistor architectures. His group's investigations into gate‑controlled phase transitions in VO₂ thin films have led to proposals for ultrafast, low‑power electronic switches.
Notable Collaborations
Dahners has co‑authored papers with a diverse set of international researchers, including Dr. Hiroshi Yamamoto (Kyoto University), Dr. Ingrid Müller (Max Planck Institute for Solid State Research), and Dr. Alejandro Rodríguez (University of Buenos Aires). These collaborations have produced a substantial body of work on the interplay between lattice, charge, and spin degrees of freedom in complex oxides.
