Líney Árnadóttir received her B.S. in Chemistry from the University of Iceland 2001 and M.S. and Ph.D. in Chemical Engineering from the University of Washington 2007. Her thesis work included experimental electrochemistry for elevated temperature methanol oxidation in a micro-reactor combined with Density Functional Theory calculations of the same system under the guidance of Prof. Eric M. Stuve and Prof. Hannes Jónsson.

Before joining the faculty at OSU she worked as a Post. Doc. at NESAC/Bio using various surface analysis tools to determine protein orientation on self-assembly monolayers for biomaterials.

The Árnadóttir research group primarily uses computational methods to study chemical processes on surfaces with applications in renewable energy and material degradation. Kinetic modeling and density functional theory are the main computational approaches used to gain atomistic insights into these processes. The group frequently collaborates with experimental groups and uses experimental surface science tools to complement their computational methods.

Líney Árnadóttir is also a Scientist in the Physical Sciences Division of the Physical and Computational Sciences Directorate at Pacific Northwest National Laboratory (PNNL) and is the theory lead for the institute for Integrated Catalysis at PNNL.
