Dr. Rutherford is an assistant professor in geotechnical engineering, a licensed professional engineer in the State of Texas and teaches courses related to advanced soil testing, foundations and introduction to geotechnical engineering. Prior to coming to ISU, she worked for six years at TDI-Brooks International and was an assistant professor at the University of Illinois Urbana-Champaign. She recently recieved the NSF award “CAREER: Experimental Modeling of Tidal Current Turbine Foundations: An Integrated Research and Education Plan.” Dr. Rutherford is comitted to outreach to K-12 students and the general public. She has developed programs for the 2nd and 4th grades at Booker T. Washington STEM Academy, a tidal current curriculum for the Girls Adventures in Mathematics, Engineering, and Science (G.A.M.E.S) summer camp program and other programs for high school students and the general public. Dr. Rutherford also serves on a number of professional technical committees including the Soil Properties and Modeling Technical Committee of the Geo-Institute, the Marine Renewable Energy Technical Committee of the American Society of Civil Engineers, the D18 Soil and Rock Technical Committee of the American Society of Testing and Materials, the Marine Foundations Technical Committee of the Deep Foundations Institute and the Offshore Geotechnics Technical Committee of the International Society of Soil Mechanics and Geotechnical Engineering.

Dr. Rutherford's research interests are hazard mitigation, the characterization of soil subjected to dynamic loading and the design of offshore foundations for renewable energy applications. Her research team also works on the advancement of laboratory testing devices, centrifuge modeling, offshore in situ testing and investigation of offshore geohazards. Dr. Rutherford's research contributes to the development of offshore foundations, such as wind turbine foundations, tidal current turbines and subsea structures for energy production. She was recently awarded the National Science Foundation CAREER Award (CMMI-1454413) “Experimental Modeling of Tidal Current Turbine Foundations: An Integrated Research and Education Plan.” The research objective of this work is to evaluate suction caisson foundation systems for tidal current turbines by examining the foundation performance using both 1g bench-scale (conducted in transparent soil and Kaolin) and centrifuge testing under horizontal and vertical cyclic loading. The research focuses on the cyclic nature of the vertical, horizontal and moment loading due to waves, the rotation of the tidal current turbine blades and the change in direction of the horizontal loading due to ebb and flow tides. Decreasing the cost of the foundation system can be an important part of making tidal power a viable source of energy; however, it will require a better understanding of the soil-foundation system response to the possible loading combinations and tools to model the influence of the soil and foundation on the whole system. Her research also involves hazard mitigation and the characterization of soils under dynamic loading. A current project funded by the Nuclear Regulatory Commission (NRC-HQ-12-C-04-0117) investigates the stress-shear strain-volumetric strain behavior of dense sands under seismic loading. The collaborative research involves centrifuge testing (Prof. Scott Olson, University of Illinois), numerical modeling (Prof. Youssef Hashash, University of Illinois) and advanced laboratory testing (Dr. Rutherford). The experimental plan involves the use of a newly constructed multi-directional simple shear device based on work from her doctoral research at Texas A&M University (Rutherford 2012; Rutherford and Biscontin, 2008, 2009, 2010, 2013).
