Dr. Dinwiddie is a hydrogeologist who develops integrated geophysical and remote-sensing characterization methodologies to investigate hydrologic processes on Earth and Mars. Recently, her work has focused on understanding the phase state of water in subarctic aeolian and thermokarstic environments, characterizing environmental conditions---including subfreezing temperatures---under which alluvial debris flows develop on subarctic dune slipfaces, quantifying the evolution of subarctic thaw lake surface area, parameterizing landscape-scale models for assessing risk of subarctic slope instability under changing climate, developing soil moisture and soil freezing characteristic curves for Martian soil simulants and terrestrial sands, and documenting the characteristics of Fe-oxide concretions that form through preferential flow fingering after a fluvial sandstone reservoir transitions from fully to variably saturated. She has broad expertise in mechanical engineering, environmental science, and the mathematical sciences, and 14 years experience in organizing and conducting field investigations in remote environments. Natural and physical analog studies have been a consistent theme throughout her career. She conducts petrophysical investigations into the subsurface heterogeneity of terrestrial planetary bodies and works with field and laboratory instrumentation and geophysical techniques to quantify hydrologic property distributions. She has developed numerical and semianalytical models of hydraulic and pneumatic flow near measurement instruments, which led to understanding the effect of the instrument on the natural system, the size and shape of the measurement averaging volume, and guidelines for instrument use and data interpretation. She has analyzed primary and secondary heterogeneities within shoreface and fluvial sandstones, active sand dunes and sand sheets, organic- and ice-rich polygonal soils, volcanic ignimbrites and fluvially reworked volcaniclastics. Dr. Dinwiddie was honored in 2010 as a rising star by San Antonio Business Journal’s 40 under 40 listing, for which she was nominated for fostering involvement of Southwest Research Institute® in earth system science, including spearheading an internal research and development initiative to open a new arena of research in the development and use of earth observation systems to monitor, mitigate, and adapt to global environmental change. She has authored or coauthored 20 peer-reviewed articles, and received both the 2007 Rossiter W. Raymond Memorial Award and the 2007 Alfred Noble Prize for her article published in Reservoir Evaluation & Engineering. Dr. Dinwiddie has served as a panel reviewer for NASA and NSF, as a technical reviewer for NASA grant and technology development proposals, and as a peer reviewer for Earth Surface Processes and Landforms, Journal of Hydrology, Journal of Hydrologic Engineering, Transport in Porous Media, Ground Water, and Environmental Science & Technology. She currently has profile pages on Google Scholar, ResearchGate, and ResearcherID.
