Welcome Dr Anna Harrison and Dr Elisabeth Steel


The Department of Geological Sciences and Geological Engineering would like to welcome its two newest faculty members, Dr Anna Harrison, and Dr Elisabeth Steel.

Dr Anna Harrison joined the department in September 2018. Dr Harrison is a Queen’s national scholar and is cross-appointed between Geological Sciences and Geological Engineering and the School of Environmental Studies. Her research interests are within aqueous and environmental geochemistry, and include experimental, analytical, and reactive transport modelling approaches, complemented by field data. This research not only helps to address the fundamental geochemical questions of what controls mineral dissolution-precipitation reactions, but has important implications for understanding natural mineral weathering and element cycling processes over geologic time, and for issues of immediate environmental significance such as groundwater contamination, nutrient availability, and engineered CO2 sequestration under a changing environment. Specific research projects include investigating natural CO2-mineral weathering feedbacks over geologic time, engineered CO2 sequestration, contaminant uptake and release in sulphate, carbonate, and Fe-bearing minerals, and elucidating the role of water in mineral weathering reactions.

Dr Elisabeth Steel will start with the department January 1, 2019. Dr. Steel will be studying clastic sedimentary systems via a combination of field work and physical modeling. She will be building an experimental facility in the Coastal Engineering Lab designed for modeling deltas and turbidity currents in order to examine the various ways that the dynamics of these systems are recorded by the morphology and architecture of their deposits. She will also be developing field projects with the goal of comparing experimental results to ancient and modern systems. Ongoing work includes: quantifying the kinematics of channel networks on delta surfaces; developing methods for predicting deltaic stratigraphy based on surface kinematics; characterizing lateral spreading rates of turbidity currents; and predicting lift-off distances of lofting turbidity currents.

Both Dr Harrison and Dr Steel are actively encouraging interested students to apply to join their research groups as graduate students. Anyone interested is welcome to contact them directly.

 

Please join us in welcoming both Dr. Harrison and Dr. Steel to the department!
