Research Interests

K. Bemis’s research interests are primarily cross-disciplinary combining the development of new computer-based algorithms to view and understand geologic phenomena with the study of the phenomena. In particular, she seeks to quantify and illustrate changing geologic phenomena using computer visualization techniques, especially feature segmentation methods. Specific projects include the fluid dynamics of seafloor hydrothermal plumes, the growth of cinder (scoria) cone volcanoes, and the evolution of faults in 2D and 3D. Her research focuses on clarifying the controls on fluid flow and transport in geologic processes using both analytical and numerical methods. Results have been presented on particle sedimentation in seafloor hydrothermal plumes, the interaction of multiple plumes in a cross-flowing environment, and the connection between magma supply and volcanic growth. An interest in developing better visiospatial training techniques for the visualization skills needed in the geological sciences has grown out of the involvement of graduate and undergraduate students in her research. Important areas of focus include the capture if visualization properties that affect visualization comprehension and the creation of cognitive strategies to overcome these difficulties.
