Research Experience and Interests

Dr. Sophie Voisin joined the Geographic Information Science and Technology (GIST) group at ORNL in April 2014 as a Postdoctoral Associate. She is currently involved in projects using satellite imagery.

Doing her PhD research, she was a research assistant with the Imaging, Robotics, and Intelligent Systems Laboratory at The University of Tennessee, after her graduation she was involved in program development activities. She first started at the Oak Ridge National Laboratory (ORNL) as Postdoctoral Research Associate at the Spallation Neutron Source. Her work included applied signal and image processing, 2D and 3D image understanding, and neutron imaging analysis for various industrial and academic applications related to quality control and process monitoring. Then, she was part of the ORNL Biomedical Science & Engineering Center. She worked on a project that combine image analysis and eye-tracking data and participate to the development of a clinical decision support system to help reduce medical errors.

Her current research interests focus on 2D and 3D image understanding and processing, machine learning, and high performance computing applied to satellite imagery.
