Sophie Voisin Contact Geographic Information Science & Technology Office: (865) 574-8235 Information Oak Ridge National Laboratory E-mail: [email protected] Oak Ridge, TN 37831-6017 Citizenship: France US Permanent Resident Biosketch Dr. Sophie Voisin received her PhD Degree in Computer Science and Image Processing from the University of Burgundy, France, in 2008. She was a visiting scholar with the Imaging, Robotics, and Intelligent Systems Laboratory at The University of Tennessee from October 2004 to December 2008 to work on her PhD research, and subsequently was involved in program development activities. In September 2010, she joined the Oak Ridge National Laboratory (ORNL) as a Postoctoral Reseach Associate to support various efforts related to applied signal processing, 2D and 3D image understanding, and high performance computing. Firstly, she worked at the ORNL Spallation Neutron Source performing quantitative analysis of neutron image data for various industrial and academic applications related to quality control, process monitoring, and to retrieve the structure of objects. Then, she joined the ORNL Biomedical Science & Engineering Center to develop on one hand image processing algorithms for eyegaze data analysis and on the other hand text processing techniques for social media data mining to correlate individuals' health history and their geographical exposure. Noteworthily she was part of the team that received a R&D 100 award for the developement of a personalized computer aid diagnostic system relying on eyegaze analysis for decision making. Since April 2014, she has been working for the Geographic Information Science & Technology group. Her research focuses on developing multispectral image processing algorithms for CPU and GPU platforms for high performance computing of satellite imagery.
