I graduated with a B.Sc. from the University of Science and Technology of Algiers in computer science (2010) and with an M.Sc. in image processing from the University of Paris Descartes (2011). I am currently pursuing a PhD under the supervision of Prof. C. Laporte in the Department of Electrical Engineering and Michael McGuffin in the Department of Software Engineering at École de Technologie Supérieure. My research aim is to develop a novel user-friendly interface for 3D freehand ultrasound (US) with visualization of uncertainty. The project includes 3D acquisition of US images from 2D standard probes, developing an interactive segmentation scheme that takes into account uncertainty measurement, 3D surface reconstruction from non-coplanar slices and, finally, modelling and visualizing uncertainty amounts and provenance.
