Présentation

From Sep. 2014, I joined [Université de Lorraine](https://www.univ-lorraine.fr/) as an associate professor. More precisely, I do my teaching at Computer Science departement of the [Faculté des Sciences et Technology (FST) Nancy](http://fst.univ-lorraine.fr). Also, I am a member of [Adagio team](http://adagio.loria.fr/) of the laboratory [LORIA](http://www.loria.fr). Previously, I was a postdoctoral researcher at Image, Processing and Tomography Lab of [ CEA](https://hal.archives-ouvertes.fr/www.cea.fr/)-Saclay, France. I was working on a project about volumic accelerated reconstruction algorithm in X-ray tomography for early osteoarthrisis diagnostic, low dose and low cost. I received my PhD in Oct. 2013 from [ Université Paris-Est Marne-la-Vallée (UPEMLV)](http://www.univ-paris-est.fr/fr/), France. My thesis is entitled **Rigid transformations on 2D digital images: Combinatorial and topological analysis**, and was carried out in the A3SI team of the [ Laboratoire d'Informatique Gaspard Monge (LIGM) ](http://igm.univ-mlv.fr/LIGM) at [ESIEE-Paris](http://www.CIMS./) Engineering school, under the supervision of Prof. [ Yukiko Kenmochi](http://www.esiee.fr/~kenmochy/index-eng.html) and [ Hugues Talbot ](http://www.esiee.fr/~talboth/)and [Nicolas Passat](http://crestic.univ-reims.fr/membre/1542-nicolas-passat). My research topic is in the area of **Discrete Geometry and Topology**, applied for Computer Vision and Image Analysis. I focus in particular on rigid transformations (i.e., transformations composed of rotations and translations) and the combinatorial structure modelling the parameter space of such transformation on arbitrary finite subset of Z2. I am also interested in **Tomographic Imaging**, and my post doctoral project was on 3D reconstruction algorithms based on sparse reconstruction with TV regularization in X-ray tomography (CT). I am currently working on **Digital Curve Analysis**. More precisely, I study the geometrical characteristics of noisy digital contours using the discrete structures such as maximal segment, blurred segment, tangent cover. I am also working on subjects related to **Wood Image Analysis** such as pith detection, wood-log segmentation and wood detect detection.
