Le Thi Hoai An
 earned her PhD with Highest Distinction in Optimization in 1994, and her Habilitation in 1997 both from university of Rouen, France. From 1998 to 2003 she was Associate Professor at the National Institute for Applied Sciences, Rouen. Since 2003 she is Full Professor at the University of Paul Verlaine – Metz (which becomes University of Lorraine in 2012). She is currently Director of Laboratory of Theoretical & Applied Computer Science, university of Lorraine and serving as Exceptional Class Professor. She is the author/co-author of more than 200 journal articles, international conference papers and book chapters, the co-editor of 5 books and 10 special issues of international journals, and supervisor of 26 PhD theses. She is Chair of Scientific Committee and Chair of Organizing Committee as well as member of Scientific Committee of numerous International Conferences, and leader of several regional/national/international projects. Her research interests include Numerical Analysis, Optimization and Operations Research and their applications in Information Systems and Industrial Complex Systems in various fields such as, Data Mining and Machine Learning, Telecommunication, Transportation, Supply Chain and Management, Finance, Bioinformatics, Image Analysis, Cryptology, Security & Reliability. She is the co-founder (with Pham Dinh Tao) of DC programming and DCA, an innovative approach in nonconvex programming and global optimization. These theoretical and algorithmic tools, becoming now classic and increasingly popular, have been successfully applied by researchers and practitioners all the world over to model and solve their real-world smooth/nonsmooth nonconvex programs, especially in the large-scale setting.
