Présentation

Since september 2015, Dr. Mohamed Morchid is [**Associate Professor**](https://fr.wikipedia.org/wiki/Maître_de_conférences_(France)) in the Laboratoire Informatique d'Avignon (LIA) within the [University of Avignon](http://univ-avignon.fr), France and Ass. Prof. Mohamed Morchid has obtained the [**Habilitation à Diriger des Recherches (HDR) in computer sicence**](https://fr.wikipedia.org/wiki/Habilitation_universitaire#En_France) at november 26th 2019. He also gives different courses on computer science at the Centre d'Enseignement et de Recherche en Informatique (CERI) of the University of Avignon. The research interests of Dr. Mohamed Morchid lie on [**Artificial Intelligence (AI)**](https://en.wikipedia.org/wiki/Artificial_intelligence) with a special focus on deep neural networks with applications on [**Natural Language Processing (NLP)**](https://en.wikipedia.org/wiki/Natural_language_processing). From septembre 2014 to august 2015, Dr. Morchid has been an Teaching and Research Assistant within the [University of Avignon](http://univ-avignon.fr), France. He has pursued his research by proposing a robust representation of noisy documents from an automatic speech recognition system in a reduced space. Then, Ass. Prof. Morchid has proposed original methods based on topic models to locate short text messages from sharing platforms. From november 1st 2013 to febuary 1st 2014, Dr. Mohamed Morchid spents time visiting the [Microsoft Research](http://research.microsoft.com/en-us/labs/cambridge/) (Cambridge, UK) Laboratory and worked on the [PowerPoint Assistant](http://research.microsoft.com/apps/video/default.aspx?id=211308) international project. He has proposed original methods to allow Microsoft customers to enrich their PowerPoint presentations with relevant content. Mohamed Morchid has obtained at 25th november 2014 his Ph.D. in Computer Science within the LIA on Natural Language Processing (NLP), and more precisely, he has proposed robust representation of noisy documents from an automatic speech recognition system (dialogues) or from sharing platforms such as Twitter or Youtube. In addition, Dr. Mohamed Morchid serves as Associate Editor for [ IEEE/ACM Transactions on Audio, Speech and Language Processing](https://signalprocessingsociety.org/publications-resources/ieeeacm-transactions-audio-speech-and-language-processing/editorial-board) and as Action Editor for [ACL Rolling Review](https://www.aclweb.org/adminwiki/index.php?title=ACL_Rolling_Review_Proposal).

Depuis septembre 2015, Dr. Mohamed Morchid est [ **Maître de Conférences**](https://fr.wikipedia.org/wiki/Maître_de_conférences_(France)) au sein de l'[Avignon Université](http://univ-avignon.fr) et il a soutenu son [**Habilitation à Diriger des Recherches (HDR) en Informatique**](https://fr.wikipedia.org/wiki/Habilitation_universitaire#En_France) le 26 novembre 2019. Ses travaux de recherche sont réalisés au Laboratoire Informatique d'Avignon (LIA) et son service statutaire est effectué au Centre d'Enseignement et de Recherche en Informatique (CERI) de l'Univeristé d'Avignon. Les thèmes de recherche de Dr. Mohamed Morchid s'articulent autour de l'[**Intelligence Artificielle (IA)**](https://fr.wikipedia.org/wiki/Intelligence_artificielle), et plus particulièrement, des réseaux de neurones profonds pour le [ **Traitement Automatique du Langage (TAL)**](https://fr.wikipedia.org/wiki/Traitement_automatique_du_langage_naturel). De septembre 2014 à août 2015, Mohamed Morchid a été Attaché Temporaire d'Enseignement et de Recherche (ATER) à l'[Université d'Avignon](http://univ-avignon.fr). Il a poursuivi, dans un premier temps, ses travaux pour une représentation robuste de documents parlés fortement bruités ainsi que pour la localisation automatique de documents issus du Web. Du 1er novembre 2013 au 1er fevrier 2014, Ass. Prof. Morchid a effectué un séjour de recherche au sein du laboratoire [Microsoft Research](http://research.microsoft.com/en-us/labs/cambridge/) sur le projet international de l'[Assistant PowerPoint](http://research.microsoft.com/apps/video/default.aspx?id=211308). Dans ce contexte, Dr. Mohamed Morchid a proposé des méthodes originales de traitement automatique du langage permettant aux utilisateurs d'enrichir leurs présentations PowerPoint avec du contenu informatif. Ass. Prof. Mohamed Morchid a obtenu le 25 novembre 2014 le doctorat en Informatique au sein du Laboratoire Informatique d'Avignon dans le domaine du traitement automatique du langage, et plus précisement, sur la représentation robuste de documents fortement bruités issus de transcriptions automatiques de douments parlés (dialogues) ou issus de plates-formes d'échange comme Twitter ou Youtube. De plus, Ass. Prof. Morchid est editeur associé pour le journal [IEEE/ACM Transactions on Audio, Speech and Language Processing](https://signalprocessingsociety.org/publications-resources/ieeeacm-transactions-audio-speech-and-language-processing/editorial-board) et "Action editor" pour [ACL Rolling Review](https://www.aclweb.org/adminwiki/index.php?title=ACL_Rolling_Review_Proposal).
