About me

Current status

Mohamed Nadjib Mami, A Research Associate at IAIS Fraunhofer and a PhD student at EIS Bonn University, Germany. My research topic is enabling  the access to original heterogeneous and large data sources, ake Data Lake, in a uniform manner using one query. Semantic Web technologies are used to achieve this aim, resulting in the so-called Semantic Data Lake.

My interests can be summarized as follows:

  • Heterogeneous Databases
  • (Big) Data Management
  • Semantic Web and Linked Data

Education

  • Master’s Degree “Intelligent Systems” – Paris Dauphine University, Paris, France.
  • Master’s Degree “Software Engineering” – Saad Dahlab University – Blida, Algeria.
  • Bachelor’s Degree “Computer Science” – Saad Dahlab University, Blida Algeria.

 Professional Experience

  • Researcher – Fraunhofer IAIS – Germany.
  • Intern “Object-Non-Relational Mapping, Meta-Modeling, NOSQL Databases esp. Graph” – KamricSoft – Paris, France.
  • Web Developer “E-commerce websites” – Kadik2i, Algeria/France.

 Honors and Awards

  • Best Mini-project in SSSW15 Summer School – 2015, Italy (team award).
  • Second Award of “Forum National des Etudiants en Informatique” (FNEI) – 2011, Algeria.
