Research Topics

Post-Doc research
My research focuses on Big data and machine learning in pharma and medicine. The main idea is to assess the risk of food allergy using machine learning and Big Data and help consumers make decisions.

PhD thesis
My main field of interest was the Text-Based Medical Image Retrieval.
The main idea is to propose a set of Medical-Dependent Features that are composed of medical terminologies and imaging modalities. Then to study their impact on two research axes: image retrieval and query classification.

Master's thesis
An approach for deploying and managing distributed applications with monitors.
The main idea is to propose an UML profile and an architect's guide in order to model the distributed applications with monitors, step by step, based on the UML profile

Reviewer of the following conferences :
- AICCSA 2017: 14th ACS/IEEE International Conference on Computer Systems and Applications.
- JIA 2018: Journée d'Informatique Appliquée.
