Since 2013, my research activities have focused on medicinal chemistry. My activity is centered on the development of new therapeutic molecules. Pathologies of interest are parasitic diseases such as malaria (Plasmodiums), trypanosmiases (Chagas disease, sleeping sickness ... due to Trypanosomas) and leishmaniases (visceral and cutaneous due to Leishmanias). Thus, the synthesis of new derivatives for the treatment of these diseases are carried out. In addition, I’m also conducting research to elucidate the mechanisms of action of the new synthesized molecules, either in the laboratory or in collaboration. The new derivatives are also tested on different parasites by collaboration with BIOCIS for their antiparasitic activities (3 publications).

Since September 2015, I am also involved in a European project (JPIAMR) for the synthesis of carbapenemase inhibitors (NDM-1) directed against antibiotic-resistant bacterial strains (Gram-negative bacteria) (1 patent in preparation).

Finally, since January 2016, a new project has been set up on the development of anti-cancer agents by pharmacomodulation of natural molecules (Gambogic acid, Tagitinin C) in partnership with Pr G. Vo-Thanh (ICMMO, ECM). Two teams of biologists are involved in the project: one team in Vietnam and another in Korea (1 publication in preparation).
