Research Interest

Selective targeting and reprogramming of cells using fully degradable nanomedicines
In the laboratory of Nanomedicine we are studying how to manipulate cells functions in order to generate novel therapeutic strategies to treat inflammatory diseases and cancers. We operate in a two-arm approach. In the first, we design, fabricate, develop and characterize novel nanocarriers for selective systemic targeting to variety of cell types involved in inflammatory diseases and different types of cancers. In the second, we utilize our technologies for drug discovery, and personalized medicine approach. In both arms, we are combining multidisciplinary approaches including immunology, cell and molecular biology, genetics, protein engineering, material sciences, nanotechnology and computational techniques to develop innovative therapeutics to target specific cells within the immune system and special epithelial cells. Our ultimate goal is to translate some of our findings into clinical settings.

We are particularly interested in:

  1. Identifying key genes responsible for multipotent hematopoietic stem cells self-renewal properties.
  2. Studying the role of cell cycle regulators in proliferation, migration, and cytokine production in lymphocytes, macrophages and dendritic cells during inflammatory bowel diseases.
  3. Developing and studying novel approaches to target cancer stem cells.
  4. Harnessing siRNAs and miRNAs as novel tools for drug discovery and for therapeutic applications.
  5. Investigating novel approaches to treat blood cancers such as mantle cell lymphoma and acute myeloid leukemia.
  6. Manipulation of hair follicle stem cells to control hair growth, and skin cancers.
