Biography

Dr. Diana Azzam earned her PhD in Biochemistry & Molecular Biology from the University of Miami in 2012. Her research has focused on the identification, isolation and functional characterization of chemo-resistant and metastatic cancer stem cell subsets in the most lethal forms of breast and ovarian cancers. Based on her work and publications, she was a recipient of the 2014 Women in Cancer Research scholar award from the American Association for Cancer Research.  Dr. Azzam completed her postdoctoral training in drug discovery and epigenetics, where she optimized a high-throughput screening approach to identify novel drugs that target therapy-resistant cancer stem cells subsets in a tumor. Her research efforts led to the identification of new cancer stem cell-specific functions of histone methyltransferases (HMT) and histone deacetylases (HDAC) in breast and ovarian cancers.

Dr. Azzam also established a patient-specific ex vivo drug screening platform for personalized cancer therapy. Her approach tests clinically approved drugs on chemo-resistant patient cells and identifies the most effective drugs to be readily re-purposed in the clinic for immediate use. This novel, iterative functional/genomics approach to personalized therapeutics was a multidisciplinary collaborative project with oncologists and validation of this assay was done on leukemias, breast, ovarian, esophageal and sarcoma tumors.

Dr. Azzam joined the Department of Human and Molecular Genetics at the Florida International University in August of 2016. She is currently working on the genetics and therapeutic targeting of cancer stem cells in breast and ovarian cancers. She is committed to identifying novel therapeutic approaches for the advancement of treatment and improving survival rates of cancer patients.
