The biology of cancer is the main field of research that fascinated Dr. Saad Sabbar Dahham. He is interested in targeting tumors by inhibiting angiogenesis and understanding other mechanisms that are at play which can influence angiogenesis. Currently his team is developing metastatic xenograft tumor models that can mimic the multistep process of metastasis to various target organs. With such model, he hopes to be able to discover new compounds that may be therapeutically useful during this stage of carcinogenesis. In the last few years, he started his research on natural product and their roles against cancer cells. With the wide experience in the biological sciences, he published many articles in Scopus and ISI journals and presented abstracts in many worldwide conferences. A part of angiogenesis interest, he recently won the gold award in the International Conference and Exposition on Inventions by Institutions of Higher Learning (PECIPTA 2015) for invented Mu-DermTM (A natural angiogenic product for wound healing).
