Dr. Nissim joined Abintus in 2022 and serves as Head of Synthetic Biology.  Dr. Nissim concurrently serves as an Assistant Professor and Head of Biomedical Synthetic Biology group at the Hebrew University of Jerusalem. Dr. Nissim is an internationally recognized pioneer in the field of synthetic biology and has developed several novel biological engineering platforms for biomedical applications, combining multidisciplinary training in biology, biophysics, and synthetic biology. As part of his Ph.D. work, Dr. Nissim pioneered the very first engineered gene circuit for precise targeting of cancer cells. In his postdoc training, his team developed advanced synthetic RNA-based gene circuits for cancer immunotherapy, a high-throughput screening approach for identifying Synthetic Promoters with Enhanced Cell-State Specificity (SPECS), an integrated RNA and CRISPR/Cas gene regulation toolkit, and Synthetic Circuit-Driven Expression of Heterologous Enzymes for Disease Detection. Currently, his group is focused on developing advanced technologies that enable cell-state specific gene expression. These technologies are enabling the advancement of next-generation cancer therapies, antiviral vaccines, and other biotechnology innovations. He completed his postdoctoral research at the Massachusetts Institute of Technology and at the Weizmann Institute of Science, where he also received his Ph.D. in synthetic biology. Prior to that, he accomplished his M.Sc. at the Weizmann Institute of Science, where he performed basic cancer research.
