Dr. Meital Charni-Natan | Pharmacology | Best Researcher Award

IIBR | Israel

Dr. Meital Charni-Natan is an accomplished molecular biologist whose research focuses on the transcriptional and metabolic regulation of liver function under nutritional and hormonal cues. She earned her B.Sc. in Life Sciences from Ben-Gurion University of the Negev with high honors, followed by an M.Sc. and Ph.D. in Life Sciences from the Weizmann Institute of Science, where she investigated the roles of p53 signaling and its non-cell-autonomous functions in liver metabolism under the supervision of Prof. Varda Rotter. She later completed a postdoctoral fellowship at The Hebrew University of Jerusalem under Dr. Ido Goldstein, exploring transcriptional responses to fasting, refeeding, and metabolic adaptation in hepatocytes. Dr. Charni-Natan currently serves as a Researcher at the Israel Institute for Biological Research, Department of Pharmacology, where her work integrates genomic, epigenetic, and metabolic profiling to uncover regulatory mechanisms governing hepatic physiology and disease. Her contributions have been recognized with several awards, including the Golda Meir Excellence Fellowship and the First Place Poster Award at the 19th Medical Chemical Defense Conference (2025). Through her pioneering research, Dr. Charni-Natan continues to advance understanding of metabolic gene regulation and its implications for liver health and systemic homeostasis.
