Gregg L. Semenza Johns Hopkins University School of Medicine, USA
Gregg L. Semenza is an American physician-scientist renowned for his groundbreaking research in oxygen sensing and cellular adaptation to hypoxia. He is best known for discovering hypoxia-inducible factor (HIF), a protein that plays a critical role in how cells respond to low oxygen levels. His work has significantly advanced understanding of cardiovascular disease, cancer, and anemia. Semenza’s discoveries have led to new therapeutic approaches targeting oxygen-related pathways. He received the Nobel Prize in Physiology or Medicine in 2019 for his contributions to oxygen sensing mechanisms. He has authored hundreds of scientific publications and is one of the most cited researchers in biomedical science. His research continues to influence modern cardiology and vascular biology. He is widely invited as a keynote speaker at major global conferences.
