Hao Wu (Chinese: 吴皓; pinyin: Wú Hào) is a Chinese American biochemist and crystallographer and the Asa and Patricia Springer Professor of Structural Biology in the Department of Biological Chemistry and Molecular Pharmacology at Harvard Medical School. Her work focuses on molecular mechanisms of signal transduction in cell death and inflammation. She is the discoverer of signalosomes, which are large macromolecular complexes involved in cell death and in innate and adaptive immune pathways. She has established a new paradigm for signal transduction that involves higher-order protein assemblies. She has received the Pew Scholar Award, the Rita Allen Scholar Award, the Margaret Dayhoff Memorial Award, the NYC Mayor's Award for Excellence in Science and Technology, NIH MERIT and Pioneer Award
