Hao F. Zhang is a Professor of Biomedical Engineering at Northwestern University. He received his Bachelor and Master degrees from Shanghai Jiao Tong University (Shanghai, China) in 1997 and 2000, respectively, and his Ph.D. degree from Texas A&M University (College Station, Texas) in 2006. From 2006 to 2007, he was a post-doctoral fellow at Washington University in St. Louis. He and colleagues reported the first demonstration of photoacoustic microscopy (Nature Biotechnology 2006, Nature Protocols 2007, PNAS 2010), the first spectroscopic super-resolution imaging (Nature Communications 2016), and the first observation of intrinsic stochastic fluorescence emission from DNA (PNAS 2016). He received the NSF CAREER award and NIH Director’s Challenge Award in 2010, the NIH IMPACT award in 2015, the SPIE Translational Research Award in 2016, and the US National Academy of Sciences Cozzarelli Prize in 2017. His research interests include optical coherence tomography, super-resolution imaging, single molecule imaging, vision science, and cancers. He is an associate editor of Biomedical Optics Express and is a chartered member of the NIH Neuroscience and Ophthalmic Imaging Technologies (NOIT) study section. In 2015, he co-founded Opticent Health to commercialize optical coherence tomography technologies developed in his lab.
