My name is Zheng Zhong, and I am a scientist researching the 3D bioprinting of stem cells for regenerative medicine and disease modeling. I obtained my Ph.D. degree in Nanoengineering from the University of California, San Diego in Dr. Shaochen Chen’s lab, and I have published papers as the first author in Biomaterials and Biofabrication and co-authored publications in Nature, Nature Materials, Cell Research, and PNAS.
