We are hiring! We are seeking motivated Ph.D. students (fully funded) starting in Spring/Fall 2024, and postdoctoral fellows to conduct research at the nexus of microfluidics, stem cell biology and bioinformatics. Please send your inquiry to Dr. Yi Zheng with a detailed CV (yzheng88@syr.edu).

Biomedical researches using established cell lines and animal model systems have achieved tremendous success in improving our understanding of fundamental biological mechanisms and facilitating the discovery of new medicines. Nevertheless, there is growing realization that information obtained from simple dish-cultured cell lines and other animals can not be directly extrapolated to human systems. Human pluripotent stem cells (hPSCs), under proper culture conditions, can self-organize into structures that resemble the in vivo anatomy and physiology of certain human tissues, which can potentially revolutionize current biomedical researches by providing a more human-relevant setting. In the Zheng Lab, we build highly controllable and reproducible human biosystems using stem cells and a wide array of engineering approaches, including micro/nanoengineering, single-cell technologies, bioinformatics and synthetic biology, and apply these biosystems for new discoveries in human development, disease etiology and regenerative medicine (Media highlights: Nature News 2019Nature News Feature 2021MIT Technology Review 2019, NPR, BBC).
