Postdoctoral Fellow Position Available in the Lab of Dr. Melody Zeng

The Zeng lab is seeking motivated and enthusiastic postdoctoral fellows to join our lab to lead projects to investigate gut microbiome-host interactions in the contexts of early immune system development or cancer progression and metastasis. The Zeng has developed innovative gnotobiotic mouse models and genetic knockout mice for studies of the development of the immune system and the crosstalk between immune cells and gut bacteria in infection and cancer. We are well equipped to integrate multi-disciplinary approaches to study the interactions between immune cells and gut commensal bacteria using mouse models of inflammation, infection or cancer, and gnotobiotic mouse models established by leveraging an existing human stool biobank in the Zeng lab.
