Chia-Wei Cheng, PhD
Dr. Chia-Wei Cheng, Ph.D.,joined the Columbia University faculty in 2021, where she is an Assistant Professor of Genetics and Development Biology and a Principle Investigator of Columbia Stem Cell Initiative (CSCI). Currently, Dr. Cheng is also a member of the Herbert Irving Comprehensive Cancer Center (HICCC). Dr. Cheng conducted her doctoral research in Dr. Valter D. Longo’s laboratory and received her Ph.D. in Biological Sciences from the University of Southern California (USC). Dr. Cheng completed her postdoctoral training in Dr. Omer H. Yilmaz’s laboratory at Koch Institute for Integrative Cancer Research, Massachusetts Institute of Technology (MIT), with the support of the Helen Hay Whitney Foundation (HHWF). Dr. Cheng’s fellow-to-faculty transition research is supported by the NIH Pathway to Independence Award (K99/R00), with Dr. David M. Sabatini's co-mentorship.

Adaptation to dietary changes profoundly influenced human evolution and continues to impact our modern lives in health and diseases. After embryonic development, tissue-resident adult stem and progenitor cells remain the capacity to adjust their regenerative activity in response to diets and nutritional states to maintain tissue homeostasis. Such adaptation must rely on the systemic mediators integrating the inter-organ crosstalk to coordinate whole-body metabolism and the intracellular signaling machinery converting the nutritional messages into the transcriptional regulatory actions to determine the stem cell fate.
Our research focuses on the interface of nutritional and transcriptional regulatory networks. We study how adult stem and progenitor cells perceive the nutritional states and fine-tune their lineage decisions in tissue regeneration and disease development processes. Our goal is to illustrate the conversion from the nutritional perception to cell fate decisions at the single-cell level, in the hope of inspiring new therapeutic strategies. Towards this end, we use genetic mouse models, organoid systems, and transplantation experiments to identify and characterize the endocrinal and metabolic cell-fate determinants in the contexts of tissue homeostasis and adaptation to diet. Current projects investigate the therapeutic potential of signaling metabolites in treating cancer, diabetes, and age-related degenerative diseases.
