RESEARCH INTERESTS

Dr. Chang has an interest in studying how external cues (e.g. diet, temperature, and exercise) regulate gene expression in a tissue-specific manner and how this regulatory network is altered in obesity and diabetes. Her research is currently focusing on the role of NT-PGC-1a, a short isoform of PGC-1a transcriptional coactivator, in the regulation of brown fat transcription programs in response to environmental and nutritional stimuli.
