I have been actively involved in the research of circadian system and physiology since my PhD training at University of California, Los Angeles. My PhD thesis focused on the physiological and molecular mechanisms underlying the association between circadian disruption and poor glycemic control, with particular focus on regulation of pancreatic beta-cell function and survival in rodent model.This line of my research was among the first to identify the potential mechanisms by which environment/behavior-induced circadian disruption-common to modern life-can predispose to islet failure in type 2 diabetes. For my postdoctoral training, I joined the Medical Chronobiology Program at Brigham and Women’s Hospital and Harvard Medical School to continue my interests in circadian rhythm and physiology by transitioning into human studies, which allows me to address research questions that can be directly translated to human health. I led a highly controlled human in-laboratory study to investigate the effects of melatonin on glucose control and cardiovascular function, and their interactions with MTNR1B genotype. I am also interested in the impact of circadian misalignment on glycemic and appetite control, sex differences in energy metabolism under night shift, and the interaction effects of the circadian system and exercise on cardiometabolic health.

PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
