Dr. Qian is an Instructor of Medicine at Harvard Medical School, an Associate Physiologist at Brigham and Women’s Hospital (BWH), and the Associate Director of the Medical Chronobiology Program at BWH. She has been actively involved in the research of the circadian system and physiology for over 10 years. Dr.Qian joined the Medical Chronobiology Program at Brigham and Women’s Hospital and Harvard Medical School in 2015. Since then, she 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. Her research is primarily focused on the physiological mechanisms by which timing of behavior, such as food intake and physical activity, can interact with the circadian system, and synergistically affect cardiometabolic outcomes. She is also interested in understanding the interindividual differences based on sex and genetics in these interactions. For example, She has demonstrated the impacts 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 physical activity on cardiometabolic health. At every stage of her training she has been awarded fellowships or training grants that recognize academic excellence, research ability, and leadership, including a postdoctoral fellowship from American Diabetes Association, a pilot and feasibility grant from Nutrition Obesity Research Center at Harvard, and a prestigious K99 Award from NIH.

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.
