Prof. TIAN Xiaoyu (田小雨) is an Assistant Professor of the School of Biomedical Sciences, The Chinese University of Hong Kong (CUHK).  She received PhD from CUHK Department of Physiology.  She studied the therapeutic effect of PPARs on vascular dysfunction in hypertension and type 2 diabetes, and mitochondrial oxidative stress in endothelial cell function.  After graduation, she continued as a postdoctoral fellow in the Cardiovascular Research Institute, the University of California San Francisco, studying macrophage dynamics in obesity-induced adipose tissue inflammation, and also in the atherosclerosis.  She later joined CUHK again as Research Assistant Professor in 2015, and is Assistant Professor since 2017.  Her current research interests include the regulation of macrophage function by molecular clock components in the vascular microenvironment of cardiovascular diseases.  She also works on adipose tissue inflammation and immune regulation of obesity and insulin resistance.

  1. Function of molecular clock in cardiovascular diseases.
  2. Macrophage function in metabolic syndrome.
