研究领域

Cell polarity is a fundamental feature of living cells and is essential for many cellular and developmental processes. My laboratory is interested in how cells establish their polarity and how this process is affected by aging. We focus on: 1) how cell polarization is driven by the cytoskeleton; 2) elucidating the roles of nuclear envelope proteins in regulating cell polarization; 3) identifying aging-associated secretory factors that affect cell polarity; 4) deciphering the molecular mechanism of polarity-related aging factors. Our goal is to provide better understanding of aging mechanisms and identify aging markers and targets for aging treatments.
