overview

Dr. Liang is dedicated to advancing women's health through translational research. Equipped with state-of-the-art technologies in biomedical science, her laboratory is well-prepared for comprehensive analyses at various levels, from tissues to cells and molecules. This allows her and her team to explore intricate biological processes and gain deeper insights into various health conditions affecting women. Her funded projects aim to 1) understand the impact of diabetes on the vaginal tissue and the host response to urogynecologic meshes; 2) define the role of hyperglycemic memory in innate immune response to medical implants; and 3) determine the effect of perioperative glycemic control on long-term surgical outcomes.
