Zhongbo lab is dedicated to elucidating the molecular mechanisms of human aging and cancer development. Our core research investigates single-molecule behaviors within individual cells, focusing on protein-nucleic acid interactions and protein-protein dynamics to identify potential therapeutic targets. We employ cutting-edge biophysical techniques including magnetic tweezers, optical tweezers, and atomic force microscopy (AFM). Beyond our work in telomere biology and epigenetic regulation, we pioneer instrument development through innovative bioconjugate chemistry and macromolecular engineering. Our current research portfolio encompasses telomere dynamics, DNA methyltransferases (DNMTs), RNA biology, and novel single-molecule detection platforms. The scientific illustration featured here was created by Ning Liu, demonstrating our commitment to integrating art and science.
