Biography
Dr. Sun received his bachelor degree from Jilin University in 2004, and obtained his Ph.D. degree in single molecule biophysics from Institute of Physics, Chinese Academy of Science in 2009. After graduation, he joined Cornell University and Howard Hughes Medical Institute and did his postdoc research from 2009 to 2015. Dr. Sun joined School of Life Science and Technology of ShanghaiTech University as an assistant professor, PI since September 2015.

Research Interests
Many biology reactions are too complex to fully comprehend through the use of conventional ensemble techniques. Studying one biological macromolecule at a time, or biology in singulo, can provide us with extraordinarily clear and often surprising views of these molecules in action. In the last 20 years, single molecule techniques, including magnetic tweezers and optical tweezers, have enabled significant advancement in the understanding of a wide variety of biomolecular systems, especially those involving DNA and associated proteins. My research interests are focused on understanding the mechanisms of molecular motors in the process of DNA replication, repair and transcription by using single‐molecule techniques and developing technological innovations to meet the challenges in the pursuits.
