Wang Ling
Assistant Professor


Ling Wang obtained her Ph.D. degree from Fudan University where she got training on biochemistry, molecular and structural biology in 2015. Then she pursued her postdoctoral training in single-molecule biophysics at The Rockefeller University from 2016 to 2022. Dr. Wang joined the Southern University of Science and Technology (SUSTech) as an assistant professor from Nov, 2022. Her lab mainly utilizes the single-molecule techniques such as single-molecule fluorescence, optical tweezers and smFRET to study the dynamic regulation of molecular machineries involved in transcription, replication and DNA repair. 

Research Interests

Life is carried out by a series of tiny molecular machineries. The central dogma of biology contains three basic processes: DNA replication, DNA transcription and protein translation. During each step, the enzyme that carry out the function must be strictly regulated to ensure proper cell growth. How these machineries can be assembled and regulated spatiotemporally is a key question for all the biological processes, as well as how their dysfunction contribute to disease. We will utilize the unique advantage of single-molecule techniques—real-time observation and simultaneous tracking of multiple components—to reveal the dynamic regulation of biological processes in response to different signals. Currently, we are interested in how the RNA polymerase can access and function on DNA substrate containing lesions, modifications or blocking proteins.
