On May 11th, 2017, Professor Sarah Woodson from the Department of Biophysics of Johns Hopkins University came to our college for academic exchange. On the afternoon of 11th, Professor Sarah introduced the structure of RNA in the class of bioorganic chemistry, an undergraduate student, and described the three-dimensional structure and functions of various RNAs in a simple way.Besides learning the basic knowledge, the students had a more comprehensive understanding of the stability factors of the three-dimensional structure of RNA and the functions of special structures in various regions of life. On the morning of 12th, Professor Sarah brought us a report entitled "Ribozymes: folding fast and slow" at Huaxi 210. The report was presided over by Professor Zhou Xiang, and was listened to by Professor Fang Xianyang from Tsinghua University, Professor Huan Wang from Nanjing University and many graduate students and undergraduates. The report introduced the close relationship among RNA gene, three-dimensional structure and function in detail, especially the dynamic study on how RNA molecules fold into special three-dimensional structure. After the report, Professor Sarah gave good answers to some questions of teachers and classmates, and the academic exchange atmosphere was strong. Professor Sarah's research ideas are rigorous and clear, and the content is substantial and novel, which has benefited the members of the research group a lot.

Introduction of Professor Sarah Woodson: She received her Ph.D. in 1987 and studied under Professor Donald Crothers of Yale University. From 1987 to 1990, he worked as a postdoctoral fellow in Professor Thomas Cech's laboratory at the University of Colorado at Boulder. The main research fields include RNA and protein in intracellular complexes, and the X-ray hydroxyl footprint method was first applied to RNA research. In 1993, he won Pew Academic Award for Biomedical Science, Camille Dreyfus Academic Award for Teachers in 1995, was elected as an academician of American Association for the Development of Science in 2010, and served as the chairman of RNA Association from 2016 to 2017.
