Research in Professor Lin’s lab focuses on addressing fundamental technical problems related to directed evolution, and on applying the technology to engineering of various enzymes and bioprocesses. At present, there are three specific areas of research that we are pursuing: (1) development of tools for directed evolution, for example, a high thorough-put autolysis scheme for E. coli cells, and a method for protein shuffling; (2) evolution of useful biocatalysts and pathways, including proteins/enzymes related to biorefinery and for production of fine chemicals; (3) dissection and functional analysis of enzymes and viral proteins. Research in this lab has been supported by the national key basic research (973) program, the national high-tech (863) program, NSFC, and industrial grants. Prof. Lin also has been teaching two undergraduate courses “introductory molecular biology” and “principles and applications of genetic engineering”.
