Upcoming Seminars This Friday Dr. Barry Stoddard from the FHCRC will visit WWU and give a seminar entitled: "Homing endonucleases: reagents for gene targeting" as part of the Chem Dept seminar series. The Stoddard group website is: On Wednesday, an alumnus of the biology department who is now a leader in the field of microbiology and chemical communication in bacteria will be presenting his work (4 p.m., BI 415). Pete Greenberg is a professor and past chair at the Dept. of Microbiology at the University of Washington. A The research in Dr. Greenberg’s laboratory is focused on the emerging field of sociomicrobiology. He is principally concerned with three aspects of sociomicrobiology: I. The biochemistry and molecular biology of environmental sensing and response in bacteria with a particular emphasis on a form of chemical communication between bacteria termed quorum sensing. II. The mechanisms by which bacteria switch from a nomadic existence to a sessile biofilm lifestyle and the mechanisms underlying the ability of biofilm bacteria to survive the action of antibiotics. III. The ways in which clonal populations of bacteria can discriminate themselves from other clonal populations. All of these phenomena are of importance in pathogenesis.
