Yuko Hasegawa’s doctoral research focused on developing a new imaging technique to see how microbial communities are organized, particularly inside the body. Her technique allows one to distinguish up to 11 different types of microbes in one fluorescence image, which led her to investigate the spatial distributions of bacterial cells in the gut of mice that were inoculated with bacterial types typically found in the human gut. Hasegawa’s imaging protocols will be useful for characterizing spatial organization of microbial communities in many different types of environmental and clinical samples. Her co-advisors were Gary Borisy (Yuko was his 24th student to graduate with a Ph.D.) and Mitchell Sogin of the Bay Paul Center; she defended her thesis on December 18.
The Brown-MBL Graduate Program attracts a diverse group of talented and dedicated students from around the world. Some students spend their first years taking courses at Brown and do not make their base at MBL full-time until their second or third year in the program. Other students remain based in Providence for the duration of their studies but work closely with one or more MBL scientists as they pursue their research. Still other students engage in research that requires them to be at the MBL from the start of their studies. Sixteen graduate students currently are enrolled in the program, ten students have graduated from the program with doctorates and four others have left early with a masters degree.
