Yuko Hasegawa is a fifth-year graduate student from the MCB Graduate Program. At the MBL, Yuko is advised by Drs. Gary Borisy and Mitch Sogin. She is developing an imaging technique to analyze micron-scale spatial distribution of a synthetic human gut bacterial community using a mouse model. Yuko is particularly interested in simultaneously analyzing multiple target bacterial groups (1) by using a molecular biology technique called fluoresce in situ hybridization (FISH) to fluorescently label specific bacteria of interest and (2) by performing spectral imaging analysis of fluorescent dyes.
