Biography
Hesper trained as physicist in both her undergraduate studies (Caltech, B.S. Physics, 2005), and her graduate studies (UCSF, PhD, Biophysics, 2011). She did her graduate work with the late Mats Gustafsson at UCSF and Janelia Farm. In his group, she developed a nonlinear form of Structured-Illumination Microscopy. Afterwards, wanting to explore a biological phenomenon she did her postdoctoral work with Eric Rubin at the Harvard School of Public Health where she became fascinated by the ability of genetically identical organisms to display different phenotypes. This phenomenon is especially important for the treatment of tuberculosis, a disease caused by the bacterial pathogen Mycobacterium tuberculosis. She is excited to start a research group at the intersection of these two areas: the application of advanced light microscopy techniques to investigate the strategies mycobacteria use to survive the stresses imposed by antibiotics and host.
