Research:
My lab focuses on understanding how the mammalian nervous system remodels itself during the lifetime of an animal.  We study synaptic and axonal rearrangements by first watching structural changes in living mice using a combination of fluorescence and confocal microscopy.  We next target these exact same synapses for a complete serial section transmission electron microscope (ssTEM) reconstruction.  This technically challenging approach permits highly resolved ultrastructural data from electron microscopy to be interpreted in a macroscopic and potentially dynamic context.  Such correlated imaging is particularly difficult in complex tissues where a cell that was previously imaged by light microscopy has to be distinguished from numerous similar, but irrelevant cells.  To make the process more routine, we developed a technique named “near-infrared branding” which uses a femto-second pulsed titanium:sapphire laser to create fiduciary “branding” marks in defined three-dimensional positions within glutaraldehyde-fixed tissue.  These markings restrict the reconstructed volume making correlated imaging much more feasible and reliable.  We are currently using correlated light and electron microscopy to study developmental synapse loss, axon loss in neurodegenerative disease models, and synaptic aging.
