I am an electron microscopist in the department of Molecular and Cellular Physiology in the Stanford University School of Medicine.  I am also part of the Smith lab at Stanford University. I use a JEOL 1230 TEM at the  Cell Sciences EM facility in the Beckman Center.

        I have studied the ultrastructure of many types of animal cells including sea slugs Aplysia and Hermissenda, Drosophila (fruit fly), squid Loligo pealeii, mouse, rat, frog Xenopus laevis, zebrafish Danio , firefly Photinus as well as human  cells. 

             Recently I have been looking at the ultrastructure of developing synapses in the zebrafish optic tectum and developing special staining techniques for neural circuit reconstruction using block face SEM developed by Winfried Denk .

  I am part of a collaborative effort with Project Brainstorm involving labs from Harvard, MIT and Stanford to study the wiring circuitry of the brain.
