My research is generally focused on analyzing the intercellular interactions of somatic cells within the mouse ovarian follicle and the oocyte-somatic cell interactions. I mostly study this by translating serial section electron micrographs to three-dimensional models.

I am a Research Associate in Mark Terasaki’s lab.  My primary project involves using serial section SEM to study cell-cell and cell-matrix interactions in articular cartilage and between articular cartilage and subchondral bone. I also assist with other projects in the lab as needed and with general lab responsibilities.

Gap junctions are specialized connections that effectively join two cells together and allow for the passage of small components between cells such as ions or metabolites.  Gap junctions are present between nearly all the cells of our body, and affect how most of our organs work.  Invertebrate animals also rely on gap junctions for many processes.  When gap junctions are no longer needed to connect cells, they get internalized into one of the two cells they connect, forming a double-membrane vesicle.  I am interested in whether gap junction internalization is biased in one direction or another and whether internalized gap junctions have functions in the cytoplasm before they get degraded.   One way I plan to investigate these questions is by combining serial section electron microscopy and immuno-labeling of proteins.

I am interested in studying the ultrastructure of the glomerulus using serial section electron microscopy methods. I am particularly interested in the structure of "dead ends" within the glomerular capillary network and their implication in renal physiology.

I am currently a postdoctoral fellow in the Jaffe and Terasaki labs. In the Terasaki lab, we are investigating the three-dimensional structure and length of the odontoblast processes, using serial section electron microscopy. My preliminary results indicate that this method will allow us to resolve 2 controversies in the field, concerning whether the odontoblast processes reach all the way through the dentin, and whether nerves are present in dentin.
