Summary

My research work focuses in two main areas.  First, I am actively developing and improving a group of histopathology-related technologies to support basic and translational research projects involving cell signaling, molecular carcinogenesis and animal modeling.  These approaches include immunohistochemistry, quantitative image analysis using Aperio technology and AQUA (a automatic quantitation platform for immunohistochemistry), laser capture microdissection, and other technologies.  Second, I provide extensive histological and histopathological support, including interpretation of results generated in human and experimental animal tissues, to FCCC investigators.


My long-term research interests include understanding the molecular mechanism of ovarian cancer initiation and development. Research projects completed or in progress include quantitative image analysis of biomarkers on ovarian cancer tissue microarrays,  molecular characterization of initiation and progression of ovarian cancer, including aspects of the fallopian tube origin hypothesis, mouse modeling of ovarian cancer, and studies of early mouse embryonic development.
