As a pathologist by training I possess considerable expertise in clinical and experimental pathology primarily related to the characterization of xenograft and transgenic/mutant mouse cancer models and animal models of non-neoplastic conditions such as autoimmune, metabolic diseases and tissue regeneration models. My postdoctoral training at Tulane University in the group of the Nobel laureate Prof. A.V. Schally also offered me the opportunity to perform bench research in experimental and neuroendocrine oncology/pathology. Among the topics of my research are the characterization of mouse models for cancer, stromal-tumor interaction, inflammation, autoimmune disorders such as pemphigus vulgaris and metabolic conditions such as diabetes and obesity. Recently, I have studied the significance of using deer mice as an alternative model for human breast cancer studies. I am also actively involved in research projects related to markers’ analysis of human cancers.
