Research in our laboratory is primarily focused on translational pathology with multiple areas of interest which include molecular pathology, digital pathology, comparative pathology, biomarker development, drug discovery and development, drug safety, and genetically engineered mouse development. Our primary focus is to provide mechanistic insight into the tissue level interpretation of human diseases by comparing similar changes in appropriate models of diseases.
The laboratory provides digital image analysis of tissue sections for oncology research, especially immuno-oncology and validation of animal models of human diseases. We also develop and validate tissue biomarker assays for multiple tumor types, especially mouse tumor tissue immunophenotyping. Our collaborative research initiative has been instrumental in clinically translatable research programs on immuno-oncology and is also a driving force for the advancement of digital image analysis in this field.
Our laboratory is also interested in personalized medicine and immune-oncology. Related to these areas, our laboratory asks questions about the tissue/stroma distribution pattern and percentage of different immune cells types and their relevance to immune response against tumor tissue. Some of these questions are: 1) Is there a difference in drug response to difference in pattern of immune cell type distribution, stroma versus tumor infiltrating immune cells, and 2) What is the value of immunophenotyping of tumor and stroma infiltrating immune cells, and how do they differ in drug response to different therapeutic candidates? These questions will assist in accelerating personalized medicine.
