Research

Dr. Balakrishnan’s research focuses on gynecologic pathology, with particular interest in the relationship between tumor morphology, immunophenotype, and molecular alterations. His work is grounded in questions that arise from routine diagnostic practice, especially in areas where morphologic findings and ancillary testing may not fully align.

His goal is to bridge microscopic observation and tumor biology, using each to inform the other. Through this approach, Dr. Balakrishnan seeks to refine diagnostic interpretation, contribute to evolving classification systems, and identify practical biomarkers and histologic features that may have clinical relevance.
