Clinical ExpertiseAs Director of the UPMC Molecular Anatomic Pathology laboratory and member of the MAP Division, Dr. Nikiforova supervises all clinical, developmental and regulatory activities of the MAP laboratory and performs sign out of molecular tests in the area of solid tumors. Most of the molecular tests performed at the MAP laboratory provide either diagnostic information or predict response to targeted therapies for common cancer types such as lung, brain, colorectal, thyroid, and melanoma, among others. Dr. Nikiforova's specific areas of expertise are in molecular diagnostics of gliomas and in preoperative detection of malignancy in thyroid FNA specimens. In addition to the traditional molecular approaches, Dr. Nikiforova actively works on developing multi-gene molecular panels using next generation sequencing platforms.
Dr. Nikiforova is actively involved in national committees including Molecular Oncology Committee, College of American Pathologists (CAP) and Laboratory Practice Committee, American Thyroid Association (ATA). She is Chair-Elect for Solid Tumor Subdivision, Association for Molecular Pathology (AMP) and member of the AMP Program Committee.
Research InterestsDr. Nikiforova's research efforts are focused on the areas of molecular diagnostics in solid tumors. Her main directions are:
- studying microRNA dysregulation in cancer, with emphasis on identifying novel microRNA markers for thyroid cancer
- developing novel diagnostic and prognostic molecular markers for brain tumors
- developing next generation sequencing including multigene panel approaches and high throughput microarray analyses for molecular oncology
