Clinical Expertise

Dr. Rezaei’s clinical practice focuses mainly on Urologic pathology and Cytopathology.  In addition to the diagnostic services, she is an active member of multidisciplinary urologic oncology team.  As the Chief of Cytopathology, Dr. Rezaei provides diagnostic services in GYN and Non-GYN cytology, with emphasis on cytology based molecular assays in cervical cancer screening and bladder cancer.  She also accepts patients for performing Fine Needle Aspiration of thyroid, salivary gland, lymph nodes, and other superficial lesions with an additional certification from the College of American Pathologists in performing ultrasound-guided FNA. 

Research

Dr. Rezaei’s research focuses on biomarker discovery and prognostics of cancers and precancers.  Within the institution, she has worked with the researchers at the GW Genomic Medicine, on the biomarker identification and validation for the early diagnosis and treatment of breast cancer.  She has also collaborated in multi-institutional studies relating to bladder cancer biomarkers and genital squamous intraepithelial lesions.
