Personal History:

Dr. Staats practices anatomic pathology at University of Maryland Medical Center, with a focus on cytopathology and gynecologic and breast pathology. His research interest focus primarily on improving the diagnostic practice of pathology, particularly in cytopathology and gynecologic pathology, through refinement of morphologic criteria and use of ancillary testing.

Dr. Staats trained in Anatomic and Clinical Pathology at Massachusetts General Hospital in Boston, MA from 2003-2007. He completed the Robert E. Scully Fellowship in Gynecologic and Obstetric Pathology, including an embedded cytopathology fellowship, at Massachusetts General Hospital in 2009. He has been at the University of Maryland Medical Center since 2009.

Research Interests:

The primary focus of Dr. Staats's research is on improving the precision of pathologic diagnoses of cancer on cytology specimens and in the gynecologic tract. His focus is on refining the morphologic criteria used for categorization of malignancy, advancing ancillary testing patterns, and improving laboratory quality and efficiency practices.

Dr. Staats is a member if the Hormone Responsive Cancers Program within the University of Maryland Marlene and Stewart Greenebaum Cancer Center Program in Oncology. As such, he collaborates with both clinical and basic research investigators to develop innovative approaches to diagnosis, treatment, and prevention of breast cancer, gynecologic cancers, and prostate cancer.

As co-director of the University of Maryland Marlene and Stewart Greenebaum Cancer Center Pathology and Biorepository Shared Service, Dr. Staats provides important consultation and collaboration with clinical and basic researchers studying cancer in human tissue specimens.
