Dr. Thomas' research interests are related to racial/ethnic differences in breast cancer and health disparities research.  Her clinical expertise is in cytopathology and breast pathology. Dr. Thomas published a textbook in 2010 on breast pathology targeting non-pathologist physicians and even the general public. She is internationally known for her expertise in cytopathology, particularly for her knowledge and skills in the Fine Needle Aspiration (FNA) cytology technique and breast FNA.
