Clinical interests of Dr. Welsh are limited exclusively to caring for breast cancer patients. This includes patients with noninvasive and invasive early breast cancer; patients who require hormonal and chemotherapy in the adjuvant and neoadjuvant setting; locally advanced breast cancer patients; and patients at high risk for breast cancer due to premalignant breast lesions or strong family history.
Research interests of Dr. Welsh include investigating the cell biology of breast cancer growth. This includes intracellular signaling pathways that regulate the cell cycle and how they become autonomous or decompensated during the process of tumorigenesis, as well as the investigation of novel agents to correct these abnormalities. Other areas include the investigation of tumor markers that predict responsiveness to chemotherapy agents in order to target specific therapies to individual patients.

Dr. Welsh received her M.D. degree from the Medical College of Virginia, Virginia Commonwealth University and completed a residency in Internal Medicine at Case Western Reserve University Hospitals. During her residency, she was the recipient of an NIH training grant award to perform research on cell membrane signaling mechanisms. Based on her research, she was accepted as a Senior Staff Fellow at the National Institutes of Health in Bethesda, MD where she investigated the molecular and cell biology of intracellular signaling pathways. After moving to Florida, Dr. Welsh completed her clinical fellowship in Medical Oncology at the University of Miami. An Associate Professor of Medicine, Dr. Welsh is certified by the American Board of Internal Medicine. She has received numerous awards including a Young Investigator Award and a Career Development Award from the American Society of Clinical Oncology, and a Clinician Scientist Career Development Award from the National Cancer Institute of NIH. Her past laboratory research focused on the mechanism of autonomous growth of breast cancer cells and was funded by the NIH, the Breast Cancer Program of the Department of Defense, and the American Cancer Society. Her medical practice is devoted exclusively to the care of breast cancer patients at the Sylvester Comprehensive Cancer Center and Jackson Memorial Hospital.
