My research interests are focused on clinical drug development in in breast cancer (BC). From 1992 to present I have been involved in 100+ phase 1-3 clinical trials and have served as the institutional principal investigator (PI) on the majority of the University of Maryland Greenebaum Comprehensive Cancer Center (UMGCCC) BC specific clinical trials. The UMGCC “Hormonal Sensitive Program” (BREAST and PROSTATE) was instrumental in the UMGCC receiving the P30 grant funding and the NCI Comprehensive Cancer Center designation in 2016. Our Clinical Breast Cancer Program contributes substantial numbers of patients to institutional and national/cooperative group clinical trials with rates of accrual much higher than the national average. In addition we also have excellent participation and accrual of minorities to our clinical trials, many of our trials have 40-50% AAF accruals. As the Director of UMGCCC Breast Evaluation and Treatment Program (BETP), a multidisciplinary program with commitment to comprehensive, multidisciplinary breast cancer care, I have been overseeing the clinical and research aspects of the program for several years. The UMGCCC clinical breast program continues to work in the area of clinical drug development with the focus on hormone resistance, role of microtentacles in breast cancer metastasis, the significance of brown adipose tissue in pathogenesis and progression of breast cancer, the GP-88 circulating marker and its significance in patients with breast cancer and in screening for breast cancer. In my role of the Director of the Breast Evaluation and Treatment Program at the University of Maryland Greenebaum Cancer Center I am wholeheartedly committed to the successful progress of our program and have the ability to facilitate breast cancer patient accruals to translational clinical projects.
