Dr. Aejaz is a molecular cell biologist with a particular focus on novel cancer biomarkers. His research interests are focused on the mechanisms of cancer progression and development of refractory states with a special emphasis on cellular signaling, metabolism, targeted therapeutics and microvesicles.

Before joining Baruch S. Blumberg Institute, Dr. Aejaz Sayeed worked as a research faculty for more than six years in the Department of Cancer Biology at Thomas Jefferson University where he studied the molecular crosstalk between β1 integrins and insulin-like growth factor receptor. He received an American Cancer Society/IRG award for this work. Using in vivo conditional transgenic model systems of prostate cancer, Dr. Aejaz investigated underlying molecular mechanisms of radiation resistance and also dissected the role of exosomes in prostate cancer progression. At Thomas Jefferson University he taught courses on cancer signaling and metabolism in the graduate program of biochemistry and molecular Biology.

Dr. Aejaz worked as a research associate scientist at California Pacific Medical Center in San Francisco, where he specialized in creating a battery of primary breast cancer cell lines representing all histologic grades of the disease and investigated genetic signatures associated with cancer aggressiveness in an effort to discover and characterize novel molecular markers of the aggressive disease. While working in the Department of Pharmacology and Therapeutics at Roswell Park Cancer Institute Dr. Aejaz conducted a pioneering study in establishing the molecular interaction between tumor suppressor p53 and estrogen receptor in breast cancer which explained the compromised tumor suppression in p53 wild type tumors. Dr. Aejaz Sayeed received his Ph.D. from the Department of Experimental Medicine and Biotechnology, Post Graduate Institute of Medical Education and Research, Chandigarh and conducted his post doctoral studies in cancer biology at California Pacific Medical Center in San Francisco. Overall, Dr. Aejaz has made conceptual advances in connecting signaling to gene expression to aggressive phenotypes, and paved the way for new directions in biomedical research.
