Dr. Kitajewski is Director of the University of Illinois Cancer Center, a Professor in the Department of Physiology and Biophysics, and the Associate Director for Basic Research. His research is focused on tumor angiogenesis, cell fate determination, GPCR signaling and pathway remodeling. Specific areas of focus are vessel development, reproductive angiogenesis and tumor angiogenesis associated with breast and ovarian cancer. His lab has explored the Notch signaling cascade and determined how cell-fate determination mediated by Notch and VEGF guides the proper construction of the vasculature. His lab established that Notch functions in tumor angiogenesis, and they developed therapeutic strategies to treat gynecological malignancies and breast cancer. In 2016, he became Head of the Department of Physiology and Biophysics at University of Illinois Chicago (UIC) and Associate Director of Basic Science at the Cancer Center. He served as the President of the North American Vascular Biology Organization (NAVBO) and seeks to build strong networks of vascular biology researchers during his tenure. His leadership responsibilities while at Columbia University included acting as Co-Director of the Cancer Signaling Networks program at Herbert Irving Comprehensive Cancer Center (HICCC) and Director of the Division of Reproductive Sciences in the Department of Ob/Gyn. Kitajewski served as Charter Member for the Cardiovascular Differentiation and Development study section and has served on ad-hoc review panels for NIH and DOD research grants, program projects and training grant, and NCI intramural program research evaluations. A sizable portion of his activities have been in serving and strengthening the field of cardiovascular biology.
