Personal History:

Dr. Carey is an Assistant Professor in the Department of Microbiology and Immunology. As the Director of Student Summer Research and Community Outreach, Dr. Carey oversees and is responsible for medical student research activities, including electives, summer and year-off activities. He oversees recruitment to and advising for the School of Medicine's summer research programs for health professional, undergraduate and high school students. In his outreach roles within the OSR and as a co-chair on the President's Outreach Council, Dr. Carey explores research, mentoring and STEM (Science Technology Engineering and Math) educational opportunities for students at all levels and from broad backgrounds, on and off the UMB campus. In addition, Dr. Carey is the leader (P.I.) of an NIH/NCI-funded research program focused on increasing the understanding of factors that determine life and death decisions in lymphoma and in other cancers. His teaching activities cover both basic and special topics in immunology and oncology in the Graduate School and the Schools of Medicine and Dentistry. Dr. Carey is a member of the Center for Vascular and Inflammatory Diseases (CVID) and of the Greenebaum Cancer Center.

Research Interests:

Our long-range research interests are to explore the mechanism of programmed cell death in tumor cells and especially B-cell lymphomas, via death receptors and by chemotherapeutic agents. We are exploring the notion that controlled oxidation (Reactive Oxygen Species, ROS) can promote the selective targeting, processing and targeted destruction of critical growth and survival proteins. Our research combines multiple molecular, proteomic, metabolomic and fluorescence-based and proteomics-based approaches to potentially target protein kinases in the PI3K/Akt and Ras signaling pathways and to invoke protein phosphatases for the selective killing of lymphomas, prostate and breast cancer cells. Ultimately, gaining better understanding in this area will aid the design or screening of better targeted, more potent and less toxic therapies for the treatment of cancer.

Lab Techniques and Equipment:

RedOx biology, lymphoma, Reactive Oxygen Species, western blotting, Flow cytometry, molecular targeting, biochemistry
