About Me


MD, Aristotle University of Thessaloniki; PhD, Rosalind Franklin University of Medicine and Science


Clinical and Diagnostic Immunology - Rosalind Franklin University of Medicine and Science

I am an immunologist with a specialty in medical laboratory immunology. I have 15 years of experience in developing and validating immunoassays (tests) to diagnose immune diseases in patients. This includes autoimmunity, immunodeficiency, and tumor immunologic diseases.

My area of expertise is flow cytometry. This specialized laboratory technique is used to detect cellular and other changes in immune cells. Using these methods, doctors can diagnose abnormal immune cells that might be cancerous and see how well immunotherapies (a form of cancer treatment that uses the immune system to attack cancer cells) are working. I am particularly interested in intracellular cytokine assay by flow cytometry. This method is used to monitor T cells after blood stem cell transplantation

In my research, I am interested in natural killer (NK) cells and their role in protecting people from cancer. My goal is to develop flow cytometric assays to measure NK cell function as it relates to tumor immunology. NK cells are also used for immunotherapy. Chimeric antigen receptor NK (CAR-NK) cells are being engineered for cancer treatments. NK flow cytometric assays can help identify unique markers in CAR-NK cells.

Outside of the office, I enjoy spending time outdoors with my wife and two children. Hiking and swimming are among our favorite activities. I also enjoy cooking.
