Education
Dr. Xenos earned his medical degree from Aristotle University of Thessaloniki, where he received comprehensive training in clinical medicine and cultivated a strong interest in radiology and interventional oncology. He complemented his education by completing the United States Medical Licensing Examinations (Step 1 and Step 2), demonstrating proficiency in international medical standards. His early training was enriched with advanced suturing courses and certification in life support and emergency response, laying the groundwork for both his clinical and academic pursuits. He later expanded his expertise through a specialized Medical Statistics Program at Stanford School of Medicine, which strengthened his ability to conduct advanced data-driven research in radiology and oncology.
Experience
Dr. Xenos began his professional career as a resident in the Department of Diagnostic Radiology at Hippokration General Hospital of Athens, where he completed three years of rigorous clinical training. His residency not only provided hands-on experience in diagnostic imaging and patient care but also allowed him to contribute to the management of complex cases, including work in ICU and ICU-COVID departments. During his time in Greece, he actively volunteered in community clinics, offering essential medical services to underserved populations while mentoring medical students in research methodology. Currently, at MSKCC, Dr. Xenos plays an integral role in interventional oncology research, focusing on software-based ablation margin assessment, dosimetry analysis for trans-arterial Yttrium-90 treatments, and statistical analysis of outcomes in colorectal liver metastases. His multidisciplinary collaborations and involvement in high-impact procedures reflect his capacity to merge clinical practice with cutting-edge research.
Research Focus
Dr. Xenos’s research interests span diagnostic and interventional radiology, oncology, and evidence-based medicine. His work is particularly focused on minimally invasive image-guided therapies, including percutaneous ablation and embolization techniques for cancer treatment. He has led and co-authored numerous systematic reviews and meta-analyses that have influenced clinical decision-making in neurosurgery, interventional radiology, and oncology. His investigations into thrombectomy techniques, carotid artery webs, trigeminal neuralgia, and neurofibromatosis-associated tumors highlight his commitment to improving patient outcomes through critical synthesis of current evidence. His present research at MSKCC aims to refine ablation methodologies, optimize dosimetry, and establish best practices in interventional oncology for colorectal liver metastases.
Awards & Honors
Throughout his academic and professional journey, Dr. Xenos has been recognized with numerous distinctions. He received the Eurobank Scholarship for top ranking in Greece’s Panhellenic Exams, a prestigious honor reflecting his academic excellence. His early years were marked by consistent recognition from the Greek Ministry of Education for outstanding performance. He achieved 4th place in the inaugural Hellenic Student Olympiad of Pharmacology, further demonstrating his scientific aptitude. In addition to academic achievements, his leadership and discipline were honored at the Greek Military Medicine Academy, where he excelled as an Honorary Sergeant responsible for training and mentoring junior cadets.
