EP and Pacing Lab Director | National and Kapodestrian University of Athens | Greece

Dr. D. L. Tsiachris is a highly accomplished cardiovascular researcher and clinician whose work has profoundly influenced the fields of cardiac electrophysiology and interventional cardiology. With an extensive research portfolio encompassing 224 scientific publications, 4,004 citations, and a Scopus h-index of 34, his contributions have advanced the understanding and management of complex cardiac rhythm disorders. His primary research interests lie in atrial fibrillation, ventricular arrhythmias, catheter ablation, and cardiac resynchronization therapy, with particular emphasis on novel energy-based interventions such as pulsed field ablation, cryoballoon technology, and radiofrequency systems. Dr. Tsiachris possesses exceptional research skills in clinical trial design, data synthesis, systematic reviews, and meta-analysis, enabling him to provide robust evidence supporting safer and more effective therapeutic strategies for patients with structural and electrical heart diseases. His investigations into leadless pacing systems, proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, and the optimization of device-based therapies have contributed to personalized and precision-based cardiology. In addition, his studies on patient-reported outcomes and long-term ablation success rates bridge the gap between procedural innovation and patient-centered care. Recognized for his scientific leadership and collaborative excellence, Dr. Tsiachris has co-authored with more than 700 international researchers and continues to influence clinical practice guidelines through his impactful findings. Though his work is primarily published in high-impact journals such as Heart Rhythm, Europace, and Journal of Clinical Medicine, his commitment to advancing cardiovascular science stands as his greatest distinction. Honored for his research excellence and global contributions to electrophysiology, Dr. D. L. Tsiachris remains a driving force in redefining the standards of modern cardiac care through innovation, precision, and evidence-based practice.

Dr. Shinichiro Sawa | Medicine | Best Researcher Award

Professor | Kyushu University | Japan 

Dr. Shinichiro Sawa is a highly accomplished Japanese immunologist and medical researcher renowned for his pioneering work in immune regulation, autoimmunity, and inflammation. He currently serves as a Professor at the Institute of Bioregulation, Kyushu University, Japan, where he leads innovative studies in molecular and cellular immunology. Dr. Sawa began his academic journey at Osaka University, earning his Medical Degree (M.D.) in 2000 and subsequently his Ph.D. in Medicine in 2006 from the same institution, where he developed a strong foundation in biomedical sciences and experimental medicine. His professional trajectory includes significant academic roles as Assistant Professor at the University of Tokyo (2011–2016) and Associate Professor at Hokkaido University’s Institute for Genetic Medicine (2016–2018) before joining Kyushu University in 2019. Dr. Sawa’s research interests center on understanding how immune cells, such as γδ T cells, fibroblasts, and plasma cells, interact with tissue environments to regulate immune tolerance, autoimmunity, and inflammatory diseases. His studies, published in prestigious journals such as Nature Immunology, Journal of Clinical Investigation, and Journal of Investigative Dermatology, have shed light on how fibroblasts contribute to central immune tolerance and how plasma cells promote osteoclastogenesis in autoimmune arthritis. His research skills encompass cellular immunology, molecular signaling analysis, animal modeling of immune diseases, flow cytometry, and translational immunopathology, demonstrating both depth and precision in experimental design and interpretation. Recognized for his scientific contributions, Dr. Sawa has received numerous academic honors and research recognitions throughout his career, reflecting his influence in the global immunology community. In conclusion, Dr. Shinichiro Sawa stands as a leading figure in immunological research, bridging basic science and clinical application to advance our understanding of immune homeostasis and to pave the way for novel therapeutic strategies against autoimmune and inflammatory disorders.
