Assist. Prof. Dr. Dimitrios Tsiachris | Medicine | Best Researcher Award

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. Hugh Sampson | Medicine | Best Researcher Award

Professor of Pediatrics | Icahn School of Medicine at Mount Sinai | United States

Dr. Hugh A. Sampson, MD, is a distinguished physician-scientist and pediatric immunologist best known for his pioneering contributions in food allergy and immunopathogenesis, and is currently the Kurt Hirschhorn Professor of Pediatrics and Director Emeritus of the Jaffe Food Allergy Institute at the Icahn School of Medicine at Mount Sinai. He earned a B.A. in Biology from Hamilton College in 1971, then obtained his M.D. from SUNY Buffalo in 1975, followed by a pediatric residency at Northwestern University / Children’s Memorial Hospital and an allergy/immunology fellowship at Duke University (1978–1980). Over his career, he has held leadership roles including chairing the Section on Allergy & Immunology of the American Academy of Pediatrics, serving as past President of AAAAI, holding editorial board positions in leading allergy/immunology journals, and directing national food allergy research consortia. His research interests encompass the pathogenesis of food-induced anaphylaxis, the molecular and immunologic characterization of allergenic food proteins and epitopes, genetics and immune regulation in food allergy, development of precision diagnostics (e.g. epitope-specific IgE/IgG4 profiles), and immunotherapy strategies (oral, epicutaneous, sublingual, and biologics such as anti-IgE) as well as novel therapeutic approaches. His research skills include translational and clinical trial design, immunologic assays (e.g. epitope mapping, serologic biomarkers), mechanistic in vitro and in vivo models, bioinformatics integration, large cohort epidemiologic and registry studies, and mentoring interdisciplinary teams. Among his many awards and honors are election to the National Academy of Medicine (Institute of Medicine) in 2003, the Brett Ratner Award from the American Academy of Pediatrics, the Distinguished Scientist Award of AAAAI, memberships in honorary societies (Alpha Omega Alpha, Sigma Xi), and repeated recognitions from Research.com as a top immunology scientist. According to his institutional profile, his h-index (based on Scopus/Pure) is listed at ~85,982 (which appears anomalous and may reflect internal counting metrics), while bibliometric sources more conservatively report an h-index of ~147 with over 800+ publications; traditional citation counts exceed 100,000 across his work. In conclusion, Dr. Sampson’s career exemplifies a remarkable integration of basic immunology and clinical translation: his leadership, mentorship, and sustained high-impact scholarship have shaped the modern field of food allergy research, spawning diagnostic and therapeutic innovations and training generations of investigators in allergy and immunology.
