Assist. Prof. Dr. Santosh Kumar | Cellular Senescence Aging | Best Researcher Award

Georgetown University | United States

Dr. Santosh Kumar is a cancer biologist with extensive experience in cellular and molecular oncology, particularly in understanding the molecular mechanisms that regulate cancer progression, therapy resistance, and tumor heterogeneity. His work integrates advanced 2D and 3D cell-culture systems, immunophenotyping, flow cytometry, and high-resolution microscopy to dissect tumor cell behavior in physiologically relevant contexts. With strong expertise in RNA–protein interaction assays, including EMSA and complementary biochemical approaches, he investigates post-transcriptional regulation and molecular signaling pathways that influence cancer stem cell dynamics and immune-related phenotypes within tumors. Dr. Kumar’s research has also focused on identifying biomarkers associated with tumor aggressiveness and exploring how stress responses and radiation exposure influence cancer cell survival and transformation. His postdoctoral and faculty-level research contributions have advanced the understanding of stem-like tumor cell populations and their role in therapeutic resistance. Through collaborative translational studies, he has contributed to projects aimed at improving diagnostic strategies and developing targeted interventions in oncology. Recognized through awards such as the Radiation Research Society’s Early Career Investigator Award and the NSBRI Post-Doctoral Fellow Presentation Award, Dr. Kumar continues to contribute to innovative cancer research with an emphasis on molecular mechanisms, immunophenotyping, and stem-cell-driven tumor biology.

Associate Professor Dr. Ali Esmaeili’s research primarily focuses on the psychological and cognitive dimensions of sports science and human movement behavior. His extensive body of work explores how emotional regulation, motivation, and social skills influence executive functions and overall well-being among students and athletes. Esmaeili has investigated the mediating role of emotional regulation in the relationship between social skills and executive functioning, as well as the cognitive benefits of game-based sports exercises for late learners. His studies also examine how sports participation enhances social identity and well-being, particularly among female students. Beyond educational contexts, Esmaeili’s research extends to clinical and developmental psychology, addressing topics such as attention-deficit/hyperactivity disorder, separation anxiety, and emotion regulation in families with children with autism. He has further contributed to understanding attentional bias modification, forgiveness therapy, and hypnosis as psychological interventions for improved mental health and performance. His publications span multiple interdisciplinary journals, bridging physical education, cognitive psychology, and behavioral sciences, highlighting his commitment to integrating psychological frameworks into sports and movement studies. Collectively, Esmaeili’s research advances knowledge in sport psychology, emphasizing emotional and cognitive development through structured physical activity and psychological skill training.
