Dr. Rajesh Kumar

Dr. Rajesh Kumar is an Assistant Professor in the Department of Mathematics and Statistics at Deen Dayal Upadhyay Gorakhpur University (DDU GU), Gorakhpur, India. He is an active researcher in the field of theoretical and mathematical astrophysics, with a focus on relativistic stellar structures and alternative theories of gravity. His research primarily explores the mathematical astrophysics, including Compact stars, Black hole and other dense stellar configurations, within the framework of general relativity (GR) and modified gravity theories. He has contributed significantly to understanding- (i) a new end-stage of collapsing massive stellar objects (ECO-Eternal Collapsing Phenamenon), (ii) how deviations from standard gravitational theory (GR) influence the physical properties of compact stars- density, pressure anisotropy, and mass-radius profile, etc.

Dr. Kumar has authored numerous research articles in reputed international journals and continues to supervise PhD and master students, guiding them in advanced topics of gravitational physics and astrophysical modeling. His work emphasizes a strong combination of analytical/numerical techniques and physical interpretation, making meaningful contributions to contemporary astrophysical research.

In addition to his academic work, he is actively involved in science popularization and outreach activities, promoting scientific temper and encouraging young students to engage with fundamental concepts in mathematics, physics and basic sciences. He is also interested in exploring scientific perspectives within the Indian Knowledge System (IKS), aiming to connect traditional knowledge with modern scientific understanding.

Dr. Kumar is committed to fostering a collaborative and research-oriented academic environment, contributing both to scientific advancement and the development of future researchers in the field.
