About

Ranjan Gupta is an astronomer and educator dedicated to expanding access to observational astrophysics through innovative, low-cost instrumentation. His key research areas include variable star astronomy, transient follow-up observations, and the development of robotic telescope systems for university education. Gupta's most notable contribution is his leadership in the U-SmART (Small Aperture Robotic Telescopes for Universities) initiative, which brings together multiple institutions to design and deploy compact, fully robotic telescopes. These systems are specifically intended for student use, enabling hands-on learning in time-domain astronomy—from monitoring variable stars to rapidly responding to transient events like supernovae or gamma-ray bursts. By focusing on affordability and simplicity, Gupta’s work has made professional-grade robotic observing accessible to universities with limited resources, fostering the next generation of astronomers. His papers on the U-SmART concept, each cited over 20 times, have helped shape the conversation around small-telescope networks in education. Through this project, Gupta has demonstrated that even modest apertures can yield significant scientific and pedagogical value, empowering students to contribute real data to ongoing astronomical surveys.
