About

Dr. Sonal Gandhi is an Assistant Professor in the School of Computer Science Engineering and Technology (SCSET) at Bennett University. She earned her Ph.D. in Computer Science and Engineering from Delhi Technological University in 2025 under the supervision of Dr. Rajeev Kumar. Her thesis, “Development of Data Hiding Methods for Content Protection in Medical Domain,” focused on methods for protecting medical-domain content through data hiding. Her research spans reversible data hiding, medical-image security, image processing, computer vision and deep learning. DTU records identify her as a full-time Ph.D. scholar and DTU Fellow, and DTU’s 2024–25 timetable lists her teaching Compiler Design and laboratory classes.
