I am currently serving as a Distinguished Professor in the Department of Computer Science at Vidyasagar University, Paschim Medinipur, India. My academic journey began with a B.Tech. and M.Tech. in Computer Science and Engineering from the University of Calcutta, followed by a Ph.D. from Vidyasagar University. Each stage of this journey strengthened not only my technical foundation but also my commitment to teaching and research. Over the years, my research interests have centered on Image Processing, Steganography, Data Hiding, and Digital Watermarking. I have always been fascinated by the challenge of protecting digital information without compromising its quality or usability. Much of my work explores how data can be securely embedded, transmitted, and authenticated in an increasingly connected world. Guiding research scholars has been one of the most fulfilling aspects of my career. Four of my Ph.D. students have successfully completed their doctoral degrees under my supervision, and eight more are currently pursuing their research. Working closely with them—discussing ideas, solving problems, and celebrating milestones—remains a deeply rewarding experience. My research contributions are reflected in more than ninety-five publications in reputed national and international journals and conference proceedings. I have also had the opportunity to present over thirty-five research papers at international conferences in countries such as Japan, Thailand, and Dubai. These experiences allowed me to exchange ideas with global researchers and bring fresh perspectives back to my department. In addition, I have been invited to deliver talks and serve as a resource person in various seminars and academic programs, where I enjoy sharing knowledge and learning from diverse audiences. Beyond research and teaching, I have taken on several academic leadership roles at Vidyasagar University. I served as the Head of the Department of Computer Science for eight years, a period during which I worked closely with colleagues to strengthen academic programs and research culture. Earlier, I held the position of Teacher-in-Charge at HIT, Haldia. I am also a member of the Executive Council of Vidyasagar University, contributing to important decisions that shape the institution’s future. My engagement extends beyond the classroom and research laboratory. As the Program Officer of NSS Unit VIII, I remain involved in community-oriented activities that connect students with social responsibility. Within the department, I serve as the Secretary of the Ph.D. Committee, helping guide research policies and academic standards. Throughout my career, I have tried to balance research excellence, academic leadership, and community engagement. More than titles or numbers, what matters most to me is the opportunity to mentor students, collaborate with colleagues, and contribute meaningfully to the academic community.

My academic journey in Computer Science has grown naturally from curiosity into a deep commitment to building secure and intelligent digital systems. Over the years, my research interests have evolved across multimedia security, reversible data hiding, digital watermarking, artificial intelligence, fuzzy systems, IoT security, and smart applications. What connects all these areas is a simple concern: how can we protect information while making our systems more intelligent and trustworthy? A significant part of my work focuses on reversible data hiding, especially for sensitive domains such as medical and forensic imaging. In these fields, even a minor distortion can be unacceptable. I have worked on embedding techniques that preserve image quality while allowing complete recovery of the original data. The challenge has always been balancing capacity, security, and fidelity. Each solution demanded careful experimentation and refinement, but the goal remained constant—to design systems that are both practical and reliable. Closely related is my work on digital watermarking and multimedia authentication. With the rapid rise of image manipulation and deepfakes, ensuring authenticity has become crucial. My research explores fragile and robust watermarking schemes for tamper detection, localization, and recovery. I am particularly interested in combining classical signal processing methods with intelligent models to make authentication systems more adaptive and resilient. In recent years, artificial intelligence has become central to my academic direction. I have worked on fake news and fake image detection, integrating machine learning with semantic and fuzzy reasoning techniques. AI, to me, is not just about automation; it is about building systems that can learn patterns, interpret uncertainty, and assist human decision-making. I believe AI must be developed responsibly, especially in areas that influence public opinion and social trust. My research also extends to optimization under uncertainty using fuzzy models. Real-world problems rarely follow exact mathematical rules. Whether in logistics, resource allocation, or sustainability planning, uncertainty must be acknowledged and modeled carefully. Soft computing approaches allow us to design solutions that reflect practical complexity rather than ideal assumptions. Recently, I have explored IoT security and smart agriculture applications, including AI-based crop health monitoring systems. Technology should not remain confined to laboratories; it should improve everyday life. Designing secure, lightweight systems for interconnected devices remains an important direction for me. Overall, my academic interest lies in integrating security, intelligence, and societal relevance. I aim to contribute to a future where digital systems are not only powerful but also dependable, ethical, and human-centered.
