Extended Bio

Ranjini Bandyopadhyay is fascinated by the physics of everyday materials — the complex fluids, soft solids, and granular systems that surround us but resist simple description. She is a professor and chair of the Department of Soft Condensed Matter at the Raman Research Institute, a leading research institution in Bangalore that has been at the forefront of Indian science for decades.Her journey in physics began with a PhD from the Indian Institute of Science in 2001, where her doctoral work was recognized with the Marten Foster Gold Medal for the best thesis in the Division of Physical Sciences — a mark of exceptional research quality that set the stage for her career. She then moved to the United States for postdoctoral research, first at the University of California, Los Angeles (UCLA) and then at Johns Hopkins University in Baltimore, Maryland. These experiences exposed her to world-leading research environments and shaped her approach to experimental soft matter physics.Her research focuses on soft condensed matter — a field that studies materials that are neither simple solids nor simple liquids but something in between. This includes complex fluids like polymer solutions and surfactant mixtures, colloidal suspensions, and granular materials like sand and powders. She is particularly interested in how these materials flow, deform, and respond to external forces — a field known as rheology. Her work combines careful experimentation with theoretical understanding, probing the microscopic origins of macroscopic behavior.She has been recognized for her contributions to science through her election as a Fellow of the Indian Academy of Sciences. She is also a founder-alumna of the Global Young Academy, Berlin — an international organization that brings together early-career researchers from around the world to address global challenges. She serves on the editorial and advisory boards of several prestigious research journals, helping to shape the direction of scientific publishing in her field.As an author for ENTECH Magazine, Ranjini shares her deep understanding of soft matter physics and her perspective on scientific research, education, and the life of a working scientist in India. She writes for the physics student exploring their research interests, the aspiring scientist navigating a career in research, the educator looking for ways to make complex physics accessible, and anyone curious about the strange and wonderful behavior of soft materials.
