Our research group, formally known as the Physics of Soft Matter, Interfaces & Complex Systems (PhySICS) Lab, investigates the fundamental physics of fluid flow in complex environments. From stationary droplets to dynamically migrating cells, our work spans the study of passive systems, active matter, and the rich spectrum of biological flows—from the cellular to tissue scale. Our overarching objective is to uncover the underlying physical principles that govern these systems and translate this understanding into real-world applications. We integrate theoretical modeling, computational simulations, and exploratory experiments to study fluid behavior across a wide range of length and time scales in diverse complex systems. Our research is highly interdisciplinary, drawing on continuum mechanics, statistical physics, and soft matter theory to address challenges at the nexus of chemical engineering, physics, mechanical engineering, biology, materials science, and nanotechnology. Through this multifaceted approach, we aim to advance both fundamental knowledge and practical innovations in areas such as digital and droplet microfluidics, soft materials, healthcare, and energy systems. The lab is located in Room MB-314/2, Main Building, Department of Chemical Engineering, Indian Institute of Technology Kharagpur.
