Research Interests: Soft Matter Physics, Biophysics, Mechanics of Living Systems, Active Matter, and Nonequilibrium Statistical Physics Our research seeks to understand how complex many-body systems self-organize, adapt, and evolve far from equilibrium. We aim to uncover the physical principles governing collective behavior across a broad range of systems, from living tissues and cellular assemblies to active and driven soft materials. A major focus of the group is the mechanics of living systems. We investigate how cellular-scale processes such as growth, division, motility, and mechanical interactions give rise to emergent tissue-scale properties and functions. By combining computational modeling with theoretical analysis, we study phenomena including tissue morphogenesis, collective migration, mechanical regulation of tumors, and the interplay between cellular activity and tissue architecture. More broadly, we develop minimal computational and theoretical models that bridge multiple length and time scales. Our work seeks to identify general principles governing rigidity, flow, pattern formation, and self-organization in nonequilibrium systems. To this end, we employ a range of approaches, including three-dimensional vertex-based models such as the Graph Vertex Model (GVM) and coarse-grained theoretical frameworks. A recurring theme of our research is the use of simple physical arguments or models to interpret complex computational results and reveal the essential mechanisms underlying emergent behavior. Beyond biological systems, we are interested in active matter, glassy dynamics, liquid-crystalline materials, lipid membranes, and driven polycrystalline solids. By exploring connections between living and non-living matter, we seek to uncover universal principles that govern collective dynamics in complex systems.
