Our work lies at the intersection of soft matter science, colloids, polymer physics, and sustainable materials engineering. We explore how molecular structure, self-assembly, and external stimuli influence the rheological and structural properties of complex systems. By combining rheology, and scattering techniques (SAXS, WAXS, and SANS), we aim to unravel the fundamental principles that govern flow, deformation, and texture in soft condensed matter.

A central focus of our research is on lignin valorization—transforming this abundant and underutilized biopolymer into high-value materials. We are developing lignin nanoparticles, biofuels, and biolubricants. This work aligns with the global push for ecology, environment, and sustainability, seeking to reduce dependence on petroleum-based resources.

Our group also investigates stimuli-responsive systems such as electrorheological fluids and shear-thickening suspensions, which offer tunable flow properties under applied fields or stresses. Such systems hold promise for smart damping, protective gear, and adaptive engineering materials.

By bridging fundamental science and application-driven innovation, our goal is to design materials with controllable mechanics and sustainability at their core, paving the way for next-generation technologies in polymers, lubricants, and renewable energy.

I welcome motivated students, researchers, and collaborators from academia and industry to engage with our Soft Matter and Sustainability research group. Whether you are interested in joining the team or exploring collaborative opportunities, please feel free to get in touch.
