Applied materials — advancing mechanical metamaterials with imbeded functionality.
I’m a Postdoctoral Fellow in Mechanical Engineering @ Harvard University, working at the intersection of material science, metamaterials, mechanics, and fluid–metamaterial interactions.
My research explores how architected materials can modulate material properties - such as texture, stiffness, and aerodynamics - to enhance performance in applications ranging from sportswear to aerospace systems.
Beyond research, I’m passionate about mentoring early-career engineers and fostering interdisciplinary collaboration between materials, mechanics, and thermofluids.
Research Spotlight.
Our latest study, published in Advanced Materials, introduces a stretchable textile metamaterial capable of dynamically altering its aerodynamic drag by modulating surface texture in response to a uniaxial stretch. The auxetic textile can generate dimples even when tightly fitted around a body or object. The system demonstrates a new regime in fluid-metamaterial coupling, where mesoscopic unit-cell deformation is used to control aerodynamic properties.
“… textile dimpling opens promising avenues for surface roughness control of bodies or objects, offering exciting opportunities in fluid-dynamic optimization for aerospace, maritime and civil engineering systems.”
