Active Project (Nanomechanical Characterization of Single Nanofibers and Associated Reinforcement Mechanisms)
This project aims to investigate the nanomechanical behavior of individual polymeric and composite nanofibers to elucidate their fundamental reinforcement mechanisms in advanced functional materials. By employing the technique of atomic force microscopy (AFM)-based nanoindentation, we will quantify key mechanical properties—including elastic modulus, adhesion force, and stiffness—at the single-fiber level. The study also explores the role of interfacial bonding, nanofiller dispersion, and fiber morphology in governing load transfer and failure mechanisms.
Active Project (Engineering Intervertebral Disc)
This project focuses on the development of biomimetic intervertebral disc (IVD) replacements that replicate the structural, mechanical, and functional properties of native discs. By integrating advanced fabrication techniques with biocompatible polymers and nanocomposites, we aim to engineer disc scaffolds capable of restoring load-bearing capacity, flexibility, and shock absorption in degenerated spinal segments. Finite element modeling and mechanical testing will be used to optimize design parameters and validate performance. The project ultimately seeks to advance clinically translatable solutions for treating chronic low back pain caused by disc degeneration.
Active Project (Engineering Prosthetic Sockets)
This project aims to develop next-generation prosthetic sockets that offer improved comfort, fit, and biomechanical performance for individuals with limb loss. By leveraging advanced materials, personalized digital modeling, and additive manufacturing, we seek to design custom-fit sockets that accommodate residual limb geometry, dynamic loading, and skin–socket interactions. The research incorporates pressure mapping, gait analysis, and finite element simulations to evaluate and optimize mechanical performance and user comfort. The ultimate goal is to enhance prosthetic usability, reduce skin irritation and pain, and improve mobility and quality of life for amputees.
Mar. 2025 – April. 2025 (National Science Foundation I-Corps Hub Northeast Region: Cohort Lehigh)
Jan. 2025 – Dec. 2025 (Engineering Anterior Cruciate Ligament Scaffolds)
This project focuses on the design and fabrication of biomimetic scaffolds for anterior cruciate ligament (ACL) regeneration, aiming to restore the structural integrity and mechanical function of damaged ligaments. Utilizing integration of multiple fabricating techniques, the engineered scaffolds will be designed to replicate the hierarchical architecture, anisotropic mechanics, and biological cues of native ACL tissue. Mechanical testing and computational modeling will guide scaffold optimization to promote load-bearing performance. The goal is to develop clinically viable ACL grafts.
