UPCOMING TALKS
RESEARCH OVERVIEW
During my educational/professional training, I had an opportunity to work on different interdisciplinary projects related to polymer synthesis and intelligent biomaterials for drug and gene delivery, photodynamic therapy, and tissue engineering. I aim to develop an academic career in biomaterial science with immunomodulation capabilities to tune inflammation and infection in soft tissue repair. My educational degrees were focused on polymer and biomolecular chemistry, but later, my research interests shifted toward different forms of biopolymer scaffolds in regenerative medicine and drug delivery. I excelled in my postdoctoral tenures at the University of Alberta, Canada, researching porcine islet isolation and implantation with various biomaterials in immune-deficient mice. At the University of Nebraska Medical Center, I gained knowledge in fiber composed biomaterial engineering and clinical disease treatment from both engineers and physicians. These included out-of-cleanroom fabrication processes involving polymer and biological materials, micro-engineered cell transplant systems, and injectable cell/therapeutic carriers for tissue repair.
JJ lab’s at Terasaki Institute is focusing on the development of new forms of functional biomaterials systems for enhancing rapid tissue repair and regeneration. His team is focusing on different micro/nano engineering technologies like electrospinning, electrospraying, electrostatic flocking, and 3D printing to create various functional biomaterials (modular biomaterial, fiber reinforced scaffolds, and piezoelectric biomaterials) for wound healing, musculoskeletal tissue engineering, neural tissue engineering and hemostasis.
RESEARCH HIGHLIGHTS
Modular tissue engineering
Modular tissue engineering is a bottom-up approach used for fabricating building blocks of engineered biological tissues for regenerative medicine. The significant advantages of modular scaffolds are the ability to create specific geometry, and precise microarchitecture allows enhanced cell migration and vascularization. Our lab is focusing on the engineering the modular scaffolds (Granular gels, and aerogels ) by using electrospraying, microfluidics, and 3D printing for tissue repair and regeneration.
Fiber reinforced scaffold
Fiber-reinforced hydrogel composites recently gained attention with their unique fibrous structure mimicking native tissue architecture. Fiber-reinforced composites show enhanced mechanical strength and fiber-induced cell alignment in various cell studies. Our recent findings show that handheld 3D printers can print these composites without harming cell viability, enabling precise fiber alignment and in situ printing. In another study, we found that fiber reinforced bioink provides controlled release of growth factors for bone tissue engineering while providing mechanical strength.
Piezoelectric materials
Due to their distinctive capacity to transform mechanical stress into electrical signals and vice versa, piezoelectric materials are attracting attention in the field of regenerative medicine. In response to tiny mechanical stresses (e.g., breathing, heartbeat, blood flow, and mild bodily movements such as walking and running), piezoelectric materials accumulate charge and demonstrate corresponding electrical activity. This activity can be harvested for tissue regeneration purpose. Different materials, including PVDF, PLLA, ZnO, BaTiO3 and glycine crystals, exhibit remarkable piezoelectric properties. Our lab is focusing on engineering the various piezoelectric injectable biomaterials for both soft and hard tissue repair
Wound healing and management
Wound healing and management are advancing through several innovative approaches. Our lab is focusing on reprogramming the infection with the development of multifunctional antibacterials injectable dermal fillers to inhibit the biofilm formation and followed by reducing the inflammation, to enhance chronic wound healing. Our second project belongs to reprogramming inflammation through macrophage polarization offers a promising strategy to modulate the inflammatory response, ultimately leading to better healing outcomes in chronic wounds.
Musculoskeletal tissue repair
The skeleton (which includes bones, ligaments, tendons, and cartilage) and muscles that are attached to it make up the musculoskeletal system. In our lab we are engineering osteoinductive and osteoconductive scaffolds with guided bone regeneration. Moreover, we will be engineering the precise organization of cells inside the hydrogels for the volumetric muscle loss treatments. Additionally, we are engineering injectable granular scaffolds for both periodontal and cartilage tissue repair.
Neural tissue engineering
The nervous system is a crucial component of the body and damages to this system, either by of injury or disease, can result in serious or potentially lethal consequences. Restoring the damaged nervous system is a great challenge due to the complex physiology system and limited regenerative capacity. In our nerve repair project, an injectable biomaterials provides electrical cues at the injury sites in a minimally invasive way to accelerate the healing process. Additionally, our newly developed microfabrication technique allows us to create bioengineered nerve conduits that support nerve cell growth across damaged areas, potentially restoring function and sensation. In our cell therapy project we engineered precise orientation of PRs and RPE to mimic a three-dimensional cell niche, aiming to restore vision.
Hemostatis
Hemostasis is the mechanism that leads to cessation of bleeding from a blood vessel. Many attempts have been made to develop hemostatic material or scaffold to prevent blood loss. Our expanded 3D nanofibrous scaffold can be injected and expands at the site of injury, effectively limiting excessive bleeding. In our another project we engineer thermoresponsive shear-thinning hydrogels composed of a thermoresponsive polymer, and hemostatic silicate nanodisks, as minimally invasive injectable hemostatic agents. This innovative approach offers a promising solution for enhancing hemostatic efficiency.
