Given the rise in obesity and an increase in the average life-span of people in the United States, surgeries involving total joint replacements (TJRs) such as knee and hip-replacement have nearly doubled between the years of 1992-2010. The success of TJR surgeries relies primarily on the skills of the surgeon in removing skeletal tissue and in shaping the bone. This research looks at the fundamental issues that affect the morphology of the bone surface during the surgery.

Graphene-based Lubricants for Micro-machining

The life-cycle of high performance micro/meso-scale parts such as missile bearings depends greatly on the surface integrity of the machined surface and the residual stresses in the part. These are in-turn a strong function of the cutting forces and temperatures encountered during the micro-machining operation. To address this challenge, we are exploring the effective use of nano-scale additives to improve the cooling and lubrication performance of cutting fluids used in micro-scale cutting applications.

Hierarchical fiber-reinforced soft-composites (HFrSCs) are composites made up of polymeric fibers (with specific material properties and hierarchical length-scales) embedded within a soft polymer matrix. This project involves fundamental research directed towards developing 3D printing processes for these composites. The research findings will enable the development of a reliable and scalable 3D printing technology for such composites, leading to the creation of a new market-segment for 3D printers. It will also facilitate innovations in fields such as bio-inspired materials, embedded sensing, and 4D printing (3D printed products with shape-memory properties).

Novel 3D Printier for Surgeon Training
This project aims at developing novel 3D printing technologies to print artificial body parts for surgeon training. The successful development of these manufacturing processes will ensure a reduction in the use of animal models and will also enable surgeon training for patient-specific surgeries. The 3D printing technology also has broader applications to the manufacture of hierarchical polymer composites.
