Areas of Interest:
Nano-tribology, Bio-tribology, Polymer tribology, Materials in Mechanical Design. In bio-tribology, our research focus is on finding new solutions to reduce the wear of the hip and knee implants, especially that of the polymer part. We have developed novel composites and texturing methods to address this issue. These research efforts are expected to increase the life of the joint implants after they are implanted inside human body. New machine for bio-tribology test was designed and fabricated at IIT Delhi, and the design was registered by the Indian Patent Office.
