MMDOL Mission and Strategy:

This lab aims to create and optimize the microstructure of multifunctional materials using computational and experimental means. The objective is to optimally design materials and structures that meet certain functional requirements. Following are some of the research projects pursued in our lab:

  • Design of functionally graded materials with enhanced load carrying capabilities
  • Design of scaffolds and implants for bone tissue engineering
  • Optimization of applications catering to the field of bio-mechanics

The long term goal of this laboratory is to integrate computer aided engineering tools together with 3D printing technologies to build useful real world applications. Graduate and undergraduate students in our lab get trained in using CAD/CAM/CAE tools as well as in conducting hands on experimental tests.
