    Research Interests:

    • Additive manufacturing
    • Design optimization
    • Orthopaedic biomechanics
    • Orthopaedic implant design and analysis


    Innovative techniques like design optimization and multi-material additive manufacturing offer the possibility of crafting personalized implants that meet the unique requirements of individual patients. By tailoring attributes such as size, shape, and stiffness of the implant, it can more effectively integrate with the bone and expedite the recuperation process. This approach increases the chances of a full recovery and a better quality of life for the patient.


    Injuries or damage to the skeletal system can result in weakened biomechanical strength, leading to early disability and a lower quality of life for patients. Conditions like osteoporosis-related fractures, bone loss, or defects caused by trauma can also create a significant financial strain on the healthcare system. Despite improvements in implant design, treatment techniques, and regenerative medicine, treating bone deficiencies remains challenging for surgeons, often resulting in unsatisfactory clinical outcomes.
