My research lies at the intersection of materials science and biomedical engineering, with a particular emphasis on the synthesis, processing, and modification of advanced materials for healthcare applications.

 

  • Biomaterials:

    • I primarily work on the design, fabrication, and characterization of tissue engineering scaffolds and controlled drug delivery systems. It includes bioceramics (such as Ca-Mg silicates, calcium phosphates, and mesoporous bioactive glasses), biopolymer-based nanocomposites (chitosan, gelatin, alginates, and PLGA), ion-doping of bioceramics, 3D-printed scaffolds, and electrospun fibrous mats for bone tissue regeneration, wound healing, antibacterial, and antioxidant applications.

  • Surface Engineering:

    • My work in this area focuses on the surface modification of metallic biomaterials and alloys to improve wettability, corrosion and oxidation resistance, bioactivity, and biocompatibility. This involves developing protective coatings, anodization, and thin films on substrates such as titanium, nitinol, and stainless steel for biomedical implants and industrial applications.

  • Green Synthesis of Functional Ceramics:

    • My work in this area involves the green wet chemical synthesis of bioactive ceramics, primarily through sol-gel and co-precipitation techniques. Emphasis is placed on calcium phosphates, bioactive glasses, and silicate systems with controlled properties for improved biofunctionality and sustainability.

Previous Research: Earlier in my career, I worked extensively on Powder Metallurgy and Processing of metallic materials, particularly mechanical alloying and liquid-phase sintering, for the production of amorphous/nanocrystalline alloys, nanocomposites, and medical-grade alloys with tailored microstructures and properties.
