Dr Ravi’s group work on biodegradable magnesium alloys for temporary implant applications and magnesium infiltrated additively manufactures Ti scaffolds for tissue engineering applications. His group members are involved in developing functional coatings for biomedical implants. Expertise in analyzing biocorrosion and stress corrosion cracking of biomedical implants is also available in his research group. Dr. Ravi's group is also involved in development of Mg based bulk metallic glass for biodegradable temporary implant applications.

Dust accumulation on the cover glass of solar panels from transport vehicles, industrial chimney wastes and pollution inhibits the incident light photons to reach the active part of the solar cell and consequently reduces the output electrical power. Dr. Ravi’s group has developed transparent scalable anti-reflective superhydrophobic self – cleaning coatings on solar panel cover glass to overcome this problem.

Superhydrophobic Coating for Biofouling
Ultrasonic melt processing is extensively used in Dr. Ravi's group for in-situ generation of nano particles and its uniform dispersion in Al alloys. Ultrasonic assisted grain refinement and porosity reduction in Al and Mg alloy has been achieved by his group members. Apart from this, ultrasonic treatment was utilized in Dr. Ravi's group for reducing the hot-tearing of Inconel 718 alloy during fusion welding process.

Alloy Design - Computational Thermodynamic Approach
Dr. Ravi's group has identified new thixoformable creep resistant Magnesium alloys using computational thermodynamic approach. For this purpose, phase equilibria for Mg-Al-Sr, Mg-Zn-Y and Mg-Sn-Y ternary alloy system was thermodynamically calculated based on CALPHAD approach and validated in the Mg-rich region. Recently, Dr. Ravi's group has explored the possibility of using computational thermodynamic approach in designing of new bulk metallic glass and High entropy alloys (HEA).
