Prof. Reddy’s research interests include structural masonry, mechanics of materials, energy in buildings, green buildings, low carbon construction materials, low carbon binders, geopolymer products and recycling solid wastes into construction materials. The translational R&D, innovations/technology development and out-reach activities touch upon: machines for compacted earth blocks (CEB), optimum soil grading curves for CEB, test methods for durability of CEB, cement-soil mortars, fly ash bricks, alkali activated bricks, rammed earth structures, alternative roofing systems. The translational R&D is of direct relevance to the industry and practiced by many building professionals resulting in >3 million tons of carbon savings. His nurturing efforts in dissemination of sustainable technologies touch the bottom of the pyramid cadres and many entrepreneurs. Prof. Reddy is responsible for establishing a centre for capacity building in sustainable technologies at the IISc new campus.
