Summary of Expertise:

Listed with other top experts in: 

Expert applied his physics background to understand tension-free hernia repair. He along with his surgeon colleagues proposed new methodology in development of meshes. He quantified the effect of abdominal forces on the implant and proposed a novel mesh. This novel mesh not only accommodates forces, but also decreases the foreign body reaction and makes the fixation easy. His team developed prototypes of the new product in less than 4 months and succeeded in achieving the proof of concept. Their novel product is racing towards provisional and full patent.

Expert investigated coupling and transport of light through whispering gallery modes in spherical particles. He employed spheres in the range of 3-20 micron range for WGM generation and transport. He used dye doped spheres to generate WGMs and employed passive spheres to characterize the transport of light in chains of spheres. He excited the dye doped spheres using focused tunable laser beam. He characterized coupling between size mismatched spheres. He developed samples of chains and bispheres using micromanipulation and imaging. He spatially selected the spheres of interest using in-house developed microscope and analyzed spectra using liquid cooled spectrometer. He also developed crystals using these spherical micro-particles by hydro-dynamic flow based techniques. He along with his advisor proposed new understanding of percolation of light in these crystals based on whispering gallery modes' coupling and transport.

He also explored polycrystalline opals for their optical properties. Though opals are always considered as single crystalline, in practice obtaining a single crystal opal is near impossible because of manufacturing defects. In general opals exhibit single peak in reflection mode arising from Bragg phenomena. In polycrystalline opals, he observed multiple peaks originating from reflections between the domains. The beauty of these crystals is that all the domains were in a single crystal but rotated orientations. These domains enable multiple reflections between the domains.
