Scientific Interests and Work
Soda-lime glass (SLG) is the most prevalent type of glass and accounts for about 90% of total manufactured glass.
Because of its resoftening and remelting properties, it is ideal for glass recycling and other engineering applications, where it may be subjected to high velocity impact. Therefore, understanding how this material responds to shock impacts is critical to any design and engineering effort. Dr. Subedi’s work focuses on obtaining information about the Hugoniot Elastic Limit (HEL) through measurements of its optical property and material topology changes of SLG under static and dynamic response experiments. His work insights into the discrepancies between convex downward curvature at low pressure and concave upward curvature at high pressure of the Hugoniot in SLG.
Dr. Subedi received his Ph.D. in Applied Physics from Mississippi State University in 2016. His dissertation research focused the development of new techniques in digital holography for micro-particle characterization. This work focused on the extraction of particle surface-texture from holographic images formed with backscattered light as opposed to forward scattered light, as is more commonly done. After concluding his degree, he joined Dr. Ariunbold Gombojav research group at the same university as a postdoctoral research associate and worked on integrating digital holography with confocal Raman spectroscopy for chemical and morphological characterization of micro-particles. Dr. Subedi joined ISP as a postdoctoral research associate in August 2018.
