Adventures of a curious scientist: Self-Assembly of Water Drops to Optics of Butterflies and Beetles
ORAL
Abstract
In our studies we focus on the physics and chemistry of soft condensed matter, materials that are easily deformed by external forces; external stresses, electric or magnetic fields and not to mention thermal fluctuations. Typical materials that are considered to encompass soft matter include liquid crystals, colloids, and polymer solutions along with a host of biological materials. Such materials possess structures which are much larger than atomic or molecular scales; the structure and dynamics at mesoscopic scales determine the physical properties of these materials. We use optical methods, mostly various forms of light microscopy and scattering to study and understand such soft materials. In this talk, I will provide two such examples using structure formation in polymer solutions and structural color in biology. These were things, the Dillion Award winner for 2023, worked on while a student at the Georgia Institute of Technology
