February 5 Sima Setayeshgar Abstract Title: "Stripes, Spots and Scrolls: Some Problems in Pattern Formation"
	Pattern formation is a striking feature of many systems in nature, from animal and fish coat markings to evolving chemical patterns on catalytic surfaces to convection rolls in fluids. Despite having very different underlying microscopic descriptions, these systems can produce patterns with remarkable similarity. Scientific computation is an integral part of understanding the unifying principles of pattern formation in varied physical systems. In addition to complementing experiments, numerical simulation is necessary in describing these nonlinear phenomena, particularly under realistic conditions. I will discuss my work on, patterns addressing questions from chemistry and biology.
