### About Me

The research of Michael Siegel is focused on the analysis and numerical computation of moving boundary problems in fluid mechanics, materials science, and biology. His research interests include singularity formation on interfaces, the dynamics of drops and bubbles, and the development of numerical methods for interfacial flow with soluble surfactant. He is also developing efficient, nonstiff boundary integral methods for 3D interfacial flow with surface tension.

- Moving boundary problems in fluid mechanics, materials science, and physiology
- Scientific computation

The research of Michael Siegel is focused on the analysis and numerical computation of moving boundary problems that arise in fluid mechanics, materials science, and physiology. His research in fluid dynamics covers singularity formation on interfaces for inviscid and low Reynolds number (Stokes) flow, the dynamics of drops and bubbles (including the influence of surfactant), and effect of small regularization--such as surface tension--on mathematically ill-posed interfacial flow problems. His studies in materials science primarily involve crystal growth and diffusion controlled moving boundary problems. In physiology, he has studied optimal suturing patterns for skin wounds and formulated models for determining the stress and strain distribution in the heart wall that occur due to changes in heart geometry.
