The Rycroft Group works on a wide range of topics. A hallmark of the group's
approach is to develop new computational methods while working directly with
domain scientists. Three particular focus areas are listed below.
Many scientific fields are increasingly awash in data. We
develop new computational approaches for processing data and extracting
scientific insight, particularly those that combine
traditional analysis and modeling with new machine learning methods. For example, we have a sequence of papers on the
physics of crumpling, covering experimental observations,
new machine learning approaches, and analysis and modeling.
Geometry problems appear across many scales, from the arrangements
of atoms to the structure of galaxies, and techniques for geometric analysis
enter into many group projects. Chris Rycroft developed
Voro++, a software
library for calculating the Voronoi tessellation. The library is widely used,
and the Rycroft Group has used it for problems as diverse
as modeling insect wing patterning
and finding materials for carbon dioxide capture.
The Rycroft Group currently consists of eleven graduate students, along with
postdocs, undergraduates, and sabbatical visitors. Members have a diverse
range of backgrounds and have education in applied mathematics, physics,
engineering, and computer science. We also like obsessive color coordination!
We also support teaching a wide range of courses in the Harvard Applied
Mathematics program and in the Harvard
IACS master's program. In particular, since 2014 Chris Rycroft has taught
and developed Applied
Math 205 and Applied
Math 225, a year-long graduate course sequence in scientific computing.
