Current Research
- In collaboration with Jamie Sethian, I have been working with Bay Area Physical Sciences Oncology Center, and computational cell modeling.
- With Jon Wilkening I have developed a code to search for three-dimensional time-periodic surface wave solutions in an inviscid fluid. The project has involved building a custom parallel multigrid solver, and employing a trust region optimization algorithm to progressively refine the solutions.
- Previously, I have worked with Arshad Kudrolli and Ashish Orpe at Clark University on a quantitative comparison of three-dimensional DEM simulations, to experimental results of flowing glass beads in an index-matched fluid. We aim to extend this work to take advantage of new X-ray imaging techniques to analyze three-dimensional dry granular packings.
- I have written an open source software library called Voro++ for carrying out 3D cell-based Voronoi tessellations. This is in use by a variety of research groups worldwide. At LBL, I am working with Maciej Haranczyk and Thomas Willems on using the library to screen databases of zeolite structures to analyze their porosity properties.
- I work with Jim Langer at UC Santa Barbara and Eran Bouchbinder at the Weizmann Institute on developing computational methods for simulating deformation in bulk metallic glasses.
- I work with the Laboratory for Thermal-Hydraulics at the Paul Scherrer Institute in Switzerland, carrying out simulations to guide the development of a scaled down experimental facility to study the effect of graphite wear in pebble-bed nuclear reactors.
- I work with with Frederic Gibou and Maxime Theillard in the Mechanical Engineering department at UC Santa Barbara on developing multigrid methods on adaptive grids.
Brief articles about previous work
Several brief articles are available about the research I carried out during my PhD on granular materials. I also have several articles highlighting some specific results and moveis from my collaborations. Further details can be found in my publications.
