Ice sheet modeling, Daniel Martin, Lawrence Berkeley National Laboratory

Abstract:

Modeling the dynamics of ice sheets like those found in Antarctica and Greenland has become an exciting research topic. Once thought to be stable and uninteresting on human timescales, the response of the Earth’s ice sheets to recent climate change and their potential impact on global sea levels has produced a great deal of research energy devoted to understanding ice sheet dynamics, which has also produced a rich vein of mathematical research.

What are the relevant conference themes?

  • Applications in science, engineering, and industry
  • High-order methods, novel discretizations, and scalable solvers
  • High-performance computing, emerging architectures and programming paradigms
  • Inverse problems, optimization, and uncertainty quantification
  • Multiscale, multiphysics, and multilevel methods

Short Biography:

Dan Martin is a computational scientist and group leader for the Applied Numerical Algorithms Group at Lawrence Berkeley National Laboratory. His research involves development of algorithms and software for solving systems of PDEs using adaptive mesh refinement (AMR) finite volume schemes, high (4th)-order finite volume schemes for conservation laws on mapped meshes, and Chombo development and support.

Current applications of interest are developing the BISICLES AMR ice sheet model as a part of the SCIDAC-funded ProSPect application partnership, and some development work related to the COGENT gyrokinetic modeling code, which is being developed in partnership with Lawrence Livermore National Laboratory as a part of the Edge Simulation Laboratory (ESL) collaboration. Dan joined ANAG and LBL as a post-doc in 1998. He has published in a broad range of application areas including projection methods for incompressible flow, adaptive methods for MHD, phase-field dynamics in materials, and Ice sheet modeling.

Motivation:

I remember attending my first conferences as a graduate student and being completely overwhelmed, and I had support from my advisor and other students! For students from non-traditional backgrounds without those strong support structures, conferences can be even more intimidating. I think the GAG’s are a great way to help guide people through their first conference and help them understand how these things work. I am always looking for ways that I can help others along what has been an amazing path for me.
