# CRD Researchers to Present 18 Posters at ASCR Applied Math PI Meeting

September 11, 2017

Principal investigators for applied math projects are meeting this week in the Washington, D.C. to share research results and hold focused discussions on research areas. In all, researchers from Berkeley Lab will present 18 posters at the Sept. 11-12 2017 ASCR Applied Mathematics Principal Investigators Meeting.

Eight of the posters will be by presented by members of the Center for Computational Sciences and Engineering (CCSE), six by members of Mathematics Group/CAMERA, the Center for Advanced Mathematics for Energy Research Applications, two by staff from the Performance and Algorithms Research Group (PAR) and one by the Applied Numerical Algorithms Group (ANAG). Here’s the list:

- Ann Almgren, CCSE, “A Hybrid Adaptive Low‐Mach‐Number / Compressible Method for Solving the Navier‐Stokes Equations,”
- Ariful Azad, PAR, “Productive and extreme‐scale graph computation enabled by GraphBLAS,"
