Biography
Anshu Dubey is a Senior Computational Scientist with extensive experience in design, architecture and sustainability of multiphysics scientific software used on high performance computing platforms. Her contributions in the area of software engineering for research scientific software are widely known and respected. She has been the chief software architect for FLASH, a multiphysics multicomponent software that is used by several science domains including astrophysics, cosmology, solar physics, bio-mechanical systems, computational fluid dynamics and laser plasma experiments. She continues to lead the development of Flash-X, a new version of the code designed for heterogeneous architectures. She serves on scientific advisory of the National High-Performance Computing Alliance, Germany. She has also served as the lead for Earth and Space Science Applications in the Exascale Computing Project.
Anshu Dubey received her B. Tech from Indian Institute of Technology, New Delhi in 1985, Masters from Auburn University in 1990, and Ph.D. in computer science from Old Dominion University in 1993. She then joined the University of Chicago Astronomy & Astrophysics Department as a research associate and was promoted to research scientist in 1998. In 2001 she joined the ASC/Flash Center as lead application programmer, where she became computer science/applications group leader in 2003, and associate director in 2010. From 2013 to 2015 she was on the staff at Lawrence Berkeley National Laboratory, where she served as work lead and computer systems engineer in the Applied Numerical Algorithms Group. In 2015 she joined the Mathematics and Computer Science Division at Argonne as a computational scientist. She is also a Senior Scientist in the Computer Science Department at the University of Chicago.
