 Daniel Appelo, Associate Professor

The Appelö High Order Group focuses on the development of novel high order accurate discretization of partial differential equations modeling problems form science and engineering. Daniel's primary research interest is the development, analysis and implementation of fast, stable and accurate numerical algorithms for approximation of partial differential equations arising in engineering and natural sciences. Another research topic Daniel has focused on is the development of artificial boundary conditions that are required to solve time dependent partial differential equations on unbounded domains.

 Keith Julien, Professor
 Professor Julien’s primary area of research is focussed in the mathematical geo and astrophysical sciences. Specifically, the modeling of dynamical processes, instabilities and turbulence occurring within the extreme parameter regimes typical of geophysical and astrophysical flows. Utilizing multiscale asymptotics, particular emphasis is placed on the identification of reduced PDE models that both accurately captures limiting solutions and describe key phenomena such as coherent structures, the transport and organization of largescale flows, mean flow generation, and wave propagation Example areas include protoplanetary disks, stably and unstably stratified flows (such as penetrative convection, rotating and magneto convection), shear flows and boundary effects in turbulent convection. Complimentary to these interest is the development of fast numerical algorithms for the purpose of numerical simulations on state of the art high performance computing architectures.
