This paper presents the state of the art in the area of topology‐based visualization. It
describes the process and results of an extensive annotation for generating a definition and …

Data reduction is increasingly being applied to scientific data for numerical simulations,
scientific visualizations and data analyses. It is most often used to lower I/O and storage …

In January 2019, the US Department of Energy, Office of Science program in Advanced
Scientific Computing Research, convened a workshop to identify priority research directions …

This paper presents a new algorithm for the fast, shared memory multi-core computation of
augmented merge trees on triangulations. In contrast to most existing parallel algorithms …

This paper presents a new algorithm for the fast, shared memory multi-threaded computation
of contour trees on tetrahedral meshes. In contrast to previous multi-threaded algorithms, our …

This paper presents a robust and efficient method for tracking topological features in time-
varying scalar data. Structures are tracked based on the optimal matching between …

This book is adapted from my habilitation thesis manuscript, which reviewed my research
work since my Ph. D. thesis defense (2008), as a postdoctoral researcher at the University of …

A data-driven approach to classify combustion regimes in detonation waves is implemented,
and a procedure for domain-localized source term modeling based on these classifications …

With the continuous rise in complexity of modern supercomputers, optimizing the
performance of large-scale parallel programs is becoming increasingly challenging …
