Research Interests
- Fault-Tolerance in HPC-algorithms: scalable restoration of data
- Phylogenetic tree inference
- Fault-tolerant basic toolbox algorithms (MapReduce, …)
- Checkpointless fault-tolerance and lossy checkpoint compression
- Judicious hypergraph partitioning
Software
- Fault-Tolerant RAxML-NG (FT-RAxML-NG) Fault-tolerant version of the popular RAxML-NG phylogenetic inference tool
- ReStore (in-memory REplicated STORagE for rapid recovery in fault-tolerant algorithms)
- Coraxlib (COre RAXml LIBrary) encapsulates common routines used by likelihood-based phylogenetic software
