The Marschall Lab
Our research group, headed by Prof. Dr. Tobias Marschall, mainly works on genome data science,
with a focus on novel algorithms and software tools for computational genomics.
We address computational challenges arising from latest sequencing technologies to further our understanding
of genomic variation and their consequences on phenotypic variation and disease.
Over the past years, a special emphasis has been on methods for haplotype reconstruction,
genome assembly, structural variation analysis, pangenomics and single-cell genomics.
New publication: Constructing founder sets under allelic and non-allelic homologous recombination
October 2, 2023
We present a simple but powerful computational model of homologous allelic and
non-allelic recombination which leverages pangenome graphs, capable of
representing large structural variants including duplications, deletions and
inversions. We formulated and provided solutions for two founder set problems
under it and described exact methods for characterizing the number of
recombinations.

Our new group website is online! Thanks to free software and the work of Adam Phillippy’s lab, the “perfect wheel” already existed and we did not have to reinvent anything!
