Part of my postdoc has focused on adapting paralog processing methods designed for genome and transcriptome data to target enrichment data.
I used an automated, tree-based approach for paralog processing in a target enrichment data set of Alchemilla. By taking paralogs into consideration, I identified four nodes in the backbone with an elevated proportion of gene duplication and established the autopolyploidy origin of the entire Alchemilla and the nested allopolyploidy origin of four clades within the group.
Also during my postdoc, I have been focusing on exploring sources of gene tree discordance in the backbone phylogeny of the plant family Amaranthaceae s.l, using phylotranscriptomic analysis in combination with reference genomes.
I found that a combination of processes might have acted simultaneously to generate high levels of gene tree discordance in Amaranthaceae s.l. This suggests that the backbone of Amaranthaceae s.l. might be a product of ancient and rapid lineage diversification.
For my doctoral dissertation, I combined natural history collections with a plurality of phylogenetic methods to elucidate the reticulate evolutionary of the neotropical plant genus Lachemilla in the rose family.
I found widespread patterns of phylogenetic discordance as a product of ancient and recent polyploidy (autopolyploidy and allopolyploidy) as well as ancient hybridization among major clades of Lachemilla.
As an undergrad, I developed a keen interest in plant taxonomy and herbarium curation. My main taxonomic focus has been the genus Lachemilla, for which I have described six new species as part of a collaborative effort to a comprehensive monograph of the group.
I am also involved in other collaborative works to develop chloroplast and nuclear (Hyb-seq) markers for phylogenomics analyses in other plant groups like Thalictrum, Castilleja, Capriofoliaceae, and Malvaceae.
Furthermore, I collaborate in a phylotranscriptomic study focusing on the adaptation to aquatic and marine habitats in Alismatales.
