Published in 2018 at "American journal of botany"

DOI: 10.1002/ajb2.1069

Abstract: PREMISE OF THE STUDY The Caryophyllales contain ~12,500 species and are known for their cosmopolitan distribution, convergence of trait evolution, and extreme adaptations. Some relationships within the Caryophyllales, like those of many large plant clades,… read more here.

Published in 2021 at "Bioinformatics"

DOI: 10.1093/bioinformatics/btab328

Abstract: Abstract Motivation It is largely established that all extant mitochondria originated from a unique endosymbiotic event integrating an α−proteobacterial genome into an eukaryotic cell. Subsequently, eukaryote evolution has been marked by episodes of gene transfer,… read more here.

Published in 2022 at "Bioinformatics"

DOI: 10.1093/bioinformatics/btac265

Abstract: Abstract Motivation Phylogenomics faces a dilemma: on the one hand, most accurate species and gene tree estimation methods are those that co-estimate them; on the other hand, these co-estimation methods do not scale to moderately… read more here.

Published in 2017 at "Bioinformatics"

DOI: 10.1093/bioinformatics/btx079

Abstract: Motivation: It is well known that gene trees and species trees may have different topologies. One explanation is incomplete lineage sorting, which is commonly modeled by the coalescent process. In multispecies coalescent, a gene tree… read more here.

Published in 2020 at "Systematic biology"

DOI: 10.1093/sysbio/syaa083

Abstract: The genomic revolution offers renewed hope of resolving rapid radiations in the Tree of Life. The development of the multispecies coalescent (MSC) model and improved gene tree estimation methods can better accommodate gene tree heterogeneity… read more here.

Published in 2022 at "Systematic biology"

DOI: 10.1093/sysbio/syac055

Abstract: Gene tree discordance is expected in phylogenomic trees and biological processes are often invoked to explain it. However, heterogeneous levels of phylogenetic signal among individuals within datasets may cause artifactual sources of topological discordance. We… read more here.

Published in 2022 at "Molecular Biology and Evolution"

DOI: 10.1101/2022.02.19.481132

Abstract: Phylogenomic analyses routinely estimate species trees using methods that account for gene tree discordance. However, the most scalable species tree inference methods, which summarize independently inferred gene trees to obtain a species tree, are sensitive… read more here.

Published in 2017 at "IEEE/ACM Transactions on Computational Biology and Bioinformatics"

DOI: 10.1109/tcbb.2016.2520937

Abstract: The minimizing-deep-coalescence (MDC) approach infers a median (species) tree for a given set of gene trees under the deep coalescence cost. This cost accounts for the minimum number of deep coalescences needed to reconcile a… read more here.

Published in 2022 at "Molecular Ecology Resources"

DOI: 10.1111/1755-0998.13684

Abstract: The analysis of target enrichment data in phylogenetics lacks optimization toward using paralogues for phylogenetic reconstruction. We developed a novel approach of detecting paralogues and utilizing them for phylogenetic tree inference, by retrieving both ortho‐… read more here.

Published in 2018 at "Methods in Ecology and Evolution"

DOI: 10.1111/2041-210x.12846

Abstract: Explanations for gene tree discordance with respect to a species tree are commonly attributed to deep coalescence (also known as incomplete lineage sorting [ILS]), as well as different evolutionary processes such as hybridization, horizontal gene… read more here.

Published in 2020 at "PLoS ONE"

DOI: 10.1371/journal.pone.0232950

Abstract: Almost all standard phylogenetic methods for reconstructing gene trees result in unrooted trees; yet, many of the most useful applications of gene trees require that the gene trees be correctly rooted. As a result, several… read more here.
