THE LEMON TREE: MY TREE OF LIFE
<p><em>The Lemon Tree</em> is a collection of poems that arose from my attempt to capture memories of influential experiences in growing up. The poems are written in prose blocks and move in and out of childlike and adult sensibilities, creating the disillusion of time and memory. The poems …

Germline and somatic mutational processes across the Tree of Life
… sequence both the forward and reverse strands of a circular DNA template. By leveraging the redundancy of multiple passes and the complementarity of the strands, a consensus algorithm generates a highly accurate CCS read, achieving a minimum read accuracy of Q20. In this PhD thesis, I …

Uncovering Molecular Mechanisms Regulating Circadian Amplitude Across the Tree of Life
… formed by genes termed core clock genes. Some of these clock genes function as transcription factors to control the timely expression of each other as well as thousands of downstream clock-controlled genes. The amplitude of circadian rhythms, or the daily variation of a rhythm's peak to the …

Confronting the Tree of Life: Three Court Cases in Modern American History
Like few other concepts in the history of science, Darwinian evolution prompted humans to question their most basic assumptions about themselves. Among the theory's most controversial implications, the principle of common descent insisted that humans were kin to other species. As such, common …

Hierarchy Aligned Commonality Through Prototypical Networks: Discovering Evolutionary Traits over Tree-of-Life
… discover evolutionary traits, which are features of organisms common to a group of species with a shared ancestor in the Tree of Life (also referred to as phylogenetic tree). With the recent availability of large-scale image repositories in biology and advances in the field of explainable machine …

Major transitions in the plant tree of life: insights from genes, genomes and traits
The evolution of plants transformed the Earth’s surface, atmosphere and climate and enabled the colonisation of new habitats, promoting the diversity of other lineages spanning the tree of life. The evolutionary history of plants has been marked by major transitions such as multicellularity, …

Probing statistical patterns across the tree of life: Comparative methods for microbial genomes and traits
… published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2025-12-01

Novel approaches for large-scale phylogenetics and applications in the context of the amphibian tree of life
… missing data and careful handling and addition of novel data in large-scale reconstructions, presenting an application of this approach in the context of amphibian phylogenetics. I developed a method (called “Concatabominations”) building on the original Safe Taxonomic Reduction method …

Eden in the Book of Revelation
The book of Revelation engages the Genesis story of Eden at several points. In Revelation you find the tree of life, the serpent, and many other images from the Eden narrative. This exploratory thesis analyzes the potential uses of the Eden narrative in John's Apocalypse. This project examines Rev …

Jumpstarting Phylogenetic Searches
… analysis is a central tool in studies of comparative genomics. When a new region of DNA is isolated and sequenced, researchers are often forced to throw away months of computation on an existing phylogeny of homologous sequences in order to incorporate this new sequence. The previously …

Novel computational methods for discordance-aware phylogenomic analysis
Inferring the evolutionary history of a set of species is a key step in many biological and medical research projects, as species trees provide a context in which problems in comparative genomics, biodiversity, phylogeography and epidemiology can be addressed. Recent advances in sequencing …

Evolution of the Tree Symbol as a Metaphor for Individualization
<p>This thesis addresses the tree symbol as it relates to the process of human individuation. The tree symbol is shown to be a metaphor for psychological development from ancient times to the present day. The evolution of this metaphor of the tree is explored. The specific uses of the tree as …

Low complexity regions in Biological Matter: Sequences, higher-order assembly, and evolution.
From the fibrous silk of a spider to liquid-like nucleoli, biological matter plays important roles in organisms. How does biological matter assemble from component parts, carry out important organismal functions, and evolve in the tree of life? Low complexity regions (LCRs) of proteins are simple …

Phylogenomic analysis of hemimetabolan insects with emphasis on the hemipteran suborder Auchenorrhyncha and the superorder Paraneoptera
Insects are the among the most diverse groups of organisms on the planet and understanding the factors contributing to their evolution has long been a goal of systematic entomology. However, despite efforts to reconstruct their evolutionary history using morphological and molecular Sanger …

Big Data Phylogenomics: Methods and Applications
Phylogenomics, the study of genome-scale data containing many genes and species, has advanced our understanding of patterns of evolutionary relationships and processes throughout the Tree of Life. Recent research studies frequently use such large-scale datasets with the expectation of recovering …

Investigation of Specialized Metabolites in Apicomplexan Parasite Life Cycles
<p>Across the tree of life, specialized metabolites mediate ecological interactions and can ultimately drive evolution. Characterization of these small molecules have led scientists to a greater comprehension of ecological niches at the macro- and micro-scale. A group of medicinally important …

Under the hanging tree: everyday life and historical memory in Central Namibia
… in central Namibia, most prominently the hanging tree at Otjinene and the battle landscape of Okandjira, function as lieux de mémoire, shaping collective memory, identity, and claims to justice in the present. Building on Pierre Nora’s theorization of memory-sites and Martha & Bruce Lincoln’s work …

Convergent Evolution of Biochemical Innovations in Polychaetes: Characterizing the Molecular Basis of Bioluminescence and Venom Production
<p>The convergent evolution of phenotypic traits is a widespread phenomenon across the tree of life and is explained as the outcome of different taxa facing similar selective forces or environmental conditions. A longstanding question in evolutionary biology is whether the evolution of convergent …
