A microscopic, transcriptomic, and phylogenetic investigation of the contractile vacuole of Reclinomonas americana (Jakobida, Discoba)
DownloadSpring 2023
The origin and timing of characteristic eukaryotic organelles is one of the key questions in the evolution of life on Earth. For the most part, widespread eukaryotic organelles (e.g., Golgi, mitochondria) have been inferred to be present in the last eukaryotic common ancestor (LECA) by examining...

Deciphering Petrogenetic Histories of Polymict Regolith Breccias from the Moon, Mars, and 4 Vesta
DownloadFall 2024
The geological histories of planetary bodies in our solar system can be understood by unraveling the petrogenetic histories and evolution of regolith breccias derived from their planetary surfaces. This study investigates three meteoritic breccias, Northwest Africa (NWA) 14340, Sariçiçek, and NWA...

Affinity maturation is the process to improve antibody affinity for an antigen during an adaptive immune response; it is mediated by the immunoglobulin mutator enzyme activation-induced cytidine deaminase (AID). This process is crucial to produce high-affinity memory B-cells and plasma cells. In...

Vertebrate vision is mediated through the absorption of light by the rod and the cone photoreceptors. Early jawed vertebrates initially had four cone subtypes, which sampled different regions of the visual spectrum to allow colour vision, and a single rod type which enabled vision in dim light....

Investigating the Role of Paralogous Gene Expansion and Functional Homology of Membrane-Trafficking Machinery in Organellogenesis: Apicomplexan Parasites as a Model Case
DownloadFall 2019
The ease with which large multicellular organisms, such as plants and animals, may be observed belies an unappreciated wealth of diversity; the majority of eukaryotes are unicellular, and display a dazzling array of morphologies and lifestyles. Some eukaryotes are free-living or symbiotic,...

Systematics of Clupeomorpha (Osteichthyes:Teleostei) with methodological considerations for morphological phylogenetics
DownloadFall 2020
Here I conduct a systematic revision of Clupeomorpha, a group of bony fishes that includes over 500 living and extinct species of herrings, sardines, anchovies, and their relatives. Despite a long history of research on clupeomorph fishes, evolutionary relationships within the group remain poorly...

Fall 2024
The taxonomic rank of species remains a fundamental unit in the study of biodiversity. However, speciation processes are diverse, making it challenging to delimit species. This difficulty is conflated by methodological issues including the use of too few characters, low sample sizes, and prior...
