A Comprehensive Metagenomic Study of the Antarctic Untersee Oasis as an Astrobiological Analog
(Georgetown University, 2022)Astrobiology is the study of the “living universe,” which includes the study of the origin of lifeas well as its evolution and distribution on Earth and beyond. Prime candidates for alien life include the icy moons of the ... -
Age Determination, Life History and Juvenile Behavior in Bottlenose Dolphins (Tursiops sp.) in Shark Bay, Australia
(Georgetown University, 2013)Although of theoretical interest, the juvenile period in mammals is a relatively neglected area of research. In large-brained and social mammals, such as bottlenose dolphins, where juvenile periods are prolonged, life ... -
Assessing the Function of SOX21 in Xenopus laevis Neurogenesis: Exploring Homeolog Sub-Functionalization
(Georgetown University, 2021)Neurogenesis is a tightly controlled developmental process through which neural progenitor cells progress to committed neurons. While the SoxB1 transcription factors are well characterized to have functions in the induction ... -
Assessing the Function of SOX21 in Xenopus laevis Neurogenesis: Exploring Homeolog Sub-Functionalization
(Georgetown University, 2021)Neurogenesis is a tightly controlled developmental process through which neural progenitor cells progress to committed neurons. While the SoxB1 transcription factors are well characterized to have functions in the induction ... -
Behavioral ecology of wasp-spider interactions : the role of webs, chemicals, and deception
(Georgetown University, 2010) -
Characterization of Sox11 in Neurogenesis
(Georgetown University, 2016)CHARACTERIZATION OF SOX11 IN NEUROGENESIS -
Characterization of the Function of Sox21 During Neurogenesis
(Georgetown University, 2014)Neurogenesis, the progression from neural progenitor to committed neuron, is a tightly regulated process that is fundamental for development of the central nervous system. Whereas the SoxB1 transcriptional activators are ... -
Computational Analysis of Difficult-to-predict Genes and Detection of Lineage-specific Genes in Honey Bee (Apis mellifera)
(Georgetown University, 2013)Honey bees are key agricultural pollinators and a research model for social behavior and the evolution of eusociality. Generation of reliable gene predictions is critical to the success of laboratory experiments and ... -
Computational and Functional Analysis of F-box Dependent Ubiquitin Ligases in Xenopus Nervous System Development
(Georgetown University, 2013)The development of the central nervous system is a dynamic process during which protein levels are regulated temporally and spatially by synthesis and degradation. While much is known about the regulation of gene expression ... -
Conserved Genetic Mechanisms for Deuterostome Gut Regionalization
(Georgetown University, 2013)The vertebrate digestive system is comprised of several discrete organs of varied function arranged in a stereotyped pattern along the anterior/posterior (A/P) axis. A tightly regulated transcriptional network regionalizes ... -
Ecological and Life History Factors Influence Habitat and Tool Use in Wild Bottlenose Dolphins (Tursiops sp.)
(Georgetown University, 2012)While it has long been known that individual animals behave quite distinctively from other conspecifics, only recently has this intraspecific behavioral variation itself been the subject of investigation rather than a ... -
Ecology and population differentiation of the Asian tiger mosquito, Aedes albopictus
(Georgetown University, 2009) -
Effects of Senescence on Reproduction and Behavior in Bottlenose Dolphins
(Georgetown University, 2019)Senescence is the degenerative change in function of all organ systems with age and is accompanied by precipitous declines in survival and fertility. In a few species, reproductive senescence culminates in menopause, the ... -
Exploring Variation in Learning Ability in Pieris rapae, the Cabbage White Butterfly
(Georgetown University, 2013)Learning abilities allow animals to modify their behaviors based on experience; such plasticity provides an adaptive mechanism for responding to environmental unpredictability. As with any heritable trait subject to natural ... -
FITNESS, POLLEN DISPERSAL, AND FLORAL-DISPLAY SIZE EVOLUTION IN ANIMAL-POLLINATED PLANTS
(Georgetown University, 2011)The great variation in floral-display size (the number of flowers per plant) (FDS) in the thousands of angiosperm species has intrigued biologists and others for centuries, eliciting investigations regarding the ecology, ... -
Function of Oct91 and SoxB1 proteins during neural development in Xenopus laevis
(Georgetown University, 2009) -
Giardia lamblia, the Intestinal Microbiome, and Innate Immunity: A Study of the Host-Parasite Relationship during G. lamblia Infection
(Georgetown University, 2015)Infection with the protozoan parasite G. lamblia is a major cause of diarrheal disease worldwide. Prevalence is highest in developing countries with an estimated 20-30% of the population infected at any given time. G. ... -
The GLI transcription factors as a therapeutic target in childhood cancers
(Georgetown University, 2010) -
Grf10 Transcription Factor Coordinates Nutrient Assimilation, Metabolism and Morphogenesis in Candida albicans
(Georgetown University, 2018)Candida albicans is a commensal of the human microbiome and a major human fungal pathogen. Morphogenesis and metabolism are key attributes that allow C. albicans to thrive and infect the human host. Grf10, a homeodomain-containing ... -
HIV TAT Induced Gliosis and Changes in Perineuronal Nets and Parvalbumin Positive Interneurons
(Georgetown University, 2022)HIV (human immunodeficiency virus) is a retrovirus affecting approximately 1.2 million people in the United States according to the CDC. This virus causes severe damage to the immune system eventually leading to acquired ...
