The Interplay between Human Behavior and Infectious Disease Dynamics
(Georgetown University, 2021)
Human behavior and infectious disease are related in a dynamic feedback loop. This integral and ubiquitous relationship is often ignored in epidemiological modeling, leading to findings that overlook a crucial element in ...
Pseudophosphatases Enhance Siw14, an Inositol Pyrophosphate Phosphatase that Negatively Regulates the Environmental Stress Response through Msn2
(Georgetown University, 2021)
Inositol pyrophosphates are high energy signaling molecules found across eukaryotes that are important for diverse cellular processes like phosphate homeostasis, the immune response, fungal pathogenicity, endocytosis, ...
Transcription Factors, Sigma Factors, and Regulatory RNAs Coordinate and Integrate the Staphylococcus aureus Stress Response
(Georgetown University, 2020)
Staphylococcus aureus infections impose a serious economic burden on healthcare facilities and patients because of the emergence of strains resistant to last-line antibiotics. Understanding the physiological processes ...
Purinergic Signaling Regulates the Form and Function of the Developing Cochlea
(Georgetown University, 2020)
Hearing depends on a properly formed inner ear to transmit sound information to the brain. Purinergic signaling has been implicated in the development of the inner ear, especially with regard to the cochlea. P2rx3 receptors ...
Studies on Matrix-Metalloproteinase 13 as a Novel Microglial Inflammatory Agent in Familial Synucleinopathy
(Georgetown University, 2020)
α-Synuclein is a 140-amino acid protein highly expressed in presynaptic terminals and is also associated with Lewy body pathology found in Lewy Body Dementia (LBD) and Parkinson’s disease (PD) patients. We and others have ...
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 ...
No Longer Forgotten: Pupation as a Critical Link in the Lepidopteran Life Cycle
(Georgetown University, 2021)
Holometabolous insects, those that undergo complete metamorphosis, owe their tremendous evolutionary success in large part to an efficient division of labor between a larval phase that focuses on feeding, and an adult phase ...
Lifetime Stability, Maternal Effects, and Fitness Outcomes of Socio-Ecological Strategies in Wild Bottlenose Dolphins
(Georgetown University, 2021)
Individuals within a population differ in behavior along both social and ecological axes. These differences are proposed to be governed by niche theory at the individual level, but empirical evidence is sparse, especially ...
Pou3f4-Expressing Otic Mesenchyme Cells: A Novel Influence for Cochlear Spiral Ganglion Neuron Survival
(Georgetown University, 2022)
Current therapies to improve hearing, including hearing aids and cochlear implants, require intact and functional auditory neurons. Within the inner ear, the primary auditory neurons, called spiral ganglion neurons (SGNs), ...
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 ...
