Nearly all life on Earth depends on oxygenic photosynthesis, the process by which light energy is used to create sugars and oxygen from water and carbon dioxide. In plants and algae, it is carried out in organelles called chloroplasts, which are cousins of photosynthetic bacteria known as cyanobacteria. Both chloroplasts and cyanobacteria contain membrane-enclosed sacs called thylakoids, and the light-dependent reactions of photosynthesis take place in the thylakoid membrane. Here, light hits the protein complex Photosystem II (PSII), and this energy is used to split water into oxygen, protons, and […]

The way that brain cells wire together to form circuits underlies almost every facet of mental function, whether that be memory, thinking, or sensation. In my project, I seek to better understand what happens on a molecular level that allows for these specific circuits to form. Specifically, I want to elucidate the role that the maturation of synapsesthe connections between neuronshas on the shape, structure, and connectivity of the neurons making up these circuits, and how experience drives these changes. I will do this using the zebrafish visual processing system, […]

“Dengue is a mosquito-borne viral disease that places about three billion people at risk for infection yearly in tropical and sub-tropical regions worldwide. Infected individuals can be asymptomatic, or they can show clinical disease, including an acute debilitating fever (Dengue Fever) that can progress to life-threatening conditions of severe dengue, including Dengue Shock Syndrome (DSS). The goal of this research is to investigate whether cell-free nucleic acids in patient serum can serve as biomarkers to distinguish between cases of mild and severe dengue disease. I will accomplish this by characterizing […]

Learning a motor skill takes a use of error-based learning to devise new strategies towards mastering that skill. Motor skills are perfected through attempting new solutions based on previous movement errors. The presence of motor noise, which is variability between repetitions of the same motor movement, can interfere with error learning as the previous movement error could be from incorrect planning or baseline motor noise. Past research on motor learning has found that while under certain conditions high motor noise is beneficial in learning during a motor task, it is […]

An algebraic variety is a generalization of a solution set to a family of polynomial equations. De Concini and Procesi developed a canonical method of compactifying any symmetric variety. This resulting compactification, called the wonderful compactification, has many favorable algebraic and geometric properties. Alexeev and Brion developed a method of degenerating any spherical variety to a toric variety. Many tools, such as combinatorics, can be used to study toric varieties in great detail. Thus, my main goal is to develop and study toric degenerations of the wonderful compactification. Eventually, I […]

Squeezed light is a quantum mechanical state of light with smaller uncertainty in a component of interest (i.e., amplitude or phase) than what is observed in classical light. This reduced uncertainty is equivalent to reducing noise in the component of interest, which thereby allows ultraprecision measurements. Parametric Amplifiers are devices that can generate squeezed light. Experiments have shown that these devices have some non-ideal behaviour, but there is insufficient data to rigorously characterize these non-idealities. This project aims at developing efficient and fast methods to quantitatively measure the squeezed microwaves […]
