Although Random Matrix Theory has been developed for almost a century, its application in finance is underutilized. A random matrix is a Hermitian matrix with its entries drawn from a normal distribution with mean zero and variance one. Most of its interesting properties lie in the distribution of its eigenvalues. Not until recently has RMT been employed to estimate the profits and risks of financial portfolios. My project focuses on exploring new ways to manipulate current methods frequently adopted to maximize the profit of a financial portfolio given a certain […]

My current project is about reading performance across different methods of text presentation. The standard form of text presentation is by printed words on a page or screen in blocks of sentences and paragraphs. This way of text presentation is difficult for people who have diseases of the eye that hinder eye movement. One way to correct this problem is through rapid serial visual presentation, or RSVP, where text is presented one word at a time in sequence on a monitor. Do reading speed and comprehension improve when this method […]

Dark photon is a hypothesized gauge boson which behaves like a standard photon. It is called dark because it interacts very weakly with normal particles like electrons and protons, but instead interacts more strongly with dark matter. This makes dark photons escape previous detections easily. However, some unexpected radiation from the center of our galaxy implies the existence of dark photon. Therefore, we plan to produce dark photon by annihilation of a pair of particle and anti-particle with enough center-of-mass energy. We can look at the decay products of the […]

Discovered in 2004, graphene is a single atom thick sheet of carbon arranged in a hexagonal lattice. It is also the most conductive material at room temperature known to humankind and many believe it could replace silicon and change the future of computers and other electrical devices. Despite this, there is a long way to go before reaping the benefits of its potential applications. Because graphene is a relatively new material, scientists and engineers are still in the process of learning about its production, properties, and capabilities. For my summer […]

Salmonella enterica is a bacterium that causes major food borne disease in the world. It infects people by inducing the uptake of the bacteria by secreting proteins into cells in the host’s intestines. A crucial system of Salmonella enterica pathogenesis is the Type III Secretion System (T3SS) which transports bacterial proteins into host cells. Previous experiments indicate that the Disulfide Bond Formation (Dsb) System is needed for the Type III Secretion System. However, a direct interaction between the two systems is not currently known. Through molecular cloning and a bacterial […]

Coast Redwoods can grow over three hundred and fifty feet tall—well overtopping Sather Tower’s three hundred and seven. An individual Redwood might live in multiple above-ground micro-climates that can be especially noticeable on a sunny day: from low, perhaps shady to dry, hot, dizzyingly high-up. Macro-morphological features of their leaves (e.g. surface area and connection to the stem) have been demonstrated to correlate with such great height, suggesting that variable leaf structures work together with towering stature. What the stomata, pores, are up to meanwhile has yet to be as […]

Degradation reactions of alkyl radicals are of interest in combustion chemistry, planetary atmospheres, and the interstellar medium. However, the nature of their reaction pathways is not easily understood as the intermediates are highly reactive. My project will investigate the dissociation dynamics of a simple primary alkyl radical, 1-propyl, upon excitation at 248 nm using a detection scheme known as photofragment translational spectroscopy. Four distinctive product channels are assessed at this wavelength. A preliminary experimental work seems to indicate that the C-C bond cleavage is energetically the most favorable product channel.

This project is investigating conflicts in the representation of plant assemblages in the middle Pennsylvanian (Moscovian, 311.7 1.1 to 306.5 1.0 Mya) fossil record. Currently, the held belief is that the tropical lowlands of the Moscovian were dominated by swamp forests (coal forests) during periods of deglaciation. However, recent studies of the Baker Coal from the Cottage Grove mine of southeast Illinois show xerophytic (dry) plants sandwiched in-between layers dominated by the more common coal forest plants. This discovery infers that these floras may have been growing in close proximity […]

Laser light has been proven to be an effective and elegant method of probing sensitive physical systems, providing many seminal, precision methods in experimental physics. These experiments must prove free of systematic errors and be minimally perturbative to the phenomena to be examined. Along these lines, I am researching the properties of zero-birefringent acrylic polymers in a range of temperatures from room temperature down to a couple Kelvin. In exhibiting this unique property of zero-birefringence, these materials do not affect the polarization of light passing through them, even when under […]

The Eastern Arc Mountains of Africa have been identified as an area of high bird diversity and endemism. The forests on these mountains underwent a contraction creating sky islands. Diversity of the forest habitat suggests that the Eastern Arc Mountains served as a refuge during the Pliocene climate cycling. Current molecular technology has allowed for discovery of cryptic taxa between the sky islands. Insights in the genetic structure of populations lead to further understanding of the driving forces of evolution for endemic taxa. There is a high likelihood that similar […]
