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 […]

From Homers Odyssey to Dostoevskys Crime and Punishment, the average American high school graduate has at least encountered a work of foreign literature in translation. Yet those students have not likely read the same translations of the works. Where the original language text is fixed, translations can differ wildly. Whats more, there are both British and American versions of Harry Potter; because of cultural differences from one English speaking country to another, there are translations of a book from one language to the same language. How much then, does culture […]

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 […]

Dopaminergic projections from the midbrain to the striatum and prefrontal cortex are known to affect widespread brain processes, including reward, movement, cognitive control and working memory. Lower dopamine levels in the striatum are linked with higher body mass index, poorer decision making in relation to food choice and a skewed sense of healthiness of food items. I propose to investigate the role of dopamine in a working memory task and decision making on the food task and examine if a relationship exists between the two tasks. I will also investigate […]

In Classical Athens, many children died before adulthood. For a culture that practiced the exposure, or infanticide, of unwanted newborns, the value of the sub-adult life has been difficult to define. What did a child mean to the Athenian family and state? Once a child had been chosen to rear, its life must have been quite valuable, since the family spent lavish sums on the erection of grave markers for deceased children. These gravestones, carved in relief with images of children, provide iconographic information that may help to fill in […]

The disparity in earnings between students with and without a college degree has been growing for the past twenty-five years, and has become pivotal in determining the future stability of the nations youth. Through this research project, I will explore the college predispositions of low-income students of color recently accepted in College Track, an after school college preparatory program in Oakland. By focusing on three elements of the program: the college-focused activities, the extracurricular/supplemental opportunities, and the staff, I aim to understand the motivations that lead rising 9th graders to […]

Arboreal animals such as the Green Anole, Anolis carolinensis, must be able to manipulate aerial descent to reduce injury when dislodged from elevated habitats. To maintain controlled aerial descent, the anole must obtain a prone posture. Anoles have been known to correct orientation after dislodgement by use of their tails through either the conservation of momentum to induce roll or by lateral swings which alter yaw. While the mechanics behind yaw and roll alterations are understood, the extent to which an anole can correct pitch at high angles is not. […]

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 […]
