The Large Underground Xenon, or LUX, collaboration has spent the last few years constructing a dual-phase liquid xenon detector which is sensitive enough to detect weakly interacting massive particles (WIMPs), the primary candidate for dark matter. The detector is finally running and has been taking data since February of this year. With the first round of data in hand, I will analyze LUXs current level of performance. I will look for unexpected drops in its photo-detection rates and other signs that previously unaccounted for factors are limiting the detectors efficiency. The ultimate goal is to determine whether the detector is running as well as it needs to before the second round of data is taken. If it isnt, I will make recommendations for methods of measuring and investigating the factors I have studied.

Dark matter is ubiquitous in this universe yet has not been detected directly. The leading candidate particles for dark matter are Weakly Interacting Massive Particles (WIMPs). The Cryogenic Dark Matter Search utilizes measurement of ionization and phonons in order to discriminate between background particles and rare WIMP interactions. Achieving complete charge collection by the ionization readout is challenging due to trapping within the low temperature Germanium detectors. The charge transport experiment will provide great insight into the phenomenon of charge trapping and this information will have wide implications in low temperature semiconductor physics. Examining the trapping curves will also allow us to better understand the charge collection mechanism for the CDMS detectors. With this information we can more accurately distinguish between background particles and rare WIMP interactions, eventually leading to the detection of dark matter.

I will be working with the Murine gammaherpesvirus 68 (MHV68), a member of the Herpesviridae family consisting of over one hundred viruses capable of infecting a wide array of hosts. My gene of interest, muSOX, is a viral gene that targets and cleaves cytoplasmic host mRNAs and is the mouse analog of the SOX gene in the human gammaherpesvirus. A former graduate student constructed an MHV68 virus that is defective for host shutoff (HS). The HS virus has a single point mutation R443I and is incapable of targeting and degrading host cytoplasmic mRNAs. This summer, my job will be to confirm that phenotypes observed in the HS virus are due to only absence of host shutoff activity and not an unintended consequence of the R443I mutation. To do this, I will be creating another MHV68 virus that is defective for host shutoff and contains a different point mutation, L132F.

Type Ia supernovae are the thermonuclear explosions of critical mass white dwarves which have reached the Chandrasekar mass through accretion of mass from their binary companion. The near constancy of their maximum intrinsic brightness is the key to the use of these events in cosmological studies. Unfortunately, systematic errors associated with the diversity of type Ia supernovae continue to limit their usefulness as standard candles. I will use a very large spectroscopic and photometric data set gathered by the Palomar Transient Factory (PTF) in order to identify correlations between the stretch parameter of type Ia light curves and a variety of parameters derived from type Ia blackbody spectra. Combining the correlations between photometric and spectroscopic parameters I hope to obtain a new correction to type Ia maximum intrinsic luminosity. Furthermore, I would like to apply this new correction to obtain a new value for Hubbles constant using the PTF data.

The objective of this work is to study electric field noise from metallic surfaces at low frequencies observed in ultra-low temperature ion traps. This source of noise has been a major issue for ion trapping experiments because it heats up the cold ions several orders of magnitude faster than what was expected. This heating is a serious problem and hinders progress in the use of ions, as dependably controllable qubits, toward a scalable quantum computer. The expected benefits from this research is the determination of the frequency scaling of this anomalous heating, which will shed light on the origin of this noise and, in turn, on ways to mitigate it.

The Chinese Exclusion Act is considered the most racist law in U.S. history; it entailed quarantining immigrants for up to two years on Angel Island, resulting in a collection of poetry carved by the detainees onto the walls of the detention barracks. Given the tumultuous history of immigration from south of the border, where is this poetry for Mexican and Central American immigrants? While immigration has been extensively studied through various academic perspectives, the literature from the immigrants themselves has largely remained untouched. By identifying the trajectory of literature by undocumented immigrants, I will analyze how policy may have driven the changes in language and style of this corpus of literature and, conversely, what the literature reveals about policy itself. In creating an aesthetic for The Literature of the Undocumented, I will argue for its differentiation from Chicano Literature, under which the literature is currently (mis)categorized.

Wildfires annually burn hundreds of thousands of acres of the Western United States, forcing mass evacuations, burning residences and costing hundreds of millions of dollars. Using a Geographic Information System (GIS), my project aims to model the wildfire potential of the Angeles National Forest, a large and diverse natural area just outside the city of Los Angeles. Considering variables such as fuel type and moisture content, temperature, precipitation, slope, and winds, I will determine the areas of the forest most conducive to a destructive fire. Using these ‘hot spots,’ I will analyze the resource allocation of the fire fighting units surrounding the forest. By the end of my project, I intend to have developed a model capable of incorporating future climate scenarios and being applied to other areas of the state.

Many communities in the San Francisco Bay Area struggle with food insecurity or the lack of access to healthy and affordable food, making them more likely to suffer from diet-related diseases such as obesity and diabetes. Because these communities have a base of corner stores where people already shop, such as liquor stores or other smaller-scale stores, bringing healthy options to local corner stores may be a more effective strategy than developing larger supermarkets. My project will examine whether the federal governments strategies of providing financial incentives to storeowners is an effective way of increasing the availability of healthy food. I will also learn how local and state governments can make the process of corner-store conversion not only more appealing but easier and less demanding for storeowners. My research will involve looking at government policies as well as interviewing storeowners and other key players in the healthy corner store movement.

I am currently exploring the question of the ways in which the phrase as if — as it appears in novels by Henry James, particularly What Maisie Knew — implicates integration into a social existence in which the curious and problematic acceptance of both reality and unreality is required of the self, particularly the pre-adolescent self. This is a vital question because, first, it offers a foundation from which to examine the complex interplay between several important novelistic factors: the self in relation to the other, the socialization of the child, the divide between the conscious and unconscious mind, and the necessary falsehoods perpetuated by social existence (to name a few). Second, the words as if and the work these words do within the novel as a literary genre is a topic which has received little attention and, yet, is of paramount importance in regard to both novelistic form and […]

The Extraordinary Chambers in the Courts of Cambodia (ECCC) was established in 2003 with the goal of trying those responsible for the horrors inflicted upon Cambodia under the Khmer Rouge between 1975-1979. Two of the original four Accused in Case 002 are currently being tried at this Khmer Rouge Tribunal, and as part of my research, I will be monitoring these trials at the ECCC on the outskirts of Phnom Penh. By observing these trials and interviewing experts on the ECCC and the Democratic Kampuchea period, I intend to examine the influence of the tribunal and other sites of historical importance, such as the Killing Fields and the Tuol Sleng Genocide Museum, on the development of a national collective memory of the Khmer Rouge era. Public consciousness is undoubtedly being molded by these trials and memorials, and my project will provide insight into how this history is being developed and […]
