My research focuses on the growing recognition that the scientific study of consciousness is lacking in one crucial element: a rigorous methodology for examining the first-person, qualitative aspects of conscious states. While neuroimaging and computational cognition have greatly enhanced our knowledge of brain function, we are no closer to bridging the explanatory gap. That is, how does neuronal activity create the deeply complex, subjective, and personal world that each of us experiences? Though conventional scientific study does not currently recognize introspection as a valid method of inquiry, I will examine the ways in which Buddhist contemplative practices may be used to study consciousness directly, as they have been used for more than 2,000 years. I seek to define and develop a precise methodology of meditation techniques to be used in conjunction with neuroscientific studies to heighten our understanding of consciousness. I will spend my time perusing the literature on contemplative […]
To judge whether an economic bubble would lead to a financial crash and to estimate the critical time of a crash are significant in financial areas. The Log-Periodic Power Law (LPPL) is an equation that describes how bubbles evolve and grow. By fitting the equation into a financial time series, it is possible to predict the event of a crash. The equation proves to be effective in predicting several financial crises, such as the one in 2008. My research will focus on extending the model to predict market behaviors after the crash. I will adopt some assumptions in LPPL (i.e., imitation behaviors among traders) as well as some more theories from other literatures, and follow the similar track to construct a model that predicts when the market will stop crash. I will then fit the model into financial time series to examine the accuracy of the model.
Increasing crop yields has always been a global issue. One of the largest studies of domestic hunger, Hunger in American 2010, reported, hunger is increasing at an alarming rate in the United States (Feeding America). My research this summer focuses on identifying a bHLH gene, ms32, which promotes fertility in maize (corn), the most widely grown grain crop. As the anther – the male reproductive organ in plants – matures during early development, five distinct layers are formed and required for meiosis to function properly. One of the five layers, the tapetal layer, is crucial for the development of pollen grains, which are the male gametes, and is regulated by the ms32 gene. A mutant in this gene causes excess cell division in the tapetal layer, causing pollen mother cells to collapse, rendering the plant sterile. A better understanding of this bHLH gene will prevent additional division in the layer […]
Butterflies are known for the remarkable patterns and colors of their wings. There are precisely arranged rows of microscopic single-cell scales across the wing surface. The color of scales can result from either the biosynthesis of pigments within the scale, or from structural coloration (sometimes both). Structural colors, such as iridescence, are of particular interest because they originate from the interaction of light with complex nanostructures that are found within or at the surface of each scale. A remarkable example of iridescence is seen on the wings of the Gulf Fritillary butterfly, Agraulis vanilla, where spots appear silver and almost reflective as a mirror. I am interested in how scale stacking contributes to overall reflectivity, and how actin contributes developmentally to the particular structure, and therefore iridescence, of a silver scale. I will be looking at Gulf Fritillary butterfly wings at the larval, pupal, and adult stages. My work will […]
Metalloporphyrins are found in various different organisms ranging from humans to plants. Metalloporphyrins consist of a porphyrin macrocycle with a coordinated metal atom at their center. They are part of many biological systems such as chlorophyll, vitamin B12, cytochrome P-450, and hemoglobin. Synthetic metalloporphyrins are used as commercial dyes and catalysts in the design of solar cells, molecular electronics, and supramolecular building blocks. The metalloporphyrins interaction with light plays a critical role in many systems therefore it is important to characterize the molecules interactions with light. The goal of my research project is to investigate the molecules interaction with light by studying the ionization of the ground and excited state using a femtosecond laser to conduct a pump-probe experiment. Metalloporphyrins of various metal centers and substituent groups on the porphyrin macrocycle will be studied in order to find how each variable affects the ionization process and excited state dynamics.
With a rapidly increasing amount of tropical forest threatened by logging and land conversion, there is growing concern about retaining species diversity, and in turn, ecosystem sustainability. My research uses methods from the Operations Research field to incorporate ecological considerations for strategic planning in multi-use tropical forest landscapes. While past research has primarily focused on identifying sites for placing permanent reserves, my research develops optimization tools to create algorithms that apply principles of ecological sensitivity to both reserve patterns and harvest scheduling at once.I am utilizing recent advances in numerical optimization of integer programming problems to include spatial and temporal factors that until recently were difficult to solve with such precision. Varying harvesting patterns in response to species-specific spatial and temporal patterns in addition to reserve planning represents a promising new method inform future sustainability standards for forest management, thereby helping to conserve species diversity and maintain ecosystem function.
Why do children spend so much time engaged in pretend play, imagining fictional scenarios? Could children actually be learning new things through this process, exploring new possibilities inaccessible to them in daily life? My SURF project seeks to explore whether imagination can indeed enable children to learn about and successfully intervene on novel causal structures, even in the absence of a demonstration of the structures. Children will be introduced to a novel causal structure, and will be asked to choose one of three possible interventions on the structure to produce the highest probability of a desired result. Will the process of imagining outcomes produce higher accuracy in the absence of a demonstration of a novel causal system? This project not only serves as my honors thesis in Psychology, but also explores the little-understood relationship between imagination and probabilistic causal learning in preschoolers.
My research is about the efficacy of verbal retrieval practice, the act of verbally explaining or telling someone else about learned material. So much of academics is focused on studying or re-reading material when really, telling or explaining it to someone may be more beneficial for memory and comprehension. Along the lines of the testing effect, in which a student shows better memory for items that were tested as opposed to simply studied, verbal retrieval practice serves as a form of testing that may be in line with Transfer Appropriate Processing. My research will explore quantitatively how much verbal retrieval practice may affect memory more than studying or re-reading alone.
In my research, I aim to explore the mechanisms behind why Asians experience more difficulty in disclosing personal problems and approaching others for help in various situations (especially emotionally) than when compared to Westerners. Do different styles of communication (indirect vs. direct) or differences in the implicit sense of power status (high vs. low) moderate this interaction? Might Asians show preference seeking certain people to whom they disclose their problems or seek help from? I hope that this research could help shed light on the acculturation process and success of Asian immigrants in flexibly adjusting to the host culture. In addition, I also hope that exploring the reasons why Asians have a harder time seeking others help could give mental and physical health professionals some insights on how to face Asians and give them better treatment methods. Lastly, I hope this research could give a better understanding to people of […]
Jhoole, a textile production NGO based in Madhya Pradesh, India, formed in 2008 through a dialogical need from sari weavers that were working under indentured conditions. Since its formation in 2008, Jhoole has provided collective ownership, secured creative freedom over design/production, implemented sustainable agricultural practices, and supplied living wages to these female artisans. However, in March 2012 after reading Marx, Hannah Warren, the founder and Executive Director of Jhoole, un-incorporated Jhoole in an effort to dismantle institutional hierarchies that limited the extent to which local stakeholders were able to direct the activities and assets of the organization. My research involves both a case study analysis of the effects of Jhoole un-incorporating and a larger deconstruction of the term economics of well-being in its relation to the proto-Indian social enterprise/NGOs efforts at effectively (or ineffectively) promoting such an economics of well-being in India.
