Perception, or the ability to perceive the world, is one of the remaining missing components for allowing robots to enter our daily environments. However, its current state-of-the-art performance is far from accurate. This summer, I will explore several machine learning techniques for improving perception. For instance, I will use distance metric learning to improve upon the euclidean distance that is widely used for comparing data points. Preliminary results show that algorithms such as Large Margin Nearest Neighbor can greatly improve k-nearest-neighbor performance for SIFT features, improving perception performance. I also […]

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 […]

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 […]

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 […]

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 […]

Choanoflagellates are single-celled eukaryotic organisms that are the most recent ancestor to multicellular animals. As such, they possess most of the proteins required for the transition to multicellularity. One choanoflagellate protein in particular, Homer, has been shown through immumofluorescence to localize to the nucleus. I will be using transmission electron microscopy with Immunogold staining and membrane fractionation to discover the sub-cellular localization of Homer. In animals, Homer plays a crucial role in adhesion and scaffolding at the synapses of neurons. Since neuro-sensory systems are unique to metazoans, I hope to […]

Karuk is an endangered language indigenous to Northern California. One of its most interesting features is its large variety of verbal prefixes and suffixes, expressing everything from person and tense to the direction of motion relative to the Klamath River. For my summer research project, I will be focusing on just one suffix, the essive, which roughly provides the meaning of being in a certain condition. For example, when applied to the verb imus, to see, the result is imus-ahi, to look like. I plan to take a more modern […]

Human Cytomegalovirus Virus (HCMV) may go unnoticed in people with healthy immune systems; however, this opportunistic pathogen can be life threatening to immunodeficient individuals including AIDS patients, newborns, and transplant patients. Nucleic acid molecules such as ribozymes are promising gene – interfering agents. This enzymatic RNA accomplishes gene-interference by targeting and cleaving a specific region of mRNA e.g., viral mRNA. In my research I will take advantage of the ability of Salmonella bacteria to enter human cells and transfer genetic material to host cells, leading to efficient expression of the […]

Negatively charged nitrogen vacancy centers (NV- centers) in diamond consist of a nitrogen atom next to a vacancy in the carbon lattice. With their small size, these color centers promise magnetometry (measurement of the magnetic field) with an unprecedented combination of sensitivity and spatial resolution. For this application, optically detected magnetic resonance (ODMR) signals must be thoroughly understood. We obtain ODMR signals by focusing 532 nm (green) laser light onto the sample, applying a scan of microwave frequencies by pressing a wire against the diamond surface, and measuring the red […]
