Yoon Han
As part of Professor Shaowen Baos lab, Yoon will expand our understanding of the influence of sensory input on information processing during an epoch of early development known as the critical period. At the behavioral level, he will investigate how early experience of single-frequency tone pips influences frequency discrimination ability in rats. At the physiological level, he will examine the auditory cortex (A1) of tone-exposed rats to extract response properties of the cortical neurons, such as the characteristic frequency, spontaneous firing rate, maximum firing rate, and tuning bandwidth. At the […]
Elizabeth Nicole Wilcut
Elizabeth plans to design, construct and test a prototype of a low temperature refrigerator, in order to demonstrate an efficient and simple method for cooling to temperatures below 1 Kelvin. Currently, dilution refrigerators are used to achieve such low temperatures, a technology that is complicated, expensive and experimentally demanding. By pioneering the use of a refrigerator that uses a flowing electrical current through superconductor junctions, Elizabeth’s prototype will improve on the cooling power of some preliminary electronic refrigerators by more than four orders of magnitude and create a technology that […]
John Weedin
A double major in Molecular & Cell Biology and History, John intends to investigate the function of polysialic acid (PSA) on the cellular membranes of cancer cells. Polysialic acid is a relatively long, negatively charged sugar polymer composed only of sialic acid monomers. While the role of polysialic acid in neural and fetal cells has been well studied, information regarding its role in tumor cells has not. John hypothesizes that the long molecule disrupts the cell-cell interactions that prevent uncontrolled cell division, allowing tumor cells to rapidly multiply and expand. […]
Manasa Basavapatna
A Molecular and Cell Biology major, Manasa will study the Dengue virus (DEN), which causes the most prevalent arthropod-borne viral illness in humans worldwide, with an estimated 2.5 billion people at risk. Primary infection results in dengue fever (DF), an acute disease. In primary infections, DEN induces an effective immune response that may involve interferons (IFNs). IFNs are proteins produced by cells in response to various stimuli, especially viral infections, and are known for their antiviral and immunomodulatory effects. The role for IFNs in offering protection against the dengue virus […]
Nika Cyrus
Folate deficiency still remains as the primary culprit for childhood mortality, and a major cause of atherosclerosis and cancer. Yet, we lack a precise method for determination of the long-term folate status of patients. The objective of Nikas project is to develop a more accurate method of quantifying long-term folate status through elucidation of Red Cell Folate kinetics. It is assumed that Red Cell folate (RCF) remains constant in the circulation; nevertheless, erythrocytes are capable of specific uptake of folate, suggesting that RCF is dynamic. Nika will perform experiments in […]
Ki Won Yoon
Ki Won’s project involves an investigation of cosmic microwave background radiation (CMBR). CMBR travels to us over cosmic distances, beginning its journey a short time after the Big Bang, the birth of the Universe. In essence, it is a snapshot of the aftermath of creation. Specifically, Ki Won will study the polarization characteristics of CMBR, using a polarization-capable radio telescope being built at the Lawrence Berkeley National Laboratory. Ki Won will develop a detailed plan for the use of the telescope to detect CMBR polarization, write software to automate the […]
Aida Sadikovic
Aida’s Senior Honors Thesis in Molecular & Cell Biology will focus on investigating the mechanisms behind the murine immune response to Listeria monocytogenes. L. monocytogenes is a ubiquitous intracellular human and animal pathogen that can spread from cell to cell via actin-based motility. Previous studies have shown that VASP-binding deficient strains of L. monocytogenes exhibit slow motility and virulence attenuation compared to wild type strains, especially in the liver during secondary murine listeriosis. She hopes to gain a better understanding of the reasons behind this tissue difference and to determine […]
Lorraine M. Wang
The ability of cells to respond to extracellular signals is mediated by signal transduction networks that almost invariably include a cascade of protein kinases. One family of protein kinases that is universally conserved in eukaryotes is called the p21-activated protein kinases (PAKs). The genome of Saccharomyces cerevisiae has revealed a closely related PAK-type protein kinase called Cla4. Cla4 is required for the proper assembly of a novel cytoskeletal structure that is essential for cytokinesis thereby providing an important checkpoint in the highly regulated cell cycle. Lorraine will be investigating the […]
Yu Lei
Nanocrystalline materials have shown promise in many applications, such as light-emitting diodes, solar cells, biomedicine, optoelectronics, etc. Shape-controlled nanocrystals are important because different geometries of nanocrystals possess various electronic properties which can be tailored to their application. In this project, Yu will conduct synthesis experiments of Cadmium Telluride (CdTe) by varying the amount of solvent. By analyzing nucleation kinetics in the synthesis of the CdTe, Yu hopes to develop a mechanistic explanation for crystal branching and increase the reproducibility of the tetrapods shape syntheses. Moreover, this approach to understanding CdTe […]
Anita Lee
Through a series of experiments conducted at a UC Berkeley laboratory greenhouse and at the Agroforestry site in Five Points, California, Anita will investigate the physical, chemical and biological factors that produce high rates of selenium volatilization from the soil-Salicornia system. An essential trace element that becomes toxic at high concentrations, selenium is currently a big concern in the San Joaquin Valley. The volatilization of selenium is a promising new technique for land reclamation. Whereas traditional phytoextraction methods sequester selenium in plant tissues, volatilization can potentially remove a significant amount […]
