The purpose of my project was to express and measure in vivo activity of the TrpM enzyme in E. coli. TrpM is part of a methylase family of enzymes that adds a methyl group to a base molecule, in the case of TrpM, the base molecule is the aromatic amino acid tryptophan. To do this […]
A23: Biomedical Applications of Sensing Multi-State Metabolic Behavior from Cellular Autofluorescence
One way to detect metabolic change in cells is through a method called laser-induced fluorescence spectroscopy which involves exciting the cellular sample using a laser and measuring the spectrum of its autofluorescence emission. In order to detect metabolic change, we monitor autofluorescence emission in real time, and through past studies we are able to quantify […]
A17: Combating Antibiotic Resistance
Our research group has been studying the effects of antibiotic resistance in our society. We chose to study this topic because it is a major issue that is affecting people all over the world. Our research project involved us learning about antibiotics from the beginning; when they were first produced, how they work, why bacteria […]
B47: Physics Education: Introductory Student Self-Efficacy and Problem-Solving Approaches
Physics education research focuses on how to improve the effectiveness of student learning and curriculum development. This area of physics education specifically focuses on students in introductory physics courses and how their self-efficacy and problem-solving methods change over the course of a semester. By tracking the improvement or deterioration of a student’s abilities, the Miami […]
C09: Burial Rates of Carbon, Nitrogen, and Phosphorus in Sediments of Three Retention Ponds in a Watershed with Changing Agricultural Practices
Within the area of freshwater science, researching small-scale retention ponds is useful to determine how successful they are at trapping excess sediment, carbon (C), nitrogen (N), and phosphorus (P), which can all have negative environmental effects (such as contributing to global climate change or harmful algal blooms) if left unchecked. The goal of my research […]
B57: Gut Microbes and Atherosclerosis: How Your Microbiome Is Influencing Your Health
Because of its variation across different individuals even in similar environments, the gut microbiome can influence the health of different people in different ways. One major example is the way that different microbes consume quaternary amine compounds (QAs) that are prevalent in the human diet, such as in red meat and wheat. Some gut microbes […]
B24: Characterization of high molecular weight polyphenols by FT-ICR MALDI-MS and HPLC
Condensed tannins are high molecular weight polymers, comprised of flavan-3-ol monomers stabilized by C-C interflavan bonds. Condensed tannins are found in most higher plants, and affect food properties such as astringency and protein availability, N- and C-cycles in soil systems, and agronomic properties such as insect and pathogen resistance. Tannins are highly sorptive molecules, making […]
B20: Synthesis, Identification, and Characterization of Co(II) Spin Crossover Complexes
Spin Crossover (SCO) Complexes are coordination complexes that exhibit huge changes in magnetic properties under external stimulus, and thus this abrupt change attracted attentions to be studied. This shift in property is a result of transition of the center metal between high-spin and low-spin states, which are two electronic states of the d orbital in […]
C52: Quantum Mechanical Anti-Lasers in Optical Cavities and Waveguides
First demonstrated in 2011, Coherent Perfect Absorption (CPA) is a robust technique to achieve perfect absorption when shining a coherent light on a loss medium with no apprent reflection, behaving just like an ideal blackbody. The technique is colloquially referred to as an “anti-laser”, for it is exatly the lasing process played backwards in time. […]
B40: Acclimation of an Antarctic Alga to Environmental Stress
In studying the Antarctic psychrophile Chlamydomonas sp. UWO 241, one topic of particular interest has been the novel mechanisms it uses to deal with stress and maintain photosynthetic capability in its environment. Previous work established that UWO 241 uses constitutively upregulated photosystem-I driven cyclic electron flow to deal with high salinity stress. The goal of […]
