Faculty Mentor: Sudhir Nayak Students: Jen Aleman My project focused on discovering the mechanisms of gld-1 regulation. In C. elegans, GLD-1 (defective in Germ Line Development) is an RNA-binding protein and acts as a translational repressor. The GLD-1 protein binds to mRNAs in order to block translation and prevent inappropriate expression of their gene products.… Continue Reading

Genetic variation in native and invasive broomsedge grass populations
Faculty Mentor: Janet Morrison Students: Brian Giacopelli & Michael Readinger Andropogon virginicus is an important grass in old field succession that is native to the eastern regions of the United States and has also been introduced in California and Hawaii. In Hawaii it is considered invasive. In about half of the Eastern populations, A. virginicus… Continue Reading
Development of an in vitro system for measuring fictive breathing in the neonatal brainstem/spinal cord
Faculty Mentor: Jeffrey Erickson Student: Robert Myers Pet-1 gene deletion results in a significant loss of neurons that comprise the brainstem serotonin (5HT) system. This selective loss of 5HT neurons results in abnormal autonomic function, particularly during early postnatal development. Pet-1 mutant (knockout) mice exhibit a lower resting breathing rate, a higher incidence of apneas,… Continue Reading
Effects of urbanization and extreme weather on the life cycle of a common songbird, The Carolina Chickadee
Faculty Mentor: Luke Butler Students: Sydney Hope & Frank Stabile Urbanization has important effects on the biology of a wide variety of organisms. Likewise, global climate change has altered the timing of important steps in the life cycles of many organisms. In birds, the annual replacement of the plumage is a critical life stage and… Continue Reading
Expanded Investigations into Remediation of Metal-Contaminated Water Through Electrospun Biopolymer Nanofibers
Faculty Mentor: Matthew Cathell Student: Melissa Bradley This project began during MUSE 2011 and is an expansion of ongoing research dealing with remediation of polluted water. The goal of our research is to create biopolymer fiber mats that successfully filter toxic metals out of water. These mats were made from the biopolymer alginate, a water-soluble polymer… Continue Reading
Development of a Damage Model for Fiber Reinforced Composite Materials
Faculty Mentor: Karen Yan Students: Daniel Christiansen A fiber reinforced composite (FRC) consists of two parts: high strength fibers and the resin that hold layers of these fibers together. The directional specific strength and relative lightweight nature of these materials are perfect for advanced applications such as aerospace and automotive engineering. While in most practical… Continue Reading
Modeling of friction-induced squeak of Ceramic-on-Ceramic Hip Implants
Faculty Mentor: Manish Paliwal Student: Mark Sidebottom Ceramic-on-Ceramic (CoC) bearings are an ideal choice for a total hip replacement because the ceramic bearings long wear life than Metal-on-Metal or Metal-on-Polyethylene bearings. Recently CoC hips have been reported to squeak in 1-10% of the patients. A study by Chevilotte et al. showed that in vitro testing… Continue Reading

Effect of Inlet Flow Conditions on Flow Uniformity Within a Fuel Cell Manifold
Faculty Mentor: Lisa Grega Students: Manthan Kothari & Andrew Specian Fuel cells have the potential to become the next leader of renewable energy and have been researched in many areas of science to maximize this potential. Over the summer our lab worked with a scaled up model of a PEM (Proton Exchange Membrane) fuel cell… Continue Reading
Wirelessly-Controlled Relay System for Power Engineering Laboratory
Faculty Mentor: Anthony Deese Student: Tyler Wardlow The goal of the project was to design and build a wireless three phase relay controller for use in the new Smart Electric Power Systems Laboratory in Armstrong Hall. This device will be an addition to the lab and will provide an increase in capabilities for future experiments… Continue Reading
