Undergraduate Research Projects

Below are undergraduate research projects completed by members of the Class of 2020 through the Rinker-Ross School of Health Sciences. Click images for full-size versions of research posters.


Drake Richter

Drake RichterOrganic Matter and Fecal Coliform Pollution In Crooked Lake (Steuben County, Indiana), supervised by Sam Drerup, Ph.D.

Drake was interested in fecal coliform contamination entering Crooked Lake. Drake collected field samples from November 2019-February 2020. He measured organic matter in the stream, likely fecal coliform load, and bacterial load in the water sampled. He found total contamination did not vary between sampling dates suggesting contamination is from a consistent source (septic systems).

 


Lily Dusek

Lily DusekDetermination of Trophic State and Algal Species From Freshwater Lakes in Northeast Indiana, supervised by Sam Drerup, Ph.D.

Lily sampled surface water from eight lakes within Steuben County, Indiana. She measured environmental parameters (pH, conductivity, and transparency using Secchi Disk) as well as collected samples for algal biomass (chlorophyll a concentration) and community composition. She found that all lakes sampled showed signs of nutrient enrichment and that each lake had a unique community of phytoplankton.

 


Robert Dick

Robert DickDevelopment of a Multistep Organic Synthesis Route for Undergraduate Organic Chemistry II Laboratory, supervised by Jennifer Staude, Ph.D.

Current undergraduate organic chemistry II laboratories lack an adequate analogue to graduate and industry work. Thus, a multistep organic synthesis route combining currently used organic reactions will provide a novel laboratory experience and improve the student laboratory experience. The work describes the optimization of the first reaction, the nitration of benzaldehyde, for high purity and efficiency. The optimal conditions found are conducting the reaction at -10 ̊C for 5 minutes and mixing the nitric and sulfuric acids before adding benzaldehyde, which gives a 74% yield.

 


Brandon Dalley

Brandon DalleyGeneration of an expression vector for the E.coli SPaseI, supervised by Michael Staude, Ph.D.

Brandon Dalley was attempting to construct an expression vector by recombining the DNA of an essential bacterial protein (SPaseI), responsible for the export of virulent and other essential proteins, with a commercially available expression vector using common molecular biology techniques.

 


Myles Copeland and John Serio

Lithium as a Treatment for Varroa Mites in Honey Bee Colonies, supervised by Ira Jones, Ph.D.

John Serio and Miles Copeland were working with experimental bee hives to evaluate lithium incorporation into edible bee products. Lithium is a potentially new treatment for Varroa destructor, a mite that contributes to colony collapse disorder. It has not been approved because of potential toxicity in humans. John and Miles used fat soluble and water soluble dyes incorporated into cake icing and sucrose feeders dosed with lithium chloride to mark deposited wax and honey. This was necessary to identify which cells were likely to have incorporated lithium. Analysis of lithium at the low parts/million levels would be by microwave plasma atomic emission spectroscopy.

Thomas Rivet

Thomas RivetSite Directed Mutagenesis and Reverse Genetics system for Phi 6 on Segment S, supervised by Angela Berger, Ph.D.

Bacteriophage phi 6 is a virus that infects the plant pathogen Pseudomonas syringae. Our study focused on the importance of the nonstructural protein p12 in virus production. We generated truncated versions of the p12 protein through site-directed genomic mutagenesis. These mutated genomes will be combined in host cells to produce mutant recombinant viruses for identification of the region of p12 required for formation of the virus.

 


Sarah Ottinger

Sarah OttingerOptimizing the Analysis of Magnatic Nanoparticles by SEM, supervised by Steven Dulaney, Ph.D.

Superparamagnetic iron oxide nanoparticles (SPIONs) were synthesized and analyzed under the Scanning Electron Microscopy (SEM) to optimize imaging conditions for analysis.
