I began my career in research at a state university as an eager high school apprentice when I was 15. Later, when I enrolled as a college student, I continued my early research career in the Integrative Biology department by starting my own projects.

Heavy metal toxicity to honey bees:

Oklahoma State University, Reagents Professor Dr. Scott McMurry, Integrative Biology dept. 

  • Composition of heavy metal sulfates in varying doses, mg/L, mixed into sugar water for direct consumption

    • Established & maintain two apiaries off campus

    • Conducted trials on acute toxicity of heavy metals commonly found in waterways

    • Estimating environmental relevancy of data & continuing trials (post winter)


Preliminary study, Toad behavior:

Oklahoma State University, Reagents Professor Dr. Scott McMurry, Integrative Biology dept.

  • Prey orientation habits of toads analyzed for future research assessing effects of agricultural pesticides on amphibian neurology:

    • Field work: frog, toad, & snake collection

    • Husbandry of amphibians

    • Behavior trials:

      • Alteration of prey lure: color and shape (lure present in photo: body of a black cricket (Gryllus assimilis))

      • Circular directional prey orientation; L vs R rotation

      • day/night simulations 

Included (at left) is a document I wrote several years ago discussing the topic. It will not be published.


Hippocampus study:

Oklahoma State University, Dr. Alexander Ophir, Integrative Biology dept. 

  • Brain growth analysis in voles (rodents) raised in monogamous and polygynous family groups:

    • Extracted vole brains, froze, and sliced in cryostat.

    • Mounted slices in microscope slides and stained in crystal violet.

    • Analyzed stained slides under microscope, mapped out hippocampus, statistically analyzed area.
