Bredesen Center for Interdisciplinary Research and Graduate Education
I am a PhD student at the University of Tennessee, Knoxville and Oak Ridge National Laboratory with a Bredesen Center Fellowship. I research noise in protein expression at under the guidance of my advisors Mike Simpson in the DOE sponsored Center for Nanophase Material Science and Mitch Doktycz in BioSciences Division.
Cell-sized, cell-free reactions are increasing in complexity and imitating many functions of living cells. They have membranes, the ability to make proteins, form pores, grow, metabolize glucose, and communicate with cells. However making protein, the basis for every living cell, is highly variable in these reactions. Identically prepared reactions often show order of magnitude differences in the amount of protein made chamber-to-chamber. Understanding the causes of this variability will allow greater functionality for cell-sized, cell-free reactions.
I became interested in biology and genetics after creating transgenic, green fluorescent bacteria in high school AP biology. As an undergraduate junior, I worked with Dr. Mingjun Zhang to model the Young’s modulus of a silicone matrix filled with dispersed nanoparticles. Senior year, I worked with Dr. Cong Trinh to create a collection of plasmids with different copy numbers and antibiotic resistances. These plasmids were then incorporated into other work being done in the lab for better control over enzyme production and the associated metabolic processes. I graduated with a Bachelor of Science in Biomedical Engineering with a minor in Engineering Entrepreneurship from the University of Tennessee, Knoxville.
