As Associate Scientist I in the Study Management team within Population Science, Tayanna Smith, MPH, helps process incoming survey data for Cancer Prevention Study 3 (CPS-3). Specifically, she provides critical statistical programming support and data management for CPS-3 triennial survey data alongside Elizabeth Kirkland, MPH. She assists with data clean-up and quality control processes.
Research focus and accomplishments
My research experience began during my undergraduate education in chemistry. My research team was dedicated to nanotechnology and doping nanoparticles. As a team, we studied the chemical properties of semiconducting materials, which includes metal sulfide alloy nanoparticles such as CdxZn1-xS. In other words, we could produce desired optical properties of nanoparticles and contribute to new discoveries in its current applications to LEDs, lasers, and bioimaging in medicine.
I synthesized a test protocol that involved a range of Cd to Zn ratios with a small amount of manganese (II) as a dopant to activate phosphorescence within the nanoparticle and determined that Anderson Localization minimizes optimal surface composition at a .575 Zn mole fraction. These results suggest alloy semiconductors could be used to minimize near-surface state effects in electronic devices. This discovery helped steer a future experiment for incoming research students such as probing this system with cyclic voltammetry, looking at fluorescent signals, or experimenting with Cu as a dopant.
