Nanoemulsions, kinetically stable oil-water dispersions, have attracted the interest of a diverse set of scientists for their application to material synthesis and within the pharmaceutical, cosmetic, food, and oil industries. However, a molecular picture of the interfacial region has eluded researchers due to the difficulty of measuring this region without interference from the bulk solution. Using Vibrational Sum-Frequency Scattering Spectroscopy we probe the vibrational modes of surfactant species present at the curved nanoemulsion interface. We seek to learn about the structure of this interfacial region and the manner in which surfactants assemble at the curved oil-water interface and how this structure contributes to the formation and stabilization of nanoemulsions. As we complicate the system from simple models to mixed chemical systems (more reminiscent of current

Outside the Lab
Outside of the lab you can find me running the paths around Eugene, biking, and occasionally inside a coffee shop reading a good book.
