Research Assistant - Clarkson University - Potsdam, NY

(2011-05 - 2011-09)

Investigated electrochemical corrosion behavior of nanocrystalline and coarse-grained copper with differing surface roughness in sulfuric acid and sodium chloride electrolytes using cyclic voltammetry.
Collected and analyzed electrochemical data in Excel and generated Tafel plots to compare corrosion behavior.
Supported electrochemical-cell experiments with PhD researchers in aeronautical engineering and measured hardness and Young’s modulus using a nanoindenter.

Research Assistant - Massachusetts Institute of Technology (MIT) - Cambridge, MA

(2010-06 - 2012-08)

Contributed to research on poly(allylamine hydrochloride) (PAH)/silica nanoparticle anti-reflective coatings on poly(methyl methacrylate) (PMMA) substrates.
Prepared layer-by-layer coatings using a dipping system while varying PAH solution pH.
Used atomic force microscopy (AFM) to examine silica nanoparticles on PMMA substrates and spectroscopic ellipsometry to measure refractive index.
Collected transmittance and reflectance data by spectrophotometry and analyzed results in Excel as a function of wavelength.
Investigated how heating and etching silica nanoparticles affected their adhesion to PMMA surfaces.
