Graduate Teacher and Researcher - Colorado School of Mines Geochemistry Department (2013 - 2015)

  • Examined the effects trivalent manganese may have on natural water chemistry, with a focus on the interaction between trivalent manganese and natural organic matter (NOM).
  • Colorimetric techniques coupled with modeling chemical reaction kinetics in Mathematica.
  • Additionally led an average of three sections of Introduction to General Chemistry Lab.
  • Awarded the Chemistry Department’s Outstanding Graduate Teaching award in 2014, in part for developing extra credit exercises in environmental chemistry for my students.
