Biography

I have a B.S in Chemistry from the University of Virginia, and I did research in the field of nanomaterials in applications to electrochemistry. I am a rising Ph. D student at the University of Florida's Chemistry Department (inorganic division). I was a teaching assistant at UVA for Organic Chemistry Lab for Majors, a three credit lab course where I directly supervised nine students, graded their assignments, and held office hours to help them. Of my own volition, I also held two extra review sessions over the course of the semester where I gave mini-lectures, workshopped practice problems, and answered questions for my students.
