Biography

I am currently entering my junior year at UC Berkeley and pursuing a B.S. in Chemical Engineering with a concentration in Business and Management from the College of Chemistry. I worked for two years at a local tutoring company, tutoring high school students in chemistry, math (calculus, statistics, algebra), physics and biology. I really enjoy teaching and helping students in any way I can.
