NYU Tandon School of Engineering

Math/Chemistry Tutor – NYU Tandon School of Engineering:
Achieved higher student exam scores by developing weekly lesson plans for students. Motivated students by providing advice on the college process and engineering curriculum

I’ve been a Math and Chemistry tutor for four years for peers in my undergraduate studies, and a private tutor for middle schoolers. I enjoy teaching math and science from 6th grade and beyond. My courses offer a keen understanding in the fundamentals of a given topic.

I grew up and studied in New York City and graduated with a bachelor's degree in Chemical and Biomolecular Engineering from New York University in 2018, and I currently working as an Assistant Chemical Engineer for the City. My favorite part about tutoring is helping students find their passion and inspire self confidence in science and mathematics.

I believe teaching should be both fun and intellectually rewarding for both the student and tutor. With this in mind, I aim to achieve comfort and confidence in my students when learning about fundamental principles in math and science.
