Bio

My love for mathematics started as a love for computer programming. I spent hours in middle school and high school writing programs in BASIC, Pascal, and C++.

I did well in my computer courses at Brandeis, and in my junior year I became a Teaching Assistant for the intro programming course. I spent so much time working with students that were struggling, and I quickly realized that this is what I wanted to spend my career doing.
At the same time, the computer science degree required many math courses to complete. As I continued taking these courses, I realized that my love for writing code was because I loved the mathematics behind programming.

Once I finished my undergrad work, it was an easy decision to continue studying mathematics and mathematics education. I love teaching and working with students, and I am amazed at the many ways in which mathematics explains the world.
I try to instill a love and passion for mathematics in my students, and I hope that they can at the very least gain an appreciation for math and how it helps us in our everyday lives.


What I Love about Emmanuel:

In my short time so far at Emmanuel, I am impressed with how much our students want to succeed. They are also passionate about helping each other and the community at large. It is easy to teach students with a thirst for knowledge and a drive to be successful.

Research Focus

My research focus is in the area of undergraduate mathematics education. Specifically, I focus on student understanding of sequences and series in second semester calculus courses as well as proof comprehension in abstract algebra and real analysis.
