I attended Columbia University where I earned a Bachelor of Arts degree in Neuroscience & Behavior as well as Comparative Ethnic Studies. I completed my graduate education at Relay Graduate School of Education where I earned a Master of Arts in Teaching. Finally, I am currently certified as a general education teacher in New York State. But my passion for teaching extends much further back than my college days.

Ah-hah! This says, Match the word to the definition. My eight year old student, a recent immigrant from Cuba, beamed with pride as he read the directions on his homework without help for the first time-- and at 13, I realized that I wanted to spend my life creating as many ah-hah! moments as possible. After three years as a middle school science teacher in New York City, and many more years as a reading, math and science tutor, I found that for too many of my students, learning boiled down to passively memorizing information well enough to earn a good score on the next exam. As a result, many of my students viewed their education as irrelevant, boring, useless and ultimately devoid of those fantastic ah-hah! moments I found so inspiring.

As an educator, I made it my mission to challenge my students' typical classroom experiences and to instead teach in a way that fosters a love of learning in my students. I believe that students learn best when learning is active, when practice is messy and when content is made relevant. Regardless of the subject, I teach students using active learning experiences in tandem with scaffolded questions that allow students to build their own understanding of content, and encourages them to ask questions of their own. I help students learn more deeply by helping them realize that learning is a process. And as part of the process mistakes they make are not failures, but rather opportunities to slow down, analyze their thinking, and ultimately correct their misconceptions. Finally, I strive to make everything I teach relevant. I want my students to think of their education not as information to be memorized and applied on their next exam or assignment, but as a way of understanding themselves and their worlds more thoughtfully and critically.

When not teaching, I enjoy reading science-fiction novels, learning about new scientific breakthroughs, exploring new music, and spending time with friends and family over home-cooked meals.
