PhD, Biochemistry, University of Chicago

Mariana joined Congressional School in 2019.

Her research focused on how human cells behave differently in the context of disease, from cancer to viral infection. After participating in Science outreach programs throughout her research career, Mariana decided to devote herself full-time to Science education. She spent four years teaching Middle School Science at an independent school in Northern Virginia and a public charter school in DC.

Mariana has lived in 5 different countries and is fluent in English, Spanish, and French. In her free time, you’ll find Mariana playing with her twin boys, cuddling her many pets, and enjoying good books.


"Each class presents a unique set of challenges and opportunities. I learn as much from my students as they learn from me, and I wouldn't have it any other way."
