Sharoll Fernandez Siñani — Founder & Executive Director
Aymara educator, policy strategist, and artist, Sharoll leads Zera Bolivia’s model for community-owned learning. She is the first Indigenous Aymara woman from Bolivia to graduate from Harvard (Ed.M., Education Policy & Analysis; Power, Identity & Justice), admitted via a rare merit-based exception. Over the past decade, she has designed and implemented creative education programs from the Andes to New York, integrating high-context Indigenous knowledge with learning science and systems design. Her work emphasizes real community agency—clear governance, transparent measurement, and educator training—so capacity stays local and outcomes endure. As a museum-exhibited artist and the author of the trilingual To Senkata and My Dead, she uses art to catalyze civic dialogue and critical thinking alongside rigorous pedagogy. She has advised leaders of multi-million-dollar organizations and builds partnerships that align cultural integrity with scalable impact.
Focus areas: education policy and learning design; measurement & evaluation; Indigenous governance and community capacity; arts-based pedagogy; behavioral economics and systems design.
Selected work: Metamorfosis visual series; exhibitions including the Queens Museum and Harvard Graduate School of Education.
Languages: Spanish, English, Italian.
About Aymara: I did not learn it as a child—the transmission was interrupted in my family due to survival and social mobility strategies that prioritized Spanish—and today I maintain a disciplined (re)learning process to recover it.
Sharoll’s leadership positions Zera Bolivia to deliver evidence-based, culturally rooted programs that move communities from recipients of aid to architects of their own prosperity.
