Profile

Previously at Microsoft Medallia FLAIR

Hello there! I'm Maria Belen, and I prefer to go by Belu. I'm a PhD student at George Mason University, advised by Antonis Anastasopoulos in the GMU NLP Lab and supported by NSF LT4CPR. My research examines how language and speech technologies support communication during humanitarian crises, especially for underserved languages. My ISCRAM work found that language models can underestimate urgency outside English. I now use interviews, mixed methods, and community centered data collection to study safer AI systems and human AI collaboration in practice. This work includes a collaboration with the humanitarian language nonprofit CLEAR Global.

Previously, I earned my Computer Science degree at the University of Buenos Aires, working on CS educational tools, applied ML in chemistry, and the state of Indigenous languages in Argentina.

Talks & Presentations

My talks on Indigenous AI draw on personal experiences navigating academic spaces, conversations with students and faculty in NLP and AI, and exchanges with Indigenous communities, especially in Mexico.

Personal note: These reflections are my own and do not represent any community. More context about my positionality below.

Community and beyond

What shapes my work

Personal interests, positionality, and community focused work.

Beyond academia

Outside academia, I'm always exploring new hobbies and challenges, including dancing, yoga, swimming, hiking, and climbing. I'm a forever amateur biologist, chemist, and astronomer. Recently in the US, I've started my Cuban salsa chapter in life...

Random facts: I studied biology and chemistry for almost three years 🧪⚗️😮, took two teacher training courses, studied folklore part time at the National School of Arts, including tango and Argentine folk dance, and participated in astronomy olympiads 🔭✨. I had so much energy...

Positionality and values

A note on where I come from

I'm proudly marrona. My parents come from rural areas in Bolivia, and I had the privilege of attending tuition free schools. I did not grow up in what is often imagined as a stereotypical Indigenous community. Like many families around the world, mine moved in search of better opportunities (some might argued it is displacement...).

These experiences tangibly shape my research interests, my understanding of inclusion, and how I navigate academic spaces. My engagement with antiracist movements in Argentina also shaped my political identification as marrona. The more opportunities I receive, the more important it becomes to stay aware of the privileges that come with them, share what I learn, and make knowledge and opportunities more accessible.

I'm still figuring out how to balance outreach work that personally fulfills me with academic and professional opportunities that support career growth. So far, I see a faculty role as a position of both power and responsibility. It could let me continue some of the work I care about and, most importantly, offer the intellectual freedom to bring great people together around shared goals.

For now, after exploring academic work on Indigenous AI, I have chosen to focus this part of my work outside traditional academic venues. I prioritize activism and community focused initiatives led by NGOs and nonprofits that help communities understand how academic and industry spaces work, develop their own positions, and pursue transparent collaborations aligned with their values and expectations. I care about concrete action and thoughtful collaboration.

Always happy to collaborate or exchange experiences, especially with women and Indigenous descendants in computer science. Reach out, y más aún si sos de LATAM.
