In 1998, Alexandra co-founded the Chiapas Media Project, an award-winning binational organization that trained over 200 Indigenous men and women in video production in Chiapas and Guerrero, Mexico. In 2004, she was awarded a Guggenheim Fellowship for the Latin American Indigenous Video Initiative (LAIVI). In 2007, she received a Fulbright Scholarship for the Indigenous Audiovisual Archive (IAA) in Oaxaca, Mexico. During this time, she also produced five short documentaries in collaboration with Mexican human rights organizations—some of which received international awards.
In 2010, Alexandra founded the Americas Media Initiative, a nonprofit that works with Cuban filmmakers living in Cuba, supported by the Ford Foundation. She has organized four Closing Distances / Cerrando Distancias documentary programs, bringing U.S. documentaries and filmmakers to audiences in 14 towns across Cuba. In 2013, she co-curated the New Cuban Shorts Program at MoMA’s Documentary Fortnight Series.
For the past five years, Alexandra has collaborated with ProMedios to create the Center for the Preservation of Community Audiovisual Archives (CEPAAC), based in San Cristóbal de las Casas, Chiapas, which has received grants from IMCINE (Mexico) and UCLA-MEAP (U.S.). In 2023, she was awarded MacDowell and Bogliasco artist fellowships to work with footage from the CEPAAC archive. She is currently producing a series on immigration in Chicago, funded by the Walder and Field Foundations.
