circletwitterbird @CamilaSegura

Even though Camila has spent most of her adult life in academia, after obtaining her PhD in literature from Columbia University, she realized radio was her true passion.

Luis Fernando Vargas Vega


circletwitterbird @LuisVarvega

Costa Rican. As a teenager he wanted to be a philosopher, yet he became a journalist. He has written about art, music, literature, and cuisine in various Costa Rican media outlets. He reads to save himself, though he is not sure from what. His life belong to two cats, Quentin and Pelusa. He’s 20-odd years old, but many call him “Sir”: they have been very good or badly lived–the years–. He’s still undecided on that.

Laura Rojas Aponte

Program and Growth Coordinator

circletwitterbird @amarillopopis

Laura has a personal purpose: strengthening the culture of podcasting in Spanish. For years, she’s been listening to her favorite shows in the mornings, and fantasizing about the idea of everyone sharing that same experience. Her mission led her to create several programs (right now, she spends her nights producing her podcast Cosas de Internet). That purpose also led her to quit many jobs in the past, looking to get closer and closer to the podcasting world —and further apart from advertisement. Eventually, she found a place at Radio Ambulante.

Lisette Arévalo


circletwitterbird @larevalogross

Ecuadorian journalist. She was a fellow at the Toni Stabile Center for Investigative Journalism at Columbia University, where she got her master's degree and focused on audio storytelling. Before that, she worked at Ecuadorian digital magazine GK, where she did fact-checking and wrote about gender violence and sexual and reproductive rights. She works and lives in Quito.

David Trujillo


circletwitterbird @davidtru08

He was afraid of the radio, but he let himself be taken by it. After studying journalism, he began to write in different Colombian and Latin American magazines about travel, ecology, gastronomy, culture, lifestyle, science and technology. He thought of pursuing a career in the film industry, but eventually he realized he preferred staying as a spectactor. He loves asking questions and listening to answers, so journalism has become his perfect tool to move around the world. He has been living in Bogotá for the last few years.

Victoria Estrada

During the few moments when he is not in front of a screen, he likes to bike, do yoga, share music by Felisa (his partner) and read books on paper, that rare and mysterious format.

Andrés López

Sound Designer

circletwitterbird @Andres_Azpiri

When he was 10 years old and heard the song “Lemon Tree," he was sure he had to dedicate his life to music. When he turned 21, he spent a year in Germany playing in different venues and recording in the same studios as his childhood heroes. Once back in Mexico, he improvised his own studio that started growing once local bands chose it to produce their albums. In 2016 he remodeled the studio and El Limonero was born, where he produces and post produces audio for bands and films.

She is a journalist and a translator with a career that spans over a decade and which has taken her from community newspapers to global companies including Dow Jones and Bloomberg News.
