Lalitha Vasudevan​

Lalitha Vasudevan​ started school at 2.5 years old in Calcutta, India. It was a fact of which her parents were very proud. As a curious child who was always asking questions, she excelled. At 4, the family immigrated to the United States. She excelled there, too. School was a place where she felt free to have aspirations, chase success and develop confidence.

In college, she had what she calls a “renaissance” semester, when she took a sociology class, a linguistics class, an urban education class and a psychology class. She became fascinated by communication: its processes, nuances, and the freedom it allows us to move through the world in the way we wish.

When she began working with young people whose experiences in school were not empowering or affirming, she became curious about their stories. Her passions for inquiry, language and story coalesced into an academic career that developed at Teachers College. Today she is a faculty member and program coordinator of the
C​ommunication, Media, and Learning Technologies Design Program​ in the department of M​ath, Science and Technology.​

Her focus shifted from traditional critical research on what wasn’t working for these young people, to cultural production projects that honor multiple literacies and help them tell their stories. At TC she co­leads the C​enter for Multiple Languages and Literacies (CMLL), ​the C​ivic Participation Project (CPP) ​and the M​edia and Social Change Lab (MASCLab). ​Just as she uses technology and dialogue to bring these stories out in multihued ways, Professor Vasudevan challenges her own students, ­­future teachers, and researchers­­ to collaborate, keep listening, and keep inquiry open.

Dr. Yolanda Sealey-Ruiz

Growing up in the South Bronx in the 1980’s, Yolanda Sealey-Ruiz learned that diligently pursuing education was the way to gain access to the resources and experiences her parents couldn’t afford to provide for her.

While she excelled academically competing against students from a similar background to hers throughout high school, succeeding in the university and in postgraduate studies was a profound challenge. It was Professor Sealey-­Ruiz’s passion for learning and love for writing that helped her overcome those difficulties and process her experiences. Today, as Assistant Professor of English Education at Teachers College, she has made the educational autobiography a centerpiece of her teaching philosophy

and is known for taking authentic and compassionate interest in the lives of her students.

She is also deeply engaged in the Teachers College community, running programs such as the Racial Literacy Roundtable, and encourages her students to harness their unique life experiences to grow into thoughtful, reflective teachers and mentors to the young people in their lives.

Chris Emdin

When Christopher Emdin was a high school student in Flatbush, Brooklyn, he hated science class. While he was perpetually curious about scientific concepts in nature and technology, he felt stifled by the lack of interactivity in the science classroom and like many students, kept his curiosity outside of school... along with his love of rap and hip­-hop culture.

Years later, as an educator and researcher, Professor Emdin found a way to bridge the gap between these passions and has developed a unique hip­-hop pedagogy for urban science education, which he’s brought to public schools throughout New York City, and to Teachers College as an Associate Professor in the Department of Mathematics, Science and Technology.

At its core, his philosophy brings the expressive, creative, community-­oriented sensibilities of hip­-hop into the classroom, where he strives to make students—particularly students of color who have

historically been excluded from academic success in the sciences—feel comfortable, engaged, inspired and aware that their personal passions can actually fuel their education.

At TC, he teaches future science educators about the value and scope of hip-hop culture as a tool for connecting with students, providing them with frameworks to develop curricula based on culturally relevant pedagogy in the 21st century.
