Sierra received her Bachelor of Arts in History with an emphasis in African American studies from the historic Tougaloo College and her Master of Arts in History from The Ohio State University.  She advanced to candidacy in December 2024, where she demonstrated expertise in African American, Modern American, and Latin American History. Her research interests include the U.S. civil rights movement, Black women's care work, Black feminist theory, and Black family archival practices. 

Her dissertation project examines Black women's culture of care at a grassroots community center in Minneapolis during the height of the War on Poverty and Black Power eras. Her research has been generously supported by the Social Science Research Council (SSRC), the Mellon Foundation, Ohio State's Department of History, and Ohio State's Woman's Place. 

Sierra is also deeply passionate about ensuring historical narratives are accessible to a wide audience, thus she serves as the current Managing Editor for Picturing Black History, a history site that publishes essays of Black history geared towards the general public. 

She serves as the National Publications Director for the Association of Black Women Historians (ABWH), where she also sits on the ABWH Bibliography Committee, which launched an accessible booklist database on Black women’s history.
