View Curriculum Vitae (pdf)

Sarah R. Powell is an Associate Professor in the Department of Special Education at The University of Texas at Austin and Associate Director of the Meadows Center for Preventing Educational Risk. Her research, teaching, and service focus on mathematics, particularly for students who experience mathematics differently.

Powell is currently Principal Investigator (PI) of an Institute of Education Sciences (IES) efficacy grant (RAAMPS) related to word-problem solving at Grade 4. Powell is also PI of SPIRAL, an IES grant which works collaboratively with Grade 4 and 5 teachers who provide mathematics instruction to students with mathematics difficulty. Powell is Co-PI of STAIR 2.0 (funded by IES) in which the team works with middle school special education math teachers and SCALE (funded by the US Department of Education) in which the team is replicating a fraction intervention in Grades 4-8. Powell collaborates on TIER, a project funded by the Texas Education Agency, as well as Young Academic Music and Our Mathematical World. Powell was awarded the Presidential Early Career Award for Scientists and Engineers (PECASE) in 2019.

Powell understands these efforts are a team effort, and she thanks her project leads, graduate students, research assistants, and research participants.
