Education and career
Wall was born on October 21, 1971, in St. Louis, Missouri, in a working-class family; she attended desegregated public schools, and supported herself in college at Truman State University through multiple part-time jobs. She majored in mathematics there, graduating in 1993. She went to Iowa State University, intending to do graduate study in mathematics, but switched to statistics after a semester. She earned a master's degree there in 1995 and completing her Ph.D. in 1998. Her dissertation, On nonlinear structural equation analysis, was supervised by Yasuo Amemiya.

After completing her doctorate, she joined the University of Minnesota as an assistant professor of biostatistics in 1998, earned tenure there in 2004, and became a full professor in 2010, the same year in which she moved to Columbia University. At Columbia, she headed the Division of Biostatistics and Data Coordination in the Department of Psychiatry from 2012 to 2017, and after leading the effort to rename the division to Mental Health Data Science in 2018, has continued to direct it since then.
