Education:

Ph.D., Mathematics, Indiana University, 1982
B.A., Mathematics and Physics, Oberlin College, 1976


Career Highlights:

Cheney held positions at Stanford University and Duke University before moving to RPI in 1988. She has held visiting appointments at NYU's Courant Institute (1987-1988), at the Institue for Mathematics and Its Applications (1994-1995, 1997, and 2005), the Mathematical Sciences Research Institute (2001 and 2010), the Naval Air Warfare Center Weapons Division (2002), the UCLA Institute for Pure and Applied Mathematics (2003), and the Air Force Research Laboratory (2007-2008).

Cheney has received several awards, including the Office of Naval Research Young Investigator Award in 1986, a National Science Foundation Faculty Award for Women in Science and Engineering in 1990, the Lise Meitner Visiting Professorship at Lund Institute of Technology in 2000, and a National Research Council fellowship in 2007. She has served on the SIAM Board of Trustees, and currently serves on the editorial boards of three journals. She is a Fellow of the Institute of Physics and a Fellow of SIAM.

Research Areas:
Most of her work has been on the inverse problems that arise in quantum mechanics, acoustics, and electromagnetic theory; since 2001, she has been working on radar imaging.
