She was awarded the 2019 George E. Valley Jr. Prize by the American Physical Society (APS) for "the pico-engineering and synthesis of the first room-temperature magnetoelectric multi-ferroic material.

"[1] This prize recognizes an "individual in the early stages of his or her career for an outstanding scientific contribution to physics that is deemed to have significant potential for a dramatic impact on the field.

"[10] In 2018, Mundy was named a Moore Fellow in Materials Synthesis, was appointed to the faculty of the Physics Department of Harvard University.

She uses advanced thin film deposition techniques and electron microscopy to design, synthesize, and characterize complex materials with sub-Angstrom resolution.

Ideally, they could "enable devices that require only brief pulses of electricity instead of the constant stream that’s needed for current electronics, using an estimated 100 times less energy.
