Tracy E. Northup (born 1978) is an American physicist who works at the Institute for Experimental Physics, University of Innsbruck, Austria.

She then moved to the West Coast of the United States and earned her doctoral degree at the California Institute of Technology, where she studied coherent control in cavity quantum electrodynamics under the supervision of H. Jeff Kimble.

[2][3] She then joined Rainer Blatt's group at the University of Innsbruck as an international Marie Curie fellow.

[10] These errors are understood to originate from the weakly conducting materials such as the oxide layers that form on metal surfaces.

[9] Northup has developed approaches to evaluate the impact of dielectric materials on the particles within ion traps.
