Plasma dynamics
From Memory Alpha, the free Star Trek reference
In physics, plasma dynamics was the study of plasma, specifically aspects of plasma physics.
Amanda Rogers' Starfleet Academy transcript, prior to her joining the Q Continuum in 2369, was considered "impressive," by Doctor Beverly Crusher, who noted that Rogers' work was "pretty well-rounded," covering neurobiology, plasma dynamics, and eco-regeneration. (TNG: "True Q")
