Hudson's interest in space developed as a child raised during the
space race who had her own childhood telescope. Starting with her Ph.D. research, Hudson worked on the spread
F problem, a phenomenon known to impact the transmission of signals by satellites. the electrostatic shocks they measured accelerate electrons to make the
auroras that can be seen at night in high latitudes. Hudson's research on
geomagnetic storms, disruptions in the Earth's
magnetosphere, establishes the conditions that cause radiation belts to form during these storms. From 2002 until 2013, Hudson co-lead the National Science Foundation-funded Center for Integrated Space Weather Modeling. which has consequences for technology used on Earth. Hudson has also examined the movement of particles in radiation belts, the
Van Allen radiation belts, that surround the Earth.
