Planets are dynamic entities: their atmospheres, surfaces and interiors all evolve dramatically over time. To understand this evolution, we must piece together clues from a variety of sources, and investigate hypotheses using models that incorporate diverse physical and chemical processes.

Research in the Wordsworth group focuses on the boundary between Solar System and exoplanet atmospheres and climates. We see the planets in the Solar System simply as special cases of a much wider sample that we are only just beginning to access. One of the most exciting aspects of doing planetary research today is that the climate evolution theories we develop now are going to be testable on a grand scale in the coming decades.
