Years with LPL: 2001 to present

 

Dr. Showman investigates the dynamics and evolution of planetary atmospheres and interiors. His atmospheric research currently focuses on giant planets—Jupiter, Saturn, Uranus, Neptune, and the hundreds of giant planets that are being detected around other stars.

In addition to the active research areas described above, Dr. Showman also has a long-term interest in the atmospheric dynamics, climate, interior state, and geophysics of the terrestrial planets Earth, Mars, and Venus. A new area of interest is the atmospheric structure and dynamics of brown dwarfs.
