Here are some projects I am (or have been) involved with:

Exploration of Mars:
- Mars Exploration Rover atmospheric imaging.
- Mars Exploration Rovers: Spirit dust devil movies here.
- Some interesting, but now cancelled, cameras from the Mars Surveyor Program 2001 lander.
  - The Robotic Arm Camera would have been on the '01 lander as part of the Mars Environmental Compatibility Assessment (MECA) project.
  - See some RAC field test images.
- I spent 1999 working on science operations for Mars Polar Lander prior to its crash landing.
  - The Surface Stereo Imager and Robotic Arm Camera (SSI/RAC) projects were part of the Mars Volatiles and Climate Surveyor (MVACS) payload on MPL.
- A spectacular success: I worked on science and operations for the Imager for Mars Pathfinder (IMP) . Check the Mars Pathfinder site at JPL for mission information and results. See the dust devil images from Sols 10 and 11.
Studies of Saturn's moon Titan.
- Mapping Titan's surface: I am on the team that used the Hubble Space Telescope (HST) to map Titan's surface in 1994. We are updating those maps with more recent images. I have also participated in the use of ground based observations to see Titan's surface.
- Titan's atmosphere: My dissertation focused on models of Titan's haze as fractal aggregate aerosols. In 1997, I used HST's STIS, NICMOS, and WFPC2 to continue studies of Titan's haze.
I participated in the Galileo Probe Net Flux Radiometer (NFR) investigation, which studied clouds and radiation on Jupiter.
