Dr. Swindle uses measurements of the noble gases in extraterrestrial materials (lunar samples and meteorites) to study the evolution of the solar system.

His research projects include using 40Ar-39Ar dating to determine the timing of impact events on the Moon and on asteroids, and studying Martian meteorites to understand the history of the Martian atmosphere and its interaction with surface materials. Past research projects have included using I-129, and its decay product Xe-129, to study the timing of the formation of the earliest solids in the solar nebula, and working on developing techniques to use instruments on spacecraft to measure ages of planetary surfaces in situ.

Jeff's research program is directed towards the development of crop production management strategies (primarily irrigated cotton and cantaloupes) that optimize the soil-plant system agronomically and economically, with full consideration of the short- and long-term impact of inputs environmentally. A study of the soil-plant relationships regarding nurtrients essential to cotton and cantaloupes is an important part of the program. Salinity and sodicity management in agricultural soils is an important part of the program. The overall goal, by interacting with other programs, is to reduce the level of inputs such as pesticides, fertilizers, and irrigation water, and maintain profitability and sustainability in both the short- and long-term agricultural production systems in the desert Southwest.

Dr. McCarthy has a passion for combining astronomical research and inquiry-based science education. He pioneered techniques for achieving high angular resolution at infrared wavelengths from both ground and space based telescopes by developing new techniques and instrumentation for interferometry, speckle imaging, active tip/tilt correction, and adaptive optics. With these tools, he initiated the direct detection of low mass companions to nearby stars, imaged the near-infrared emission from the Galactic Center source Sgr A*, examined the surface characteristics of asteroids, moons, and Kuiper Belt Objects, and recently detected atmospheric waves on Pluto. Since 1989, his Astronomy Camps have attracted teenage students, educators, schools, and general adults from around the world.
