I am a laser spectroscopist who studies physical and chemical processes that are important in the upper atmospheres of Earth, Mars, and Venus. The Castle group performs laboratory measurements of key kinetic parameters that will help improve atmospheric models. Applications of our work include global climate tracking and understanding the relationships between space vehicles in low earth orbit and the upper atmosphere.
Ever wonder what ozone looks like when it’s adsorbed on silica gel at -40 oC? Purple!
