Clouds made up of rocks and metals\, and hazes comprised of hydroc arbon soots and sulfurs block the spectral signatures of key atmospheric molecules.  This impacts their brightness when seen in reflected and emit ted light. In other words\, not only do clouds and hazes prevent us from gaining knowledge of exoplanets' atmospheric composition\, but they also strongly affect the way we interpret current and future direct imaging ob servations. Understanding exoplanet atmospheres requires that we also und erstand the behavior of these clouds and hazes. In his talk\, Dr. Gao wil l discuss current efforts in modeling clouds and hazes in exoplanet atmos pheres\, with a focus towards the application of cloud physics in determi ning possible exoplanet cloud/haze distributions. \n\n\nDr. Gao holds a P hD in Planetary Sciences from the California Institute of Technology\, wh ere he did his thesis on Clouds and Hazes in Planetary Atmospheres.  He e arned an MS in Planetary Sciences\, also from CalTech. Currently\, Peter Gao is a NASA Postdoctoral Program Fellow at the NASA Ames Research Cente r at Moffett Field\, CA. Here\, he performs research on modelling clouds and hazes on exoplanets and Brown Dwarfs\, with applications to ongoing a nd future missions and observing campaigns.
